Use this General Pump, 3/8″ Thermal Relief Valve on nearly any brand of pressure washer pump such as Hotsy, Landa, Karcher, Alkota and other brands.

This pressure washer pump protector is designed to open when the temperature within the pump manifold reaches 145 degrees F, allowing some of the hot water to exit the pump head, and allowing cool water to enter. This pump seal saver prevents damage to pressure washer pump seals and valves, which can result in loss of pressure.

Plumbs easily into the inlet of many pressure washer pumps.
