ABSTRACT:
A hydraulic snubber device arranged for facilitated servicing of a secondary seal thereof. A bushing removably mounted to the head of the device cooperates therewith to retain a split annular seal element in sealed association with a piston rod extending outwardly therethrough. A bushing is movable on the rod sufficiently to expose the seal for selective removal and installation when desired. The snubber is adapted for use in a radioactive environment wherein the split seal may suffer degradation such as from radiation and permits the replacement of the seal without disconnecting elements connected to the end of the piston rod so as to provide minimum downtime in servicing the installation.
