1/4" MNPT 2,000PSI 62.7°C / 145°F Thermal Valve

Essential Safety Component for Pressure Washer Systems The 1/4" MNPT 2,000 PSI 62.7°C / 145°F Thermal Valve is an essential safety feature designed to protect your pressure washer pump from overheating. Installed directly on the pump outlet or bypass line, this thermal relief valve automatically releases hot water when temperatures reach 62.7°C (145°F), allowing cool water to flow in and prevent damage caused by heat buildup during low-flow or bypass operation. Protects Your Equipment from Overheating When water recirculates inside a pressure washer pump during standby mode, temperatures can rise rapidly. This brass thermal valve ensures your system remains safe by venting overheated water once it reaches the set temperature threshold. The simple, automatic function eliminates the risk of thermal expansion damage, extending the lifespan of your pump, seals, and internal components. Built for Strength and Reliability Constructed from high-quality brass and stainless steel components, this valve is built to withstand pressures up to 2,000 PSI and continuous exposure to hot water. The durable materials resist corrosion and wear, ensuring long-term reliability in both residential and commercial cleaning applications. The 1/4" MNPT male threads offer secure, leak-free installation compatible with most standard pump outlets and fittings. Easy Installation and Maintenance Compact and easy to install, the 1/4" MNPT 2,000 PSI Thermal Valve integrates seamlessly into existing systems without additional tools. It automatically resets once the water cools, allowing continuous protection without manual intervention or downtime.
