The PAI EM40630 is a check valve with one male port, one 3/8-inch P.T. female port, one 1/4-inch P.T. female port, and two 3/8-inch P.T. female ports. As heavy duty diesel truck parts, check valves ordinarily regulate flow through air systems by allowing passage in one direction and limiting reverse flow. The listed port sizes and configuration help match this component to the intended plumbing arrangement. Mack identifies 20QE2199 as the OEM reference.
