The old gun starts to stick while washing the car, and the spray fans out in a ragged pattern instead of a clean sheet. Before ordering a whole new washer, it helps to know the pressure washer gun parts that wear out: the trigger gun, the wand, the nozzle tips and the small fittings between them can each be replaced on their own.

Pressure Washer Gun Parts: What Each Part Does
A pressure washer gun is a small set of parts that work together: the trigger gun opens and shuts the water, the wand sets the reach, the nozzle tip sets the spray angle, and the fittings and O-rings keep the joints sealed. When one part wears out, replacing it can restore the spray.
The trigger gun is the handle you hold, with the trigger that starts and stops the spray and a lock that stops it from moving by accident. Wear eye protection whenever the washer runs, and never point the spray at people, pets or yourself.
Keep electric pressure washers on a GFCI outlet, never point the wand at people or pets, wear eye protection with polishers and chemicals, and read the label before mixing any cleaning products. Read our Safety Disclaimer.
The wand, also called the lance, is the tube between the gun and the nozzle tip, and its length sets how far you stand from the surface. The guns here change length: the Sooprinse gun changes between 12, 26 and 42 inches, the M MINGLE gun changes between 40, 25 and 8.8 inch lengths, and the FIXFANS kit changes between 37.4, 21.7 and 7.1 inches.
Nozzle tips set the spray angle, and the M MINGLE, Sooprinse and FIXFANS guns each come with 5 tips in 0, 15, 25, 40 and 65 degree angles. A narrow angle concentrates the jet on stubborn grime on hard surfaces, while a wide angle spreads the spray for gentler rinsing; the 65 degree tip is the soap tip for applying detergent.
Fittings decide whether a new gun connects to your hose at all. Most guns here use a M22 thread in 14mm or 15mm, and the M22 thread measures 22mm, so measure the fitting with a vernier caliper before ordering. A M22 14mm hose connects directly, while a M22 15mm hose needs a brass coupler or a convert fitting. The 1/4 inch quick connect takes nozzle tips, foam cannons and surface cleaners. O-rings are the small rubber seals inside each joint, and the FIXFANS kit includes 5 in the box.

FAQ: garage tools
What parts make up a pressure washer gun?
A pressure washer gun is made of a trigger gun, a wand, nozzle tips, fittings and O-rings: the gun holds the trigger and lock, the wand sets the reach, the tips set the spray angle, and the fittings and O-rings seal the joints.
Which fitting does a pressure washer hose use?
Measure the hose coupler with a vernier caliper: a 14mm coupler takes a M22 14mm gun directly, a 15mm coupler needs a brass coupler or a convert fitting, and the M22 thread measures 22mm. Garden hoses do not fit, since these guns use a M22 thread.
What do the nozzle tip angles mean?
The nozzle tips in these kits come in 0, 15, 25, 40 and 65 degree angles. A 0 degree tip throws a straight jet for stubborn grime on hard surfaces, while the 65 degree tip is the soap tip for applying detergent.
Can one gun fit a gas and an electric pressure washer?
Yes, when the fitting matches: the M MINGLE and FIXFANS guns fit gas and electric washers with a M22 fitting, and the FIXFANS kit is rated for 5000 PSI and 8 GPM.
