Industrial CV221500AJ In-Tank Check Valve Brass

CV221500AJ Super Check In-Tank Check Valve is a brass, in-tank valve from Campbell Hausfeld designed to be installed inside the air compressor tank to prevent backflow from the tank into the pump, a failure mode that can compromise pressure and pump life. It features a 1/2 in compression inlet and a 1/2 in MNPT outlet, providing a compact combination of connection types that suits Campbell Hausfeld models and other systems using these sizes. The all-brass body offers durability in typical compressor environments, and this model is marketed as a direct replacement part for Campbell Hausfeld equipment to help maintain tank pressure and reliable startup when the original check valve fails. Commonly used in shop and portable compressors, CV221500AJ delivers a straightforward, one-way flow path essential for sustained compressor performance.
