Questions and answers

The size of the hose or fitting on each side, read as an actual end size. POWERTEC lists its 70135 as nominal 4-inch OD with an end that tapers from 3-29/32 to 3-31/32 inches, which is made to go inside 4-inch hose. More in Blast gates

Choose by the ends first; the body is a maker description. POWERTEC describes the 70135 as a cast aluminum body with a steel sliding gate. We found no source that compares metal and plastic gates in use. More in Blast gates

We found no measurement in our sources. Makers' wording such as 'designed for eliminating air leakage' is not a measured figure, so we do not repeat it as fact. More in Blast gates

A gate lets you close branches you are not using. On a collector with more than one inlet opening, Harbor Freight's 59726 manual says to cap the unused inlet with the supplied cap when only one inlet is in use. Follow your own collector's manual. More in Blast gates

One whose ends fit what they join. POWERTEC's 70135 outlet is nominal 4-inch OD, tapering from 3-29/32 to 3-31/32 inches, sized to go inside a 4-inch hose. More in Blast gates: sizes, end types, metal vs plastic

Check each maker's description. POWERTEC's 70135 outlet is a nominal 4-inch OD end sized to go inside hose, and Infinity says its 4-inch gate has tapered fittings on both sides to accept 4-inch hose. More in Blast gates: sizes, end types, metal vs plastic

No source in our register measures leakage or clogging for either, so we cannot say. Compare the ends and the features each maker states. More in Blast gates: sizes, end types, metal vs plastic

Where the gate maker says so. Infinity says hose clamps are required on its 4-inch blast gate. More in Blast gates: sizes, end types, metal vs plastic

No. Their 4 in ends are male and sized to go inside 4 in ID hose. POWERTEC lists the 70135's end as tapering from 3-29/32 to 3-31/32 inches, so a 4 in OD port needs a cuff or a short hose between them. More in 4 in blast gates with stated end sizes

One per hose end. Infinity Tools says hose clamps are required on its 4-inch gate, and the same applies to any gate with tapered hose ends. More in 4 in blast gates with stated end sizes

No. We cover manual gates only, with no switches, remotes or wiring. More in 4 in blast gates with stated end sizes

It depends on what pulls the air. Oneida says the smaller Dust Deputy is not meant for 4-inch hoses or single-stage dust collectors and points those users to its Super Dust Deputy, which it markets for 1/2 hp to 3 hp single-stage collectors. More in Cyclone separators and lids

Dustopper's FAQ attributes bucket collapse to too much airflow restriction, such as very long or small-diameter hoses. Oneida and Dustopper both advise a bucket wall of 90 mil or more. The bucket collapse guide covers both. More in Cyclone separators and lids

Not reliably. The EPA states that a cyclone's collection efficiency is directly related to the particle size distribution. Makers' separation percentages are their own claims, and we make no air-quality or health claim for any separator. More in Cyclone separators and lids

No. Dustopper says the PRO fits most standard 5-gallon buckets and advises one 90 mil thick or more. Oneida advises 90 mil or more for its Dust Deputy and says the thickness is usually marked on the bucket bottom. More in Cyclone separators and lids

The Deluxe kits do: Oneida lists a 5-gallon, 100-mil bucket for AXD000004B and AXD250004. Check the contents of the exact model you are buying. More in Cyclone separator kits: what is in the box and what is not

On the Dustopper, the top port connects to the vacuum and the front port is the pickup, per Dustopper's FAQ. Other separators differ, so read your own manual. More in Cyclone separator kits: what is in the box and what is not

A bucket and the hoses and elbows. Dustopper says its PRO separator-only version comes without elbows and hose, and its PRO kit lists no bucket. More in Cyclone separator kits: what is in the box and what is not

Not on our advice. Oneida says the Dust Deputy is designed for light debris such as wood dust, and Shop-Vac warns against vacuuming hazardous materials; follow the makers' manuals. More in Cyclone separator kits: what is in the box and what is not

Oneida says no: the smaller Dust Deputy is not meant for 4-inch hoses or single-stage collectors, and it points those users to its Super Dust Deputy, matched to the collector's intake size. More in Shop-vac cyclone or collector cyclone? Matching the separator to the machine

Oneida markets the 4/5 for 1/2 hp to 3 hp single-stage collectors, which takes in 1.5 hp. Match it to your collector's intake size as well. More in Shop-vac cyclone or collector cyclone? Matching the separator to the machine

It depends on the model. Oneida shows the original Dust Deputy with tapered 2-inch OD, 1-7/8-inch ID ports, and says the Dust Deputy 2.5 has female ports for standard 2.5-inch cuffed shop-vac hose fittings. More in Shop-vac cyclone or collector cyclone? Matching the separator to the machine

The EPA says a cyclone's collection efficiency depends on particle size, and designs that catch finer particles need a higher pressure drop. We make no health or exposure claim for any separator. More in Shop-vac cyclone or collector cyclone? Matching the separator to the machine

Oneida advises against old, damaged or thin-walled buckets and recommends a wall of 90 mil or more, usually marked on the bucket bottom. Dustopper also points to airflow restriction from very long or small-diameter hoses. More in Why a separator bucket collapses, and which buckets the makers name

Oneida recommends 90 mil or more for its Dust Deputy separators, and Dustopper advises 90 mil (0.090 inch) or thicker for its own. More in Why a separator bucket collapses, and which buckets the makers name

Dustopper says the PRO fits most standard 5-gallon buckets, not all, and gives no rim dimensions. Check the fit on your bucket. More in Why a separator bucket collapses, and which buckets the makers name

With a lid made for one. Grizzly says the Shop Fox W1049 lid fits a standard 30-gallon metal trash can, not included, but gives no rim dimensions, so check the fit yourself. More in Why a separator bucket collapses, and which buckets the makers name

