This gun allows a constant trickle of water to pass through. This aids your pressure washer cooling because it allows a drip of cool inlet water into the pump when it is running but not being used. Another application is for outdoor uses where the flow of water will discourage freezing.
Rated for up to 5000 psi, 10.4 Gallons per minute and 300°. 3/8 FPT inlet and 1/4 FPT outlet.
