Extension wands and lances
Choose a pressure washer extension wand by the gun outlet it joins, its own inlet and outlet, its PSI and GPM rating, its length and the maker's model list.

Short answer
Choose a pressure washer extension wand by its two connections and its rating. Its inlet has to take your gun's outlet, its outlet has to take your nozzles, and its PSI and GPM rating has to be at or above your machine's output. Then check its length and whether the maker lists your model, and read the handling rules in its manual before you use it.
What this topic covers
A lance or wand is the rigid tube between the gun and the nozzle. This topic covers replacement lances, longer and telescoping wands, and angled and gutter wands. It covers the connections, ratings and the makers' handling rules.
The decisions, in order
1. The gun outlet. Start from what your gun ends in. SIMPSON's MSH3125 parts list shows a 16 in lance with a 1/4 in quick-connect outlet and an M22 male end, part 7103550.[1] A replacement for that lance needs the same M22 end to meet the gun.
2. The wand's inlet and outlet. Read both ends on the maker's page. DEWALT's DXPA31SW is a 31 in spray wand that fits standard M22 spray-gun connections and has a 1/4 in quick-connect outlet for tips.[2] Westinghouse's PWEXT manual lists a male M22-14 inlet, a 3/8 in quick plug on the gun inlet with two M22 male brass fittings in the box, and a 1/4 in quick-connect outlet for nozzles.[3] RYOBI's 18 ft telescoping pole, read on RYOBI's Canadian site, comes with a 3/8 in quick-connect to M22 adaptor.[4]
3. PSI and GPM rating. The wand's rating has to cover your machine. DEWALT rates the DXPA31SW up to 4,500 PSI, for cold water only.[2] Westinghouse gives the PWEXT a 4,000 PSI maximum and a 1/4 in quick-connect outlet.[5] RYOBI lists its pole for washers up to 4,200 PSI.[4] Westinghouse's manual says never to exceed the wand's rated pressure or volume and never to use it with unapproved accessories.[3]
4. Length and the maker's model list. Length figures can differ even within one maker. Westinghouse's PWEXT manual says the wand is adjustable from 6 to 9 ft, while its product page lists 10.5 ft assembled.[3][5] Westinghouse lists the PWEXT as compatible with its ePX2000, ePX3050, ePX3100, ePX3100v, ePX3500, WPX2300e, WPX2700e, WPX3000e, WPX3200e, WPX3400e, WPX2700, WPX3200, WPX3400, WPX3600 and WPX3800 washers.[5] A list like that is the strongest fit statement a maker gives.
5. Handling rules. A long wand changes how the spray behaves in your hands. Westinghouse's manual says never to extend or retract the wand, or change nozzles or accessories, while spraying or under pressure; stop the equipment and relieve pressure first.[3] It also says to keep proper balance and control of the extended wand.[3] RYOBI's pole ships with a support strap.[4] The wand safety guide collects the makers' warnings.

Common questions
Can I use a pressure washer on a ladder?
The manuals say no. Westinghouse's PWEXT manual says never to use the wand on ladders or scaffolding, and Generac's manual warns not to use the machine or any of its components on elevated surfaces because of fall risk. More in Extension wands: ladders, power lines and pressure-off changes
How far from power lines should a pressure washer wand be?
Westinghouse's PWEXT manual says never to use the extension wand near power lines and to make sure no power lines or electrical sources are within 10 feet of the lance at any time. It also says the wand is not insulated. More in Extension wands: ladders, power lines and pressure-off changes
Can I change nozzles while the machine is running?
No. Westinghouse's PWEXT manual says never to extend or retract the wand, or change nozzles or accessories, while spraying or under pressure; stop the equipment and relieve pressure first. More in Extension wands: ladders, power lines and pressure-off changes
Does a long wand need a strap?
RYOBI's Canadian listing says its 18 ft RY31EP26VNM pole comes with a support strap. Westinghouse's PWEXT manual tells users to keep proper balance and control of the extended wand. Follow your own wand's manual. More in Extension wands: ladders, power lines and pressure-off changes
Do extension wands fit all pressure washers?
No. Westinghouse, for example, lists the specific Westinghouse models its PWEXT wand is compatible with. Check the wand's inlet against your gun's outlet and its rating against your machine. More in Extension wands and lances: connections, ratings and reach
What connection does an extension wand use?
Usually an M22 male inlet into the gun and a 1/4 in quick-connect outlet for nozzles. SIMPSON's MSH3125 lance and DEWALT's DXPA31SW both use that pairing, and Westinghouse's PWEXT has a male M22-14 inlet. More in Extension wands and lances: connections, ratings and reach
How long is the Westinghouse extension wand?
Westinghouse's own sources differ. The PWEXT manual says the wand is adjustable from 6 to 9 feet; the product page lists 10.5 ft assembled. More in Extension wands and lances: connections, ratings and reach
Can I use a wand rated lower than my pressure washer?
No. Westinghouse's PWEXT manual says never to exceed the wand's rated pressure or volume, and Cat Pumps says a system is only as strong as its weakest component. More in Extension wands and lances: connections, ratings and reach
Questions
Will an extension wand fit my pressure washer?
Only if its inlet matches your gun's outlet and its rating covers your machine. Westinghouse lists the PWEXT for named ePX and WPX models, with a male M22-14 inlet and a 1/4 in quick-connect outlet. Check your model against the maker's list.[5][3]
How long are extension wands?
It depends on the maker, and sources can disagree. Westinghouse's PWEXT manual says the wand is adjustable from 6 to 9 ft, while its product page lists 10.5 ft assembled. DEWALT's DXPA31SW is a 31 in wand, and RYOBI's Canadian site lists an 18 ft telescoping pole.[3][5][2][4]
