Pressure Washer Wand / Lance Guide: Replacement & Telescoping
Choose a replacement, extension or telescoping pressure washer wand by the gun-side connection, nozzle-side connection, pressure and temperature ratings, and the reach needed for the job.
Two ends, two jobs
Spray gun → wand/lance inlet → rigid or telescoping tube → nozzle/accessory outlet. Identify both interfaces before choosing length or reach.

What the wand/lance has to match
Pressure washer wand, spray wand and lance mean nearly the same thing
Manufacturers use “wand,” “spray wand” and “lance” for the rigid high-pressure tube between the gun and nozzle. The naming difference is less important than the hardware at each end. For example, SIMPSON calls its 31-inch model a wand/lance and specifies an M22 inlet from the gun and a 1/4-inch quick-connect socket for the nozzle.
When replacing a wand, match the actual interface rather than searching only for the same noun printed on the original product.
Current fixed and telescoping wand examples
| Current example | Length / type | Pressure | Temperature | Gun-side | Nozzle-side |
|---|---|---|---|---|---|
| SIMPSON 80149 | 16" fixed | 3600 PSI | 140°F | M22 male | 1/4" QC socket |
| SIMPSON 80479 | 31" fixed | 4500 PSI | 140°F | M22 male | 1/4" QC socket |
| SIMPSON 80179 | 48" insulated | 5000 PSI | 212°F | 1/4" MNPT | 1/4" QC socket |
| SIMPSON 80470 | 6–18 ft telescoping | 4000 PSI / 8 GPM | 140°F | 3/8" QC plug; M22 QC adapter included | 1/4" QC socket via included extension wand |
Even within one manufacturer, gun-side connections differ by wand type. “Universal” in a product title still depends on the specified connection path and ratings.
Fixed replacement wand: start with the gun outlet
Many residential replacement wands use an M22 connection at the gun and a 1/4-inch quick-connect socket at the nozzle. That pattern is convenient because common spray tips and some attachments use a 1/4-inch QC plug, but it does not make every M22 gun/wand pair interchangeable.
If your gun uses a 1/4-inch threaded outlet, 3/8-inch QC, proprietary bayonet or another system, the wand must match that interface directly or through a correctly rated adapter. Use the Fittings & Quick Connects guide before adapting.
For model-specific wand and connection evidence, see Sun Joe parts, Generac parts and Troy-Bilt parts. Their documented paths differ, so do not transfer one brand's M22, quick-connect or bayonet assumptions to another.
Pressure washer extension wand and telescoping wand
Fixed extension wand
Adds a known amount of rigid reach and keeps a simple connection path. Current SIMPSON 16-inch and 31-inch wands are cold-water products with M22 gun-side and 1/4-inch QC nozzle-side connections.
Telescoping wand
Adds much more reach but introduces a longer, heavier assembly and specific operating instructions. SIMPSON's 80470 extends from 6 to 18 feet, is rated to 4000 PSI / 8 GPM and includes both a 3/8-inch QC plug and M22 threaded QC adapter for the hose-side connection.
Telescoping-wand safety matters more than maximum reach
SIMPSON's current 80470 instructions warn about overhead power lines, require operation from a permanent stable surface rather than ladders or chairs, and specify that at least 6 inches must remain inside each telescoping section for stability. The instructions also require the pressure washer to be shut down and depressurized before changing accessories.
Use the manufacturer manual for the exact telescoping wand you own; do not generalize one model's extension limit to another.
Cold-water vs. insulated hot-water wands
Wand temperature ratings can differ substantially. SIMPSON's 31-inch 80479 is a cold-water wand rated to 140°F, while the 48-inch insulated 80179 is documented to 212°F. The hot-water wand also changes the gun-side interface from M22 to 1/4-inch MNPT in the current catalog.
This is a useful reminder that choosing by length alone can produce the wrong part. Temperature class and connection type can change together.
Replacement-wand checklist
| Check | What to verify |
|---|---|
| Gun outlet | Exact connection family, size and gender; note any removable adapter. |
| Wand inlet | Must mate with the gun directly or via a rated documented adapter. |
| Nozzle/accessory outlet | Confirm 1/4-inch QC or the required alternative. |
| Pressure and temperature | Wand limits must cover the actual pressure-washer operating conditions. |
| Reach | Select fixed or telescoping length without compromising safe operating position. |
| Accessory requirements | Nozzle/surface-cleaner/other attachment still needs appropriate flow, pressure and connection. |
After the gun-side and nozzle-side connections are known
Compare replacement wands within the correct pressure, temperature and interface class. If your priority is long reach, verify the telescoping wand's connection path and operating limits separately rather than treating length as the only specification.

Frequently asked questions
Are pressure washer wands universal?
No. Many wands use common M22 gun-side connections and 1/4-inch quick-connect nozzle sockets, but other wands use threaded or quick-connect gun interfaces. Pressure and temperature ratings, length and proprietary systems also vary.
What is the difference between a pressure washer wand and lance?
The terms are often used interchangeably for the rigid tube between the spray gun and nozzle/accessory. Product naming varies by manufacturer, so compatibility should be based on the documented inlet, outlet, length and ratings rather than the word used in the title.
Can I use a telescoping wand on any pressure washer?
No. Match the hose/gun connection and the machine's pressure/flow to the telescoping wand's published limits. Follow the wand's safety instructions, including overhead power-line precautions and stable-ground operation.
What connection is normally used for pressure washer nozzles?
A 1/4-inch quick-connect socket is common at the nozzle end of many replacement wands. Current SIMPSON fixed and telescoping wand examples use 1/4-inch QC nozzle connections, but the exact wand and accessory must still be checked. See the nozzle guide for orifice sizing versus spray-angle selection.
Can I replace an M22 wand with a quick-connect wand?
Only if the gun-side interface is correctly converted with a suitably rated adapter or gun configuration. The nozzle-side connection, pressure, temperature and machine/accessory requirements must also remain compatible.
