Shortlist · Extension wands and lances
Extension wands and lances with both ends and a rating stated
Extension wands and replacement lances whose makers state the gun-end and nozzle-end connections and a pressure rating: Westinghouse's PWEXT kit and two SIMPSON wands.

Short answer
Westinghouse's PWEXT kit states both ends, a 4,000 PSI maximum and a list of the Westinghouse machines it fits.[1] SIMPSON's 80149 (16 in) and 80479 (31 in) are single-length replacement wands whose connections and ratings SIMPSON states on its own pages. Match each end to your gun and nozzles, and the rating to your machine.
How we chose
A wand is on this list only if:
- Its maker states both ends. DEWALT's DXPA31SW, for example, is a 31 in wand that fits standard M22 spray-gun connections and has a 1/4 in quick-connect outlet for tips.[2] SIMPSON's MSH3125 parts list shows a 16 in lance with a 1/4 in quick-connect outlet and an M22 male end.[3]
- Its maker states a pressure rating. Westinghouse gives the PWEXT a 4,000 PSI maximum.[1] RYOBI lists its 18 ft telescoping pole for washers up to 4,200 PSI on its Canadian site.[4] Westinghouse's manual says never to exceed the wand's rated pressure or volume.[5]
- Its length is stated, and we show where makers disagree. Westinghouse's manual says the PWEXT is adjustable from 6 to 9 ft, while its product page lists 10.5 ft assembled.[5][1]
- It is an exact brand and model in our catalog, and its store button shows only after a US "Ships from / Sold by" check.
Three approved wands met this bar on 2026-10-16. Only the PWEXT's figures are in our verified fact register so far, so the SIMPSON entries describe their role and send you to SIMPSON's page for the numbers.

Questions
Will the Westinghouse PWEXT fit a non-Westinghouse machine?
Westinghouse's compatibility list names only its own ePX and WPX washers. Its page says it fits 'most' washers, but that does not establish fit for any specific other brand; check the inlet and rating against your gun and machine.[1]
How long is the PWEXT?
Westinghouse's manual says it is adjustable from 6 to 9 ft; its product page lists 10.5 ft assembled. We show both because the maker's own sources differ.[5][1]
Can I extend the wand while spraying?
No. Westinghouse's manual says never to extend or retract the wand, or change nozzles or accessories, while spraying or under pressure; stop and relieve pressure first.[5]