No Dust Deputy kit is in our approved catalog yet. Oneida's manual lists the Dust Deputy Deluxe kit contents, including a 5-gallon 100-mil bucket, a 2-inch by 36-inch hose and two 2-inch elbows; the kits guide compares them. More in Shop-vac cyclone separators with stated ports and bucket

Dustopper's FAQ says the top port connects to the vacuum and the front port is the pickup. Other separators lay their ports out differently. More in Shop-vac cyclone separators with stated ports and bucket

These are shop-vac separators. Oneida, for example, says its smaller Dust Deputy is not meant for 4-inch hoses or single-stage collectors and points those users to its Super Dust Deputy. More in Shop-vac cyclone separators with stated ports and bucket

No plumbing standard approves it. ASTM D2729 covers sewer and drain pipe and ASTM D1785 covers Schedule 40, 80 and 120 pipe; neither addresses dust collection. If you use PVC, use adapters made for that pipe and follow your collector maker's instructions. More in Wyes, elbows and reducers

Not directly, according to Rockler, which says PVC sewer-and-drain pipe does not connect to most dust fittings without an adapter. Woodcraft's WoodRiver S&D adapter fits inside 4-inch S&D pipe and works only with left-hand threaded hose. More in Wyes, elbows and reducers

It depends on the reducer. POWERTEC says its 70136 cone reducer fits hoses only and is not meant for equipment ports, while its 70291 has a 4-inch end that friction-fits inside a 4-inch nominal OD machine port. Read where each end goes. More in Wyes, elbows and reducers

A wye joins a branch at an angle; a tee joins it square. No source we verified compares the two in use, so we do not rank them. Match whichever you choose to the standard of the run. More in Wyes, elbows and reducers

One whose maker says that end fits a port. POWERTEC says its 70291 friction-fits inside a 4-inch nominal OD machine port, while its 70136 cone reducer is for hoses only. More in 4 in to 2-1/2 in reducers: into a hose or onto a port?

Often because it was made for hoses, not ports. POWERTEC says the 70136 is not intended to fit a 2-1/2-inch OD or 4-inch OD equipment port directly. More in 4 in to 2-1/2 in reducers: into a hose or onto a port?

No. POWERTEC's 70147 has a 2.26-inch OD small end, while the 2-1/2-inch end of its 70136 is 2-15/32 inches OD. More in 4 in to 2-1/2 in reducers: into a hose or onto a port?

POWERTEC claims its 70147 increases air flow and velocity, but its page gives no data or method, so we treat it as an unverified maker claim. More in 4 in to 2-1/2 in reducers: into a hose or onto a port?

We can speak to fit only. ASTM D2729 and D1785 are plumbing standards that do not address dust collection, so neither approves it; what they do tell you is which adapter the pipe needs. More in Duct fitting standards: hose fittings, S&D PVC, Schedule 40 and metal

Not directly in most cases. Rockler says sewer-and-drain pipe does not connect directly to most dust fittings without an adapter, and it sells a separate adapter (52680) for Schedule 40. More in Duct fitting standards: hose fittings, S&D PVC, Schedule 40 and metal

They are different standards: ASTM D2729 for PVC sewer pipe and fittings, ASTM D1785 for Schedule 40, 80 and 120 pipe. Each needs its own adapter. More in Duct fitting standards: hose fittings, S&D PVC, Schedule 40 and metal

Only through an adapter made for both sides of each joint. We have no verified dimensions for snap-lock pipe, so use the metal duct maker's own transitions. More in Duct fitting standards: hose fittings, S&D PVC, Schedule 40 and metal

No. S&D is made to ASTM D2729 for sewer pipe and fittings; Schedule 40 is made to ASTM D1785. They need different adapters. More in Sewer-and-drain vs Schedule 40 PVC for dust collection

No source in our register compares them for dust use, so we compare fit only. Pick one and buy adapters made for it. More in Sewer-and-drain vs Schedule 40 PVC for dust collection

Read the standard printed along the pipe: D2729 for sewer-and-drain, D1785 for Schedule 40. If there is no print, ask the seller or pipe maker. More in Sewer-and-drain vs Schedule 40 PVC for dust collection

Yes. Rockler says S&D does not connect directly to most dust fittings without an adapter, and Woodcraft's WoodRiver S&D adapter fits inside 4-inch S&D with a 4.065-inch ID. More in Sewer-and-drain vs Schedule 40 PVC for dust collection

One part for each joint: a collector-inlet connection, main line, wyes, elbows, a gate on each branch, a drop or hose to each tool, reducers where ports are smaller, and clamps on hose joints. Buy them all to one fitting standard. More in A small-shop duct run: the parts list, one standard at a time

It keeps adapters to a minimum. Rockler says sewer-and-drain pipe does not connect directly to most dust fittings without an adapter, so every change of standard adds a transition. More in A small-shop duct run: the parts list, one standard at a time

On each branch or drop, between the main run and the tool hose, so you can close the branches you are not using. Check each gate's ends: Infinity says its 4-inch gate needs hose clamps. More in A small-shop duct run: the parts list, one standard at a time

OSHA's 1997 bulletin cites an older NFPA 664 requirement that collectors be outside buildings, with exceptions, for workplaces. It is not current home code; follow your collector maker and current NFPA guidance. More in A small-shop duct run: the parts list, one standard at a time

Not the 70136, which POWERTEC says fits hoses only. POWERTEC's 70291, which is not in our catalog, has a 4-inch end that tapers from 3.51 to 3.73 inches and friction-fits inside a 4-inch nominal OD machine port. More in Reducers and adapters with both ends dimensioned

No. They are hose fittings. Pipe needs an adapter made for its standard, such as Rockler's Schedule 40 to 4-inch fitting adapter or Woodcraft's WoodRiver S&D adapter. More in Reducers and adapters with both ends dimensioned

