Gardner Denver Champion P03590A In Tank Check Valve is a 1-1/4 inch FNPT x 1-1/4 inch MNPT valve designed for in-tank installation in Champion/Gardner Denver air compressors. It prevents backflow from the tank into the discharge line and helps maintain tank pressure when the compressor stops. The valve features a female 1-1/4" NPT connection on one end and a male 1-1/4" NPT connection on the other, enabling straightforward plumbing in tank setups. The recommended mounting orientation is vertical for best performance.
