Identifying and buying
Find your exact model number, read its documented connections and rated output, check each part's ends and rating, then the seller, returns, duties and recalls.

Short answer
Identify first, then buy. Find your pressure washer's exact model number, read its documented connections and rated output, and check that the part's two ends and its rating match. Only then look at who sells it, what returns and import costs apply, and whether your machine is under a recall.
What this topic covers
This topic is the checklist behind every other page on the site. A hose, gun, adapter or nozzle has to connect at both ends and be rated for your machine. The listing alone rarely tells you both, so the work starts with your own machine's documents.
The decisions, in order
1. Find your exact model number. Everything else hangs on it. RYOBI's support site looks up manuals, parts and repair information by the tool's model number, found at the top left of the label.[1] Other makers use their own labels; the model number, not the brand or the headline PSI, decides which manual applies.
2. Read its documented connections and rated output. The manual or parts list names the fitting at each joint, when it names one. Where it does not, identify the fitting itself. AR Blue Clean recommends identifying an M22 fitting by measuring the inner bore of the male connection or by checking the product documentation for the internal diameter.[2] Read output carefully too. Greenworks lists its GPW2303A in Canada at a maximum flow of 2.3 GPM and a rated flow of 1.2 GPM, so the headline PSI and GPM are not one operating point.[3] The identify guide and the max vs rated guide go through both.
3. Check the part's ends and rating. A part needs the right standard and gender on each end, and a rating at or above your machine's output. Cat Pumps advises that a high-pressure system is only as strong as its weakest component.[4] A higher rating is a limit, not a fit.
4. Check the seller. Some makers link the retailers they sell through. SIMPSON's own Monster Hose 41028 page links to Amazon.com as one of its online retailers, alongside Lowe's, Tractor Supply, Grainger, Zoro and others.[5] A maker link to an Amazon product page still does not tell you which seller wins the offer, so check "Ships from / Sold by" at checkout. The Amazon and AliExpress buying guide covers sellers in detail.
5. Returns, duties and recalls. AliExpress's Free Returns terms apply only to items showing a Free Returns icon and to registered buyers who meet its requirements.[6] Canada's border agency says online purchases shipped from another country may be subject to duties, taxes and administrative fees.[7] Recalls are model- and serial-specific: CPSC's RYOBI recall 25-452 covers models RY142300, RY142300VNM and RY142711VNM within specified serial-number ranges.[8]
Safety standards on machines
A safety mark concerns the machine, not an aftermarket hose or adapter. UL 1776, High-Pressure Cleaning Machines, covers portable, stationary and fixed high-pressure cleaning machines and portable rechargeable battery-powered machines.[9] In Canada, Health Canada advises not buying plug-in electrical products online without a Canadian electrical certification mark such as CSA, cUL or cETL.[10] The recalls and safety standards guide explains how to check a mark.

More on choosing
Choose the Monster Hose 41028 for cold water (up to 140°F) or the Armor Hose 41114 if every other part of your system is rated for hot water (the hose is rated to 250°F). On Amazon, check that 'Ships from / Sold by' shows Amazon.com or SIMPSON.

Common questions
Do I pay duty on pressure washer parts from the US or China?
You may. The Canada Border Services Agency says online purchases may ship from another country and may be subject to duties, taxes and administrative fees. Some courier goods are exempt at low values, with conditions. More in Buying pressure washer parts in Canada
Who charges the brokerage fee?
The courier or customs broker, not the government. CBSA says courier and broker clearance fees are a private business-to-consumer charge outside its control and separate from duties and taxes. More in Buying pressure washer parts in Canada
What certification mark should a pressure washer have in Canada?
For a plug-in machine, Health Canada advises not buying plug-in electrical products online without a Canadian electrical certification mark such as CSA, cUL or cETL. That advice is about powered products, not hoses or fittings. More in Buying pressure washer parts in Canada
If I return a part to a US seller, do I get the duty back?
Possibly the duty and tax, never the brokerage. CBSA lists goods returned to a seller outside Canada as a possible reason for a duty and tax refund, with conditions, but says it cannot refund brokerage or courier fees. More in Buying pressure washer parts in Canada
Are pressure washer parts on AliExpress genuine?
Check the store against the maker's own site. On the maker pages we read for SIMPSON, Flexzilla, ProPulse, MTM Hydro, Suttner, McKillans, YAMATIC and M MINGLE, we found no link to an AliExpress store, which is not proof either way. MJJC's Where to Buy page points to distributors and mentions neither Amazon nor AliExpress. More in Buying hoses, guns and adapters on Amazon and AliExpress
Can I return a pressure washer adapter bought on AliExpress?
Only if the listing shows AliExpress's Free Returns icon and you meet its terms. The window depends on the seller's location, and the item must meet AliExpress's intactness standards. More in Buying hoses, guns and adapters on Amazon and AliExpress
Does a third-party part void my warranty?
It can affect coverage. Champion's two-year limited warranty for the 100384, for example, excludes accessory parts such as hoses, nozzles, wands and guns, and problems caused by parts that are not original Champion parts. Read your own machine's warranty. More in Buying hoses, guns and adapters on Amazon and AliExpress
What is Amazon's return window for these parts?
We could not read Amazon's return policy page for these parts, so we do not state one. Check the return terms shown on the listing and at checkout. More in Buying hoses, guns and adapters on Amazon and AliExpress
Questions
How do I find my pressure washer's model number?
On the machine's label. RYOBI's support site, for example, looks up manuals, parts and repair information by the model number found at the top left of the label. With it you can read the manual for your exact model.[1]
Does a part rated 4,000 PSI work on a 3,000 PSI machine?
A higher rating is a limit, not a fit. The part also has to connect: its ends must match your hose, gun or wand. Cat Pumps advises that a system is only as strong as its weakest component, so check every part in the line.[4]
Are AliExpress pressure washer parts returnable?
Only some. AliExpress's Free Returns terms apply only to items showing a Free Returns icon and to registered buyers who meet its requirements, not to every item. Check the listing before you order.[6]
Is my pressure washer recalled?
Check CPSC (US) or Health Canada by your exact model and serial number. CPSC's RYOBI recall 25-452, for example, covers three models within specified serial ranges. The recalls guide explains how to check.[8]