Because they are made to go inside 4 in hose. The label is the family; POWERTEC's 70136 4-inch end is 3-61/64 inches OD. More in Reducers and adapters with both ends dimensioned

No. ASTM D2729 is the specification for PVC sewer pipe and fittings, and ASTM D1785 covers PVC pipe in Schedule 40, 80 and 120. Both are plumbing standards; neither addresses dust collection. More in Duct fitting standard finder

Read the print on the pipe: it names the standard, such as ASTM D2729 for sewer and drain or ASTM D1785 for Schedule 40. Our sources give no reliable visual rule, so trust the marking. More in Duct fitting standard finder

No source we verified states that value for the standard. Several standards here have thin published data, and we leave those fields blank rather than guess. More in Duct fitting standard finder

The one that fits its inlet, which you read from the maker. Grizzly lists the G8027 as a 1 HP collector with a 4-inch intake, and its data sheet says no inlet adapter is included. Check your own model in the inlet finder. More in Dust-collector hose

We have no measured answer for home shops, and we publish no airflow figures. Follow your collector maker's inlet and instructions; the hose length and diameter guide covers what the evidence does and does not show. More in Dust-collector hose

A fitting on the collector's inlet that splits one opening into two. Grizzly's parts list for the Shop Fox W1685 shows a 6-inch to two 4-inch inlet Y for version V2.12.01 and an earlier 5 x 4 x 4 inlet for V1, so check your machine's version. More in Dust-collector hose

No hose does that on its own, and we make no such claim. Makers use antistatic, dissipative and conductive for different properties; read them as maker claims, and see what OSHA and NFPA say. More in Dust-collector hose

They are different maker claims. Masterduct calls its SL-F-EC hose electrically conductive with a stated surface resistance of 10^4 ohm or less, while it says antistatic properties are standard on all its PUR hoses. More in Anti-static, dissipative and conductive hose: reading the claims

No source in our register measures that. Shop-Vac says static shocks come from static buildup and are common at low humidity, and Festool says antistatic performance needs a complete antistatic system. More in Anti-static, dissipative and conductive hose: reading the claims

We give no grounding instructions. OSHA recommends that workplaces ground equipment prone to static, and Cen-Tec says the vac tank needs to be grounded for its anti-static route to work; follow your makers' manuals. More in Anti-static, dissipative and conductive hose: reading the claims

Not by that fact alone. A wire helix holds the hose's shape; whether it is meant to be connected is the hose maker's statement to make. More in Anti-static, dissipative and conductive hose: reading the claims

Start with your collector's manual for the inlet size, then pick a hose whose inside diameter goes over the fittings you use. Infinity, for example, says its 4-inch gate's tapered ends accept 4-inch hose with clamps. More in Choosing 4 in dust-collector hose

A hose whose wire winds counterclockwise when you look at an open end, the identification Lee Valley gives. Left-hand bridge clamps and some threaded adapters fit only that hand. More in Choosing 4 in dust-collector hose

Only through an adapter made for that pipe standard. Woodcraft's WoodRiver S&D adapter, for example, fits inside 4-inch S&D pipe and works only with left-hand threaded hose. More in Choosing 4 in dust-collector hose

The maximum vacuum a hose is rated to hold and the tightest curve its maker allows. McMaster-Carr lists both for each duct hose; check whether your listing states them. More in Choosing 4 in dust-collector hose

Read your own unit's manual or data sheet. Grizzly lists a 4-inch main inlet for the G8027 and Harbor Freight a 4-inch inlet for the 59726, but those are nominal sizes for those models only. More in Dust-collector inlet sizes: 4 in inlets, inlet Ys and caps

It splits one collector inlet into two or more openings. Whether yours has one, and its sizes, depends on the model and version: Grizzly's W1685 parts list shows a 6 x 4 x 4 Y for V2.12.01 and a 5 x 4 x 4 part for V1. More in Dust-collector inlet sizes: 4 in inlets, inlet Ys and caps

Follow your manual. Harbor Freight's 59726 manual says to cap the unused inlet with the supplied inlet cap when only one inlet is in use. More in Dust-collector inlet sizes: 4 in inlets, inlet Ys and caps

Only where the maker's own inlet part is 6 inches, as on the W1685 V2.12.01 inlet Y in Grizzly's parts list. Check your machine's version first. More in Dust-collector inlet sizes: 4 in inlets, inlet Ys and caps

We could not confirm it from a verified source, so we publish no figure. Read JET's manual and parts list for your unit. More in Dust-collector inlet sizes: 4 in inlets, inlet Ys and caps

Hose choice can matter. Woodgears reports that hose choice affected airflow much more on the tested dust collectors than on the tested shop vac; it is one experimenter's equipment, so we give no figures. More in Dust hose length and diameter: what the evidence shows

Woodgears included 2.5-inch collector hose in its experiment and found hose choice mattered more on the collectors than on the shop vac. Follow your collector maker's manual for the hose it names. More in Dust hose length and diameter: what the evidence shows

Dustopper's FAQ attributes bucket collapse to too much airflow restriction, such as very long or small-diameter hoses. Use the bucket the separator maker names, and ask the maker before changing anything. More in Dust hose length and diameter: what the evidence shows

No source in our register sets a limit. Follow the collector maker's manual. More in Dust hose length and diameter: what the evidence shows

Lee Valley says you can identify a left-hand spiral when the wire spirals counterclockwise at an open end. Its left-hand bridge clamps fit only such hoses. More in 4 in dust-collector hoses with stated ends and wall

If your collector maker lists a 4 in inlet, start there. Grizzly's G8027 data sheet and Harbor Freight's 59726 manual both list a 4-inch inlet; check your own model and version in the inlet finder. More in 4 in dust-collector hoses with stated ends and wall

