ABSTRACT:
Mating members, one rotating, the other stationary, each have grooves in facing annular surfaces for receiving rings, some of which rings carry seal strips and other of these rings define lands for engagement by the seal strips. All of the rings are held in place by elongated fasteners extending through aligned openings in the seal rings and in the land defining rings respectively, which fasteners serve to hold these rings in the associated grooves.
