Tube and cylindrical surface sealing apparatus

摘要

A fluid-tight sealing apparatus for sealing a tube to a cylindrical surface while subjected to axial, rotational and angular misalignments comprising a metallic, resilient sealing member on the tube having a ring portion with a curved surface for contacting the cylindrical surface and for forming a fluid-tight seal by means of an interference fit therebetween. The cylindrical surface can be the interior surface of a bore with the sealing member including a frustoconical portion having the ring portion at the larger end thereof and fitting into the cylindrical bore. The cylindrical surface can be the exterior surface of a conduit with the sealing member including a frustoconical portion having the ring portion at the smaller end thereof and fitting around the cylindrical conduit.