No maker page we verified documents a 5 or 6 in hose product, so none is listed. Our 5 and 6 in data covers collector inlets and separator ports only. More in 4 in dust-collector hoses with stated ends and wall

No. They are reference machines that hoses and fittings attach to. We list what their makers state about the inlet so you can match parts, and we never recommend a vacuum, extractor or collector. More in Vacuum and collector inlet finder

Read the version code on your machine and compare it with Grizzly's parts list, which shows a 6 x 4 x 4 inlet Y for V2.12.01 and an earlier 5 x 4 x 4 inlet for V1. Grizzly explains that a code such as V2.01.17 means version 2, first used in January 2017. More in Vacuum and collector inlet finder

Read the inlet from the maker's manual or data sheet for your model and version, then measure the inlet's inside and outside diameter, as Rockler advises for every port. More in Vacuum and collector inlet finder

One whose stated range covers the hose's outside diameter with the fitting inside it. A 4 in hose is sold by its inside diameter, so measure the outside once it is on the fitting, as Rockler advises measuring both diameters. More in Hose cuffs, clamps and couplers

Match the hose. Lee Valley says its left-hand bridge clamps fit only hoses with a left-hand spiral, which you can spot when the wire spirals counterclockwise at an open end, and it sells right-hand clamps separately. More in Hose cuffs, clamps and couplers

With a coupler made for both hose ends. Shop-Vac's 170400 coupling is a polypropylene part that joins two 2-1/2-inch wet/dry vacuum hoses, and the adapter that comes with Shop-Vac's 5430133 hose can join two hoses too. More in Hose cuffs, clamps and couplers

Do not assume so. Cen-Tec says its 34982 cuff threads onto 1.25-inch crush-proof hose, and its page does not say the thread is NPT. A hose cuff's thread is made for the hose it names. More in Hose cuffs, clamps and couplers

One whose range covers the hose's outside diameter where it sits over the fitting, which is larger than the 4-inch label. Measure it on the installed joint. More in Dust hose clamps: sizing by outside diameter and spiral direction

A band clamp with a raised bridge that steps over the hose's wire. Lee Valley says its left-hand bridge clamps fit only left-hand spiral hose and need at least 1/2 inch between coils. More in Dust hose clamps: sizing by outside diameter and spiral direction

Look into an open end and follow the wire. Lee Valley says a left-hand spiral is one where the wire spirals counterclockwise at an open end. More in Dust hose clamps: sizing by outside diameter and spiral direction

Use one where the part maker says so. Infinity says hose clamps are required on its 4-inch blast gate, and each of its MagSnap ports includes one. More in Dust hose clamps: sizing by outside diameter and spiral direction

With a coupler made for their size. Shop-Vac's item 170400 joins two 2-1/2-inch wet/dry vac hoses, and the adapter supplied with its 5430133 hose can join two hoses. More in Hose cuffs and couplers: threads, slip ends and hose-to-hose joints

Yes, if the cuff's maker says it fits that hose's size and type. Cen-Tec's 42324, for example, threads onto 1.25-inch spiral hose. More in Hose cuffs and couplers: threads, slip ends and hose-to-hose joints

Do not assume so. Cen-Tec's 34982 cuff threads onto 1.25-inch crush-proof hose, and its page does not say the thread is NPT. More in Hose cuffs and couplers: threads, slip ends and hose-to-hose joints

Your hose may be blow-molded. Cen-Tec says its threaded hose fittings fit 1-1/4-inch threaded crushproof hose and are not compatible with most blow-molded hoses supplied with shop vacuums. More in Hose cuffs and couplers: threads, slip ends and hose-to-hose joints

No. Lee Valley says its left-hand bridge clamps fit only hoses with a left-hand spiral, and it sells right-hand clamps separately. More in Hose clamps and couplers matched to hose OD

No source we verified compares them. Shop-Vac's 170400 is a rigid polypropylene coupling for two 2-1/2-inch wet/dry vacuum hoses; Rockler's union is rubber with clamps. Choose by the ends you have to join. More in Hose clamps and couplers matched to hose OD

Infinity Tools includes a hose clamp with each MagSnap port, so the hose is still clamped onto the port. More in Hose clamps and couplers matched to hose OD

Both. Rockler advises measuring the inside and outside diameter of each tool port and hose connector, because the port's outside diameter has to match the hose's inside diameter. The measuring guide shows how. More in Measuring and buying

Find the maker's own page for the part and compare. A listing that gives each end's size and matches the maker's page is a good sign; one that says only "universal" or "fits all" with no diameters is a reason to stop. More in Measuring and buying

The seller. Amazon's return policy says items shipped by third-party sellers go back to the seller, who must offer a US return address, a prepaid label or a returnless refund. Most items can be returned within 30 days of delivery, with exceptions. More in Measuring and buying

Check; we never assume it. Read 'Ships from' and 'Sold by' on the order page. A third-party review that mentions a brand's Amazon store is not proof that a seller is the brand. More in Measuring and buying

Not necessarily, so check. Read 'Ships from' and 'Sold by' on the order page. A listing that shows Amazon as the shipper does not tell you who sells it, and a third-party review that mentions a brand's Amazon store is not proof either. More in Buying dust-collection fittings online: a checklist before you order

Usually, on the seller's terms. Amazon says most items can be returned within 30 days of delivery, with exceptions, and third-party items go back to the seller, who must offer a US return address, a prepaid label or a returnless refund. Read the order page before you buy. More in Buying dust-collection fittings online: a checklist before you order

Only for some items. AliExpress's Free Returns terms apply only to products with the Free Returns icon from sellers in the program, and the current terms say the return period is what the order page shows. More in Buying dust-collection fittings online: a checklist before you order

Search cpsc.gov/Recalls, as the CPSC tells online buyers to do. The CPSC says selling a recalled product is illegal. Finding no recall is not proof that a part fits or is safe. More in Buying dust-collection fittings online: a checklist before you order

