Campbell Hausfeld CV221503SJ Check Valve Kit With Fittings

Campbell Hausfeld CV221503SJ Check Valve Kit with Fittings is an OEM replacement package built around the CV221503SJ check valve assembly and including the necessary fittings for installation on Campbell Hausfeld compressors. The check valve is designed to allow pressurized air to flow from the pump into the tank while preventing backflow into the pump, a function that helps maintain tank pressure and protect the pump from reverse flow. This kit is referenced in catalogs as compatible with Campbell Hausfeld WL503502 air compressors, making it a targeted remedy for that model’s valve wear or leaks. Contents are intended to replace a worn or failing valve assembly and its fittings, restoring one-way airflow and steady tank pressure without altering other components of the system. The CV221503SJ designation is an OEM part number used across Campbell Hausfeld repair catalogs and third-party retailers, ensuring you’re obtaining the correct replacement valve designed to fit Campbell Hausfeld equipment.
