Abstract
A transition fitting for connecting plastic conduit to various elements of a fluid transfer system is provided which includes in combination a pressure deformable plastic conduit, rigid sleeve means inserted in one end of said plastic conduit in circumferential contact therewith, a pressure deformable rubbery resilient member extending around the conduit and sleeve in contact with said conduit, compression ring means extending around the conduit and sleeve having a radial face abutting one face of the resilient member and applying compressive pressure thereon, a radially expandable and contractible frusto-conical gripping member, said gripping member surrounding the conduit and sleeve and having a base portion engaging the other side of the compression ring, spaced surface engaging means on the gripper member in contact with the exterior of the conduit, a first body member surrounding the conduit and sleeve and confining the rubbery gasket against outward radial expansion, said body member and compression ring cooperating to reduce the axial thickness of the rubbery gasket to exert radial sealing pressure on the conduit, and a second body member surrounding the conduit and sleeve and having an internal frusto-conical surface mating with that of the gripping member, said first and second body members being axially movable relative to one another to reduce the distance between them to compress the rubbery gasket axially and radially inwardly and the gripping member radially inwardly against the conduit.