Both. Rockler advises measuring the inside and outside diameter of each port and hose connector, because the port's outside diameter has to match the hose's inside diameter. More in How to measure a dust port: inside or outside diameter

A caliper is easiest: close the outside jaws across the widest point for the outside diameter and open the inside jaws for the inside diameter. A ruler laid across the center of the opening works if you read it carefully at the widest point. More in How to measure a dust port: inside or outside diameter

Record both the smallest and the largest diameter. Makers publish tapered ends as a range, for example POWERTEC lists the 4-inch end of its 70291 as tapering from 3.51 to 3.73 inches. More in How to measure a dust port: inside or outside diameter

Not quite. One inch is exactly 25.4 mm, so 35 mm is about 1.378 inches and 1-3/8 inches is about 34.9 mm. That arithmetic does not make a metric part and an inch part interchangeable. More in How to measure a dust port: inside or outside diameter

Measure the port yourself and ask the maker. Makita's SP6000J page, for example, describes the same port as 1-7/16 inch in one bullet and as a 1-1/2 inch OD port in another. More in How to measure a dust port: inside or outside diameter

Not necessarily. The label names a family. POWERTEC's 70136, for example, lists its "2-1/2-inch" end at 2-15/32 in OD and 2-9/32 in ID, and neither figure is 2.5 in. More in Nominal vs actual dust hose sizes: why "2-1/2 in" does not mean 2.5 in

The "4-inch" on each part can describe a different surface. POWERTEC's 70147 has a 3.965 in OD on its 4-inch end, while its 70291 tapers from 3.51 to 3.73 in to fit inside a 4-inch nominal OD port. Compare the two surfaces that actually meet. More in Nominal vs actual dust hose sizes: why "2-1/2 in" does not mean 2.5 in

It is the size family the part belongs to, not a measured diameter. It may refer to a hose bore, a cuff's outside diameter or a port, depending on the maker. More in Nominal vs actual dust hose sizes: why "2-1/2 in" does not mean 2.5 in

No. They are different labels, and some parts are sold to bridge them. Even makers can blur them: DEWALT Canada's DWV9190 page gives the same part as 2-1/2 in and as 57.2 mm, which is 2-1/4 in. More in Nominal vs actual dust hose sizes: why "2-1/2 in" does not mean 2.5 in

OSHA lists wood among materials that can form combustible dust, and says finely divided combustible dust suspended in air at the right concentration can become explosible under certain conditions. That is a general statement, not a verdict on any home shop. More in Wood dust, fire and static: what OSHA and NFPA say, and what we do not cover

We do not say so, and we give no grounding instructions. OSHA's woodworking guidance lists static discharges among ignition sources and recommends that workplaces ground equipment prone to static. Follow your collector or vacuum maker's manual. More in Wood dust, fire and static: what OSHA and NFPA say, and what we do not cover

Follow your vacuum maker's manual; we give no advice on hazardous or very fine materials. Shop-Vac warns not to vacuum toxic, carcinogenic, combustible or other hazardous materials such as asbestos, arsenic, lead or pesticides with its vacuums. More in Wood dust, fire and static: what OSHA and NFPA say, and what we do not cover

OSHA's 1997 bulletin cited an older NFPA 664 rule that collectors be outside buildings, with limited exceptions. That is a historical, workplace citation, not current home code. Follow the maker's installation instructions, as the bulletin itself stresses. More in Wood dust, fire and static: what OSHA and NFPA say, and what we do not cover

Neither maker says so. Cen-Tec documents its Quick Click parts and Rockler documents its Click-Connect parts, each as its own system, so buy the hose end and the tool adapters from one system. More in Quick-connect systems

At least two halves per joint. Magport says its 4-inch magnetic coupling is sold individually but needs more than one unit to operate, and Infinity sells MagSnap as a magnet version for the collector side and a ring version for the tool side. More in Quick-connect systems

Usually not. Cen-Tec says its 41125 and 40751 threaded fittings fit 1-1/4-inch threaded crushproof hose and are not compatible with most blow-molded hoses supplied with shop vacuums. More in Quick-connect systems

We found no published figure. Infinity Tools lists MagSnap materials (ABS, rare-earth magnets, metal rings) and includes a hose clamp with each port, but publishes no holding-force or leakage numbers. More in Quick-connect systems

No source in our register says they interconnect. Buy the hose fitting and the tool-end parts from the same system. More in Cen-Tec Quick Click vs Rockler Click-Connect: parts, sizes and hose fit

Cen-Tec says its threaded fittings are not compatible with most blow-molded hoses supplied with shop vacuums. Rockler says the hose needs its #68066 Click-Connect adapter to click into a FlexiPort. The simplest route with either is a kit that includes its own hose. More in Cen-Tec Quick Click vs Rockler Click-Connect: parts, sizes and hose fit

Neither maker's page in our register gives an airflow figure, and we do not test products, so we can't say. Choose by port fit and hose. More in Cen-Tec Quick Click vs Rockler Click-Connect: parts, sizes and hose fit

Cen-Tec describes the 95567 hose as static dissipative, and sells a 40751 fitting it calls antistatic. Those are Cen-Tec's words; we make no fire or shock safety claim from them. More in Cen-Tec Quick Click vs Rockler Click-Connect: parts, sizes and hose fit

DEWALT names the DWV9000 for connecting sanders such as the DWE6423 and DCW210B to vacuums other than its DWV010 and DWV012, when those vacuums have 1-1/4-inch hoses. More in DEWALT AirLock and the DWV9000: what each adapter joins

DEWALT names it for 1-1/4-inch hoses. For a 2-1/2-inch hose OD similar to RIDGID or Shop-Vac, DEWALT Canada names the DWV9190 large hose adapter, used with the DWV9000. More in DEWALT AirLock and the DWV9000: what each adapter joins

