This thermal relief valve is a genuine part produced by the original manufacturer for DeWALT pressure washers. The valve connects to the pump and protects it from overheating. If the pump gets too hot this valve will pop out to release extra pressure, and prevent excessive damage to the pump. It is an identical replacement for a damaged or a missing component that was installed on a new unit. Note, one durable metal thermal relief valve is included. To replace it you will need an adjustable wrench. Make sure to release the pressure from the tank before starting the repair.
