Pressure washer spray gun for high-pressure cleaning
The Zoro Select MV925-LANCE spray gun handles up to 4500 psi and 8 gpm for demanding pressure washing tasks. Its 43-3/4 in lance provides extended reach on jobs that require distance from the spray zone. Brass and plastic construction resists corrosion from water and cleaning chemicals. The gun is built for use with compatible pressure washers.
Practical limits of the 4500 psi and 8 gpm rating
Maximum fluid temperature is 140 degrees F, so the gun must not be used with hotter water sources. Inlet and outlet threads are fixed at 3/8 in FNPT and 1/4 in FNPT, limiting direct hose and nozzle choices. Exceeding the rated pressure or flow can damage internal seals and create safety hazards. The gun is restricted only by its own pressure and temperature ceiling.
Installation and common pitfalls
Thread the inlet onto the pressure washer hose and the outlet onto the lance or nozzle using the specified FNPT sizes. Apply thread sealant to prevent leaks at the connections. A frequent issue is cross-threading the brass fittings during assembly, which ruins the seal. Another common problem is operating above 140 degrees F, which softens plastic components and leads to premature failure.

Questions about this item
Should I choose the 43-3/4 in lance or a shorter version for my pressure washer?
The 43-3/4 in length gives extra reach for high or distant surfaces. If you work in tight bays or prefer a lighter gun, a shorter lance may handle better.
What does the 4500 psi rating mean when I am actually washing?
It is the maximum pressure the gun can withstand. Your washer's pump determines the working pressure; the gun will not increase it beyond what the pump delivers.
How do the 3/8 in FNPT inlet and 1/4 in FNPT outlet affect what I can connect?
The 3/8 in FNPT inlet fits common high-pressure hoses, while the 1/4 in FNPT outlet accepts standard quick-connect nozzles and extensions.
