Overview

This is a complete plumbing kit built around the VRT3-310EZ pump-mounted unloader with external bypass, and it fits any pressure washer pump rated up to 4200 PSI with a 1/2" inlet and 3/8" outlet. It gives you everything needed to plumb the unloader and bypass onto the pump: the unloader, a hex nipple, hose barbs, a 45° elbow, bypass hose, thermal relief valve, a garden-hose inlet with bypass port, a 50 mesh inlet strainer, and a quick-connect plug. It's for anyone rebuilding a pump or replacing a worn unloader assembly on a machine in that PSI range.
