ABSTRACT:
A sealing nut has an annular heat stabilized nylon sealing insert retained within a recess in a metallic nut body by a coined collar on the nut body. The sealing insert is initially formed symmetrical about a transverse median plane to enable bidirectional assembly into the nut body recess, and undergoes dynamic preloading when the collar is coined onto the periphery of the insert. When installed onto a threaded shaft extending from a bearing surface so that the coined collar is torqued against the bearing surface, the sealing insert forms a fluid-tight seal between the threaded shaft and a threaded bore in the bearing surface through which the threaded shaft extends. The nut body and sealing insert facilitate reduced manufacturing costs while enabling re-use without significant loss in sealing properties.
