Vibrant Performance Pressure Relief Valves

Vibrant Performance pressure relief valves improve the serviceability of automotive fuel, oil, and coolant systems, by reducing fluid spillage when hoses are removed. When installed at the highest point in a coolant system or component, the pressure relief valve can be used as a bleeder to purge any unwanted air from the system/component. These components are constructed from 304 stainless steel and are black zinc plated. They are compatible with automotive fuel, oil and coolant systems and have been tested for low and high pressure sealing abilities up to 100 psi. The 1/8 in. NPT body design installs with a 7/16 in. wrench (thread tape recommended). Show Less
