Short answer
Buy collector hose to fit your collector's inlet as its maker states it for your machine's version, usually 4 in on small single-stage collectors. Then match the hose's inside diameter to the fittings it slides over, note its spiral hand for clamps, and read wall and anti-static wording as maker claims rather than guarantees.

What this topic covers
A dust collector hose runs from the collector's inlet to a machine port, a gate or a duct. Most fittings in this size are male: they slide inside the hose and a clamp holds them. So the hose's inside diameter is the number that has to match, and the hose's wire helix decides which clamps and threaded parts fit.
The decisions, in order
1. Your collector's inlet and version. Grizzly lists the G8027 as a 1 HP collector with a 4-inch intake.[1] Its data sheet lists a 4-inch main inlet, says no inlet adapter is included, and says its information is accurate as of October 12, 2026 and may not describe machines bought earlier.[2] Harbor Freight's manual for the Central Machinery 59726 lists a 4-inch inlet.[3] The Shop Fox W1685 depends on its version: Grizzly's parts list shows a 6-inch to two 4-inch inlet Y marked V2.12.01 and an earlier 5 x 4 x 4 inlet marked V1.[4] Grizzly explains that a code such as V2.01.17 means version 2, first used in January 2017.[5] Find your model in the vacuum and collector inlet finder.
2. Hose ID against fitting OD. A nominal 4 in label on a hose and on a fitting does not prove they mate. Infinity Tools says its 4-inch blast gate has tapered fittings on both sides to accept 4-inch hose, and that hose clamps are required.[6] Magport describes its 4-inch magnetic coupling collar as a 4-inch outer diameter that fits 4-inch flex hose.[7] Both describe a male part inside the hose.
3. Spiral hand. Lee Valley says its left-hand bridge clamps fit only hoses with a left-hand spiral, which you can identify when the wire spirals counterclockwise at an open end.[8] Check the hand before you buy bridge clamps or threaded fittings.
4. Published vacuum rating and bend radius. Industrial catalogs publish these per hose. McMaster-Carr's duct hose tables list a maximum vacuum rating and bend radius for each product.[9] Many hobby listings give neither. A hose without them is not worse, only less documented.
5. Anti-static claims are claims. Masterduct describes its Master-PUR SL-F-EC as electrically conductive polyurethane with a stated surface resistance of 10^4 ohm or less.[10] That is a different property from anti-static. No hose makes a collector safe by itself; the anti-static vs conductive guide explains the words.
Length and diameter
Woodgears' one-person experiment measured inlet airflow with an anemometer over a hole in a cardboard box, testing a shop vac, a 1 hp collector and a homemade collector with several hoses.[11] It reports that hose choice affected airflow much more on the tested collectors than on the tested shop vac.[11] That is one setup's direction, not a sizing rule, and we publish no airflow numbers. See hose length and diameter: what the evidence shows.
5 and 6 in hose
Our sources cover 5 and 6 in only as inlet and fitting facts. Oneida says its 4/5-inch Super Dust Deputy models include 4-inch reducer adapters for the inlet and outlet, and its 6-inch models have ports sized for crimped ductwork fittings.[12] The W1685 inlet Y above is the other. We list no 5 or 6 in hose because no maker page we verified documents one.
How to choose
- Read your collector's inlet from its maker, for your machine's version.
- Buy hose sold by inside diameter in that size, long enough for the run, with its spiral hand stated.
- Buy clamps for that hose's outside diameter and hand.
Picks that fit3 products
For a 4 in inlet, choose POWERTEC's 70111 (4 in x 10 ft, hose only) for a short run or the 70143 (4 in x 20 ft, hose only) for a longer one; POWERTEC lists both as left-hand spiral, so use left-hand or plain clamps.
More on choosing
Choose Rockler's Dust Right 4 in expandable hose when one hose has to reach several machines, and pick the length version on the listing that covers your run. None of these comes with clamps or cuffs. On Amazon, check that 'Ships from / Sold by' shows Amazon.com or the brand.

Guides
- Anti-static, dissipative and conductive hose: reading the claimsHelps you read a hose maker's static claim for what it says, without mistaking it for a safety rating.
- Choosing 4 in dust-collector hoseGives you a checklist for a 4 in collector hose: inside diameter, length, spiral hand, wall, vacuum rating and bend radius.

- Dust hose length and diameter: what the evidence showsTells you what is and is not known about how hose length and diameter affect a collector or shop vac, so you do not buy on invented numbers.
Shortlists
- 4 in dust-collector hoses with stated ends and wallHelps you pick 4 in collector hose whose maker states the inside diameter, length, wall and spiral hand, so fittings and clamps match it.
Tools
- Vacuum and collector inlet finderShows the inlet size, layout and supplied inlet parts each maker states for its collector or extractor, so you buy hose and fittings for the inlet you actually have.
Common questions
What is the difference between anti-static and conductive 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
Does an anti-static hose stop shocks?
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
Do I need to ground my dust collection hose?
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
Is a wire-reinforced hose grounded?
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
What 4-inch hose fits my collector?
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
What is a left-hand spiral 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
Does a 4-inch hose fit a 4-inch PVC pipe?
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
What do vacuum rating and bend radius mean?
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
Questions
What hose fits a 1 HP collector?
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.[1][2]
Is 6-inch hose better?
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.
What is an inlet Y?
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.[4]
Does anti-static hose make a collector safe?
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.[10]
