The Conrader CAC-Series is a serviceable in-tank check valve for compressed-air and pneumatic systems. It threads into the tank or receiver with the male NPT outlet seated inside, opening to allow flow in one direction and closing the instant flow stops or reverses — protecting the compressor pump from backflow. The compression-tube inlet connects directly to copper or aluminum discharge tubing.
