ABSTRACT:
In a sealing arrangement between a tubular housing (2) and a rod (1) in a rail vehicle slack adjuster, a cup (3) is movable with the rod and extends along the rod over the free end of the housing. A sealing arrangement (6-9) is in sealing engagement with the housing (2). It comprises flange-like portions (6', 7), extending into close proximity with the inner wall of the cup for forming a labyrinth seal, and a sealing lip (9') in sealing contact with the end of the cup for preventing the intrusion of water and the like in the cup.