DEWALT lists a 36 mm AirLock adapter (DWV9036) and a 36 mm anti-static hose (DWV9336). That makes 36 mm one AirLock size DEWALT sells, not a general metric standard. More in DEWALT AirLock and the DWV9000: what each adapter joins

No. DEWALT says the DWE6423 and DCW210B ports fit its DWV010 and DWV012 directly, and names the DWV9000 for other vacuums with 1-1/4-inch hoses. More in DEWALT AirLock and the DWV9000: what each adapter joins

No maker in our sources says its halves mate with another brand's. Woodcraft lists MagFitt's coupling as working with MagFitt's own connectors and says nothing about Magport, so buy both halves in one system. More in Magnetic dust fittings: Magport, MagFitt and MagSnap

At least two. Magport says its 4-inch coupling is sold individually but needs more than one unit to operate. More in Magnetic dust fittings: Magport, MagFitt and MagSnap

It depends on the system. Infinity's MagSnap puts the magnet version on the collector side and the ring version on the tool side; Woodcraft says MagFitt's machine coupling has a steel ring and mates with MagFitt's hose connector. More in Magnetic dust fittings: Magport, MagFitt and MagSnap

No maker or independent figure in our sources says. Infinity publishes no holding-force or leakage figures for MagSnap, and the other pages give none either. More in Magnetic dust fittings: Magport, MagFitt and MagSnap

The one whose maker lists your tools and your hose. No source in our register ranks these systems by measured performance, so pick by fit and by how many adapters you need. More in Quick-connect dust hose systems: Cen-Tec, Rockler and DEWALT AirLock

No source in our register says Cen-Tec Quick Click and Rockler Click-Connect parts interconnect. Treat each as a closed system and buy the hose fitting and tool adapters from the same maker. More in Quick-connect dust hose systems: Cen-Tec, Rockler and DEWALT AirLock

Probably not. Cen-Tec says its 41125 and 40751 threaded fittings fit 1-1/4-inch threaded crushproof hose and are not compatible with most blow-molded hoses supplied with shop vacuums. More in Quick-connect dust hose systems: Cen-Tec, Rockler and DEWALT AirLock

One tool-end adapter per tool in that system. Cen-Tec sells TPE tool adapters in 0.75, 1, 1.25 and 1.5-inch labels, and Rockler sells Click-Connect FlexiPorts that need its 68066 hose adapter on the hose. More in Quick-connect dust hose systems: Cen-Tec, Rockler and DEWALT AirLock

Neither maker documents it. Rockler says FlexiPorts need its Click-Connect hose adapter to click into place, and Cen-Tec documents its own fittings and adapters, so keep each system's halves together. More in Quick-connect hose kits: what each kit includes

Not on this shortlist. Magnetic systems are sold in 4 in: Infinity Tools sells MagSnap ports in 4-inch and 2-1/2-inch sizes, with a magnet half for the collector side and a ring half for the tool side. More in Quick-connect hose kits: what each kit includes

Usually not. Cen-Tec says its 41125 and 40751 fittings fit 1-1/4-inch threaded crushproof hose and are not compatible with most blow-molded hoses supplied with shop vacuums. More in Quick-connect hose kits: what each kit includes

Read the size on the vacuum maker's page or manual for your model, then measure the tank inlet. Most shop-vac hoses are sold as 1-1/4, 1-7/8 or 2-1/2 in, but the label is a family name; the hose size finder shows what each label measures. More in Shop-vacuum hoses

RIDGID says its LA2522 hose fits all RIDGID 2-1/2-inch inlet configurations and makes no claim about other brands' tanks. CRAFTSMAN says its CMXZVBE38759 kit fits CRAFTSMAN and most wet/dry vacs using a 2-1/2-inch hose. Buy the hose whose maker names your tank, or check the lock style first. More in Shop-vacuum hoses

It is the stretched length. RIDGID describes its LA2522 as a hose that extends up to 20 feet, so its relaxed length is shorter. Compare stretched length with stretched length across listings. More in Shop-vacuum hoses

Only if you can fit a new end that matches the hose type. Cen-Tec says its threaded cuffs fit 1-1/4-inch threaded crushproof hose and are not compatible with most blow-molded hoses supplied with shop vacuums, so a cut blow-molded hose may have no cuff that fits. See hose cuffs and couplers. More in Shop-vacuum hoses

Use a tank-end cuff whose outside diameter matches your vac's inlet and whose other end matches your hose. Cen-Tec's 42324, for example, threads onto 1.25-inch spiral hose and ends in a 2.25-inch OD press fit. More in Connecting a 1-1/4 in hose to a bigger shop-vac inlet

Probably not. Cen-Tec says its 41125 and 40751 threaded fittings fit 1-1/4-inch threaded crushproof hose and are not compatible with most blow-molded hoses supplied with shop vacuums. More in Connecting a 1-1/4 in hose to a bigger shop-vac inlet

Cen-Tec lists a 2.5-inch ID tank opening for its 62909 adapter made for Milwaukee FUEL wet-dry vacuums. It names no specific Milwaukee models, so confirm yours. More in Connecting a 1-1/4 in hose to a bigger shop-vac inlet

No source in our register measures that, so we keep this page to fit. Many owners keep their vac's larger stock hose for floors and use a small hose on tool ports. More in Connecting a 1-1/4 in hose to a bigger shop-vac inlet

RIDGID says its LA2522 fits every RIDGID 2-1/2-inch inlet configuration and makes no claim about other brands. CRAFTSMAN says its CMXZVBE38759 fits CRAFTSMAN and most wet/dry vacs using a 2-1/2-inch hose. More in Replacement shop-vac hoses: RIDGID, CRAFTSMAN and Shop-Vac by part number

