Abstract
A self locking reusable rod seal includes a case hardened stamped frustro-conical member comprising a C-shaped section from which two like opposing arcuate segments are cantilevered. The member is located and secured for axial displacement in a frustro-conical bore of a case hardened steel housing. The segments have axially spaced ridges, the end most ones of which grip a rod in the bore thereof, the rod axially displacing the member when the rod is displaced in opposite directions relative to the housing. The rod has circumferential axially spaced grooves. The member ridges engage the grooves so as to be pulled by the axial displacement of the rod. The ridges and grooves are resiliently engaged and when the member is displaced toward one end of the housing bore, the ridges disengage and when the member is displaced toward the other end of the bore, the ridges are wedged against the rod grooves. The rod has a head at one end which with the seal lock a hasp therebetween by limiting displacement of the rod toward the one housing bore end.
