The 3/4 in. Female x Female 500 PSI Check Valve with Viton (#46564V) is a 500 PSI rated brass check valve with a Viton (FKM) seal, designed for high-pressure shutoff and backflow prevention where fuels, oils, or hydrocarbons would degrade a standard Buna-N seat. Female NPT x Female NPT connections install directly inline with standard pipe threads.

Common Applications
Specified for high-pressure water supply, hydraulic return lines, compressed air, and industrial process piping where standard 150 PSI check valves are insufficient. 500 PSI rating suits pumped systems, booster pumps, and pressure-boosted water lines. Also suited to fuel and hydrocarbon transfer lines where Buna-N would degrade.