No. RIDGID's "extends up to 20 feet" for the LA2522 describes the stretched length. A stretch hose pulls back toward its relaxed length, so plan your reach shorter than the maximum. More in Replacement shop-vac hoses: RIDGID, CRAFTSMAN and Shop-Vac by part number

Only if your vac's inlet is a locking type. RIDGID and CRAFTSMAN kits include locking adapters, and RIDGID's also includes a friction-fit adapter; check which adapters each kit supplies against your tank. More in Replacement shop-vac hoses: RIDGID, CRAFTSMAN and Shop-Vac by part number

Use a coupler. Shop-Vac's 170400 is a polypropylene coupling that joins two 2-1/2-inch wet/dry vacuum hoses, and the adapter supplied with its 5430133 hose can join two hoses too. More in Replacement shop-vac hoses: RIDGID, CRAFTSMAN and Shop-Vac by part number

Check the vac's manual or the maker's replacement-hose page for your model; the common families are 1-1/4, 1-7/8 and 2-1/2 in. If you have no paperwork, measure the hose end and the tank inlet, inside and outside. More in Shop-vac hose sizes: 1-1/4 vs 1-7/8 vs 2-1/2 in

Only with a tank-end cuff or adapter made for your inlet. Cen-Tec, for example, sells a 42324 cuff that threads onto 1.25-inch spiral hose and ends in a 2.25-inch OD press fit for the tank. More in Shop-vac hose sizes: 1-1/4 vs 1-7/8 vs 2-1/2 in

No. 1-7/8 in is its own hose family. Shop-Vac sells 1-7/8-inch hoses for vacs with a 1-7/8-inch inlet and supplies an adapter with its 5430133 hose that converts the end to 2-1/2 in. More in Shop-vac hose sizes: 1-1/4 vs 1-7/8 vs 2-1/2 in

Whatever the sander maker's own route names. DEWALT and Bosch both name adapters for 1-1/4-inch hoses; see the sander guide for each route. More in Shop-vac hose sizes: 1-1/4 vs 1-7/8 vs 2-1/2 in

Only approved catalog products appear in picks. RIDGID and Shop-Vac publish their own hose details, which the replacement hose guide covers. More in Shop-vac hoses whose maker states the size, length and ends

CRAFTSMAN says it fits CRAFTSMAN and most wet/dry vacs using a 2-1/2-inch hose; it does not list RIDGID models. RIDGID says its own LA2522 fits all RIDGID 2-1/2-inch inlet configurations. More in Shop-vac hoses whose maker states the size, length and ends

Check the listing. For its LA2522, RIDGID says the hose extends up to 20 feet, which describes the stretched length. Compare stretched lengths with stretched lengths. More in Shop-vac hoses whose maker states the size, length and ends

Not necessarily. The label is a family name. POWERTEC's 2-1/2-inch reducer end, for example, measures 2-15/32 inches OD and 2-9/32 inches ID, so check what each part's maker states. More in Dust hose size finder

NIST states that the inch is exactly 25.4 mm, so divide millimeters by 25.4. A converted figure is still only a guide; match the end your hose and port actually have. More in Dust hose size finder

No source we verified states that value for the size family. We leave it blank rather than fill it from seller listings. More in Dust hose size finder

Look up the tool on its maker's page first, then measure. Rockler advises measuring both the inside and outside diameter of each port and hose connector, because the port's outside diameter has to match the hose's inside diameter. The dust port finder lists what makers state for six tools. More in Tool-port adapters

No. A step or flexible adapter fits the range its maker states, and only that. Rockler lists its FlexiPort 64358 as a 3/4-inch ID by 1-1/4-inch OD rubber end with no stretch range, and Cen-Tec's adjustable 41851 has a stated range of 0.5 to 2.63 inches, which is a claim, not proof for every port. More in Tool-port adapters

No, but the maker's route is the one it documents. DEWALT says the DWE6423 port fits its DWV010 and DWV012 extractors directly and names the DWV9000 connector for other vacuums with 1-1/4-inch hoses. Bosch names its VAC002 or VAC024 adapters for 1-1/4- or 1-1/2-inch hose on the ROS20VSC. More in Tool-port adapters

Not exactly. NIST defines the inch as exactly 25.4 mm, so 35 mm is about 1.38 in, but a metric label is still a family name. Match the end your hose actually has, as the metric hose guide explains. More in Tool-port adapters

Pick the part whose page names your hose diameter. Festool lists the 577162 sleeve for D 27 and D 27/32 suction hoses and tools with D 27 and D 36 flanges. More in Festool hose sleeves and connectors: D 27, D 36 and the CT inlet

Festool USA lists the 452892 rotating connector for the CT 22 and CT 33 extractor inlets only. It names no other CT models, so we don't extend it. More in Festool hose sleeves and connectors: D 27, D 36 and the CT inlet

Festool's wording covers Festool D 27 and D 36 flanges only. No source in our register says it fits another brand's 27 mm port. More in Festool hose sleeves and connectors: D 27, D 36 and the CT inlet

Festool says antistatic performance requires a complete antistatic system of extractor, hoses, sleeves and couplings. A hose by itself is one part of that system. More in Festool hose sleeves and connectors: D 27, D 36 and the CT inlet

A male end slides inside another part; its outside diameter is the mating surface. A female end slides over another part; its inside diameter is the mating surface. More in Male, female and tapered dust fittings: which end goes inside

Usually because both ends are male, or both are female. Two male ends need a coupler over them, and two female ends need a spigot or coupler inside them. If the genders are right, compare the outside diameter of the male end with the inside diameter of the female end. More in Male, female and tapered dust fittings: which end goes inside

Only if its maker says so. POWERTEC says its 70136 cone reducer fits hoses only and is not meant to fit a machine port directly, while its 70291 friction-fits inside a 4-inch nominal OD port. More in Male, female and tapered dust fittings: which end goes inside

