Abstract: A check valve assembly includes multiple components. for coupling together first and second pipes, and has multiple components, including a check valve, a check valve housing, a check valve body adapter and a locking ring. A mating surface coupling between a check valve body adapter inlet mating surface and a check valve housing outlet mating surface together with a flange coupling between a check valve body adapter inlet coupling flange and a locking ring inwardly extending and circumferentially extending flange combines to form a check valve assembly union U that allows the multiple components of the check valve assembly to freely orient and align when the check valve assembly is threaded and coupled to the first and second pipes.
