Campbell Hausfeld CV221503AJ Check Valve Kit With Barb

The Campbell Hausfeld CV221503AJ Check Valve Kit with Barb is an OEM replacement part for Campbell Hausfeld air compressors that use the CV221503AJ check valve configuration. The kit includes a one-way check valve with barb fittings to connect hoses or tubing in the compressor’s air path, enabling unidirectional airflow and preventing backflow from the tank or downstream lines into the pump. Replacing a worn or leaking check valve helps restore consistent pressure, improve efficiency, and protect pump seals from reverse-flow wear. The CV221503AJ designation is listed in Campbell Hausfeld parts catalogs as the dedicated check valve kit with barb connections for compatible models, providing a straightforward repair option for maintenance and service tasks.