A coupler. For 2-1/2-inch shop-vac hoses, Shop-Vac sells the 170400, a polypropylene coupling that joins two 2-1/2-inch wet/dry vacuum hoses. More in Male, female and tapered dust fittings: which end goes inside

Close on paper, not the same part. One inch is exactly 25.4 mm, so 35 mm is about 1.378 in and 1-3/8 in is 1.375 in. The arithmetic says nothing about whether the two hoses' ends fit the same port. More in 27, 32, 35 and 36 mm vacuum hoses: metric sizes are not one standard

No source in our register says so. Festool lists its sleeves for Festool D 27 and D 36 flanges, and Bosch lists its own hoses for its tools; neither names the other brand. More in 27, 32, 35 and 36 mm vacuum hoses: metric sizes are not one standard

They belong to different makers' systems. Bosch sells a 35 mm VAC005 hose with a 2-1/4-inch friction-fit vacuum end, while DEWALT sells a 36 mm AirLock adapter and a 36 mm anti-static hose. Match by each maker's list. More in 27, 32, 35 and 36 mm vacuum hoses: metric sizes are not one standard

It is Festool's label for a hose size it lists alongside D 27, for example on its 577162 sleeve "for suction hose D 27 and D 27/32". Keep to Festool's own part pages when matching one. More in 27, 32, 35 and 36 mm vacuum hoses: metric sizes are not one standard

For the routers and fixed bases Bosch lists, use the RA1172AT kit: it includes two hoods and a VAC002 adapter. Bosch names VAC002 or VAC024 for 1-1/4 and 1-1/2-inch hoses and VAC020 for 2-1/2-inch hoses. More in Router dust hoods: Bosch RA1172AT and hose adapters

Bosch lists it for the 1617, 1617EVS, 1618 and 1618EVS routers and the RA1161, RA1162, RA1164 and RA1165 fixed bases. No plunge base is on that list. More in Router dust hoods: Bosch RA1172AT and hose adapters

Bosch names the VAC020 for 2-1/2-inch hoses on the RA1172AT page. More in Router dust hoods: Bosch RA1172AT and hose adapters

Bosch doesn't state the hood's port diameter on the RA1172AT page. Measure it, or use one of the adapters Bosch names. More in Router dust hoods: Bosch RA1172AT and hose adapters

DEWALT names the DWV9000 for connecting the DWE6423 and DCW210B to other vacuums with 1-1/4-inch hoses. It does not say every other brand's cuff fits, and a 2-1/2-inch floor hose is a different size. More in Sander dust port to shop-vac hose: maker routes for DEWALT and Bosch

Yes. Bosch lists a VAC002 vacuum hose adapter in the box and names VAC002 or VAC024 for 1-1/4- or 1-1/2-inch vacuum hose. More in Sander dust port to shop-vac hose: maker routes for DEWALT and Bosch

Maybe. Makers state size ranges, such as Cen-Tec's 41851 at 0.5 to 2.63 inches, but a stated range is not proof for every port. Measure your port and compare it with the adapter maker's figures first. More in Sander dust port to shop-vac hose: maker routes for DEWALT and Bosch

No. DEWALT says the DWE6423 and DCW210B ports fit its DWV010 and DWV012 extractors directly, and names the DWV9000 for other vacuums with 1-1/4-inch hoses. More in Sander dust port to shop-vac hose: maker routes for DEWALT and Bosch

Makita's SP6000J and XPS01PTJ pages describe a large 1-7/16-inch rear dust port. The SP6000J page also calls it a 1-1/2-inch OD port in another bullet, so treat the size as unresolved and measure yours. More in Track-saw dust ports: Makita and Festool connections

Makita does not say on the XPS01PTJ page. On the SP6000J page, one bullet says 1-7/16 inch and another says 1-1/2 inch OD, which do not agree. More in Track-saw dust ports: Makita and Festool connections

No. Makita lists 194579-2 as a guide rail adapter for routers. It appears among the SP6000J's related accessories but is not a dust hose part. More in Track-saw dust ports: Makita and Festool connections

No source in our register says so for any track saw. Measure the port's inside and outside diameter, then look for an adapter whose maker states sizes that match. More in Track-saw dust ports: Makita and Festool connections

Shop-Vac describes its 3-piece adaptor kit (8019848) as polypropylene adapters for friction-connect or lock-on hoses, but names no pieces and gives no dimensions, so it fails our both-ends rule. More in Tool-port adapters with each end's diameter stated

Only within its maker's stated size. Rockler's FlexiPort 64358, for example, is listed as 3/4-inch ID by 1-1/4-inch OD with no stretch range. Measure your port's inside and outside diameter first. More in Tool-port adapters with each end's diameter stated

Bosch does not say so. Bosch names it for its own tools; DEWALT names its DWV9000 connector for its sanders on other vacuums with 1-1/4-inch hoses. More in Tool-port adapters with each end's diameter stated

Look the tool up on its maker's page for a named adapter, then measure the port's inside and outside diameter, as Rockler advises. The measuring guide shows how. More in Dust port finder by tool model

Makita's own page gives two: a 1-7/16-inch rear dust port in one place and a 1-1/2-inch OD port in another. We show both as Makita's labels and treat the real size as unresolved. More in Dust port finder by tool model

No source we verified states that value. It does not mean the value is wrong or missing from the tool, only that we could not confirm it from the maker or another named source. More in Dust port finder by tool model

Not confirmed. DEWALT names the DWV9000 for other vacuum systems with 1-1/4 in hoses but lists no other brand's hose cuff. Check your hose end first; how to measure a dust port shows what to measure. More in DEWALT DWE6423 random orbit sander

DEWALT does not state it on the product page or the support answer we read, so it is listed here as not confirmed. DEWALT gives a connection route instead of a size. More in DEWALT DWE6423 random orbit sander
