Campbell Hausfeld CV221502SJ CV221502AJ Check Valve

Campbell Hausfeld CV221502SJ and CV221502AJ are OEM check valves with fittings designed for Campbell Hausfeld air compressors. They are installed in the discharge line between the pump head and the storage tank, allowing compressed air to flow into the tank while preventing backflow toward the pump. Retail listings describe CV221502SJ and CV221502AJ as interchangeable “check valve with fitting” components compatible with Campbell Hausfeld equipment, and they appear in manuals and catalogs tied to Campbell Hausfeld vertical and portable models that reference these part numbers. This one-way valve is a critical component for maintaining tank pressure and protecting the pump from backflow-induced wear. Replacement parts bearing CV221502SJ or CV221502AJ are sold as direct OEM replacements to ensure proper fit, compatibility, and reliable operation within Campbell Hausfeld assemblies.
