Abstract
Abstract A self-adjusting wear resistant seal assembly is provided for a cable rod slidably positioned within a cable conduit. A continuous polyethylene collar is radially compressed in close clearance around the rod by an elastomeric seal which embraces the end portion of the conduit and the collar and holds a flange on the collar against the end portion of the conduit. An integral lip on the seal engages the rod to provide a redundant seal. Corresponding serrations on the conduit and seal cooperate to secure the seal to the rod. A tapered lip may also be provided on the collar for engagement with the rod.
