The Campbell Hausfeld CV201400AJ check valve is an aluminum-bodied replacement part designed for Campbell Hausfeld air compressors and Craftsman CV-14 units, and it ships with the gasket included. As a one-way valve, it allows air to flow from the pump to the tank while preventing backflow, helping to maintain tank pressure and protect the pump components. In replacement-part catalogs, the CV201400SJ is listed as replacing the aluminum CV201400AJ and the CV-14, confirming its place within the same CV-series valve family and compatibility with legacy Campbell Hausfeld/Craftsman equipment.
