An integrated in-line tube and check valve assembly fabricated by end-form mandrel expanding an outlet end portion of deformable tube stock, such as metal, of nominal starting diameter, and concurrently end-forming a valve seat on the inside of the expanded tube section where it necks down and integrally joins the upstream nominal diameter portion of the tube. The fastening system includes a metal clip which is easily inserted and removed from a polymeric doghouse. The carrier is attached to a vertically-disposed wheel for rotating the carrier in a circular path.
