This is a genuine OEM replacement part that has been sourced directly from DeWalt. The thermal relief valve helps you operate you pressure washer safely. This part regulates the amount of pressure in the line at any given time. When the pressure in the line builds to a certain level the relief valve is pushed open and allows excess pressure to escape, rather than allowing it to build-up in the line. This replacement part is a safety mechanism that helps prevent serious damage to you or your equipment. This thermal valve relief is made of metal, and the threads have sealant on them to ensure airtight connection. The thermal valve relief is sold individually. You will need basic hand tools for installation.

This part is sourced from DeWalt and is a manufacturer approved replacement part for DeWalt Pressure washers. For full compatibility, please see the "Model Cross Reference List" below. This valve kit contains a complete set of check valves (3 inner valves and 3 outer valves), as well as the rubber o-rings needed for installation. These valves fit in the pump and work together to pressurize the water. If your pressure washer is unable to build pressure or has low pressure, it may be time to replace the valves. These valves are made out of plastic and metal, and each valve is approximately 0.5" in length. These valves are also referred to as Check Valves. There are 6 valves in each kit, which is enough to replace all the valves on your pressure washer.
