Abstract
A fitting for a fluid pressure conduit. The fitting includes a coupling body having a substantially axisymmetrical inside surface for engaging an outside surface of the fluid pressure conduit. The inside surface has at least one substantially axisymmetrical seal formed as at least one axisymmetrical ridge on the inside surface of the coupling body. There is at least one seal land on an outside surface of the coupling body adjacent the substantially axisymmetrical seal(s). There are a plurality of anti-torsion ridges on the inside surface of the coupling body, the anti-torsion ridges having friction surfaces for resisting torsion between the fitting and the fluid pressure conduit. Furthermore, there is at least one torsion land formed on the outside surface of the coupling body adjacent the torsion ridges. The fitting also includes a ring for fitting over the coupling body, the ring being for engaging the seal land(s) to force the seal(s) into engagement with the outside surface of the fluid conduit, the ring further being for engaging the torsion land(s) to force the plurality of anti-torsion ridges into engagement with the fluid pressure conduit.
