1/4" 4 PSI Drip-Free Arch/Tire Shine Diaphragm Check Valve

These 1/4" diaphragm check valves are used on multiple arches including the Presoak, Spot Free Rinse, and Drying Agent arches as well as the Tire Shine unit. They are used to prevent dripping from the arches and help control the measurement of detergent used. The nylon body makes for excellent corrosion, impact, and temperature resistance. Designed for 1/4" spray nozzles to screw into easily, these check valves have a 4 PSI cracking pressure with a Viton green seal.
