ABSTRACT:
A protector for a threaded end section of a cylindrical part, such as pipe, has a tubular body having a plurality of flexible ribs projecting from a wall of the body. The ribs, in an unflexed condition, extend at an acute angle in a forward direction toward the pipe upon which the protector is placed on the threaded end section of the pipe. The body is disposed in space telescoped confronting relation to the threaded end section of the pipe to preclude circumferential and radial destructive stress between the body and the threaded end of the pipe. In one embodiment the ribs comprise first ribs engageable with the threaded end section of the pipe and second ribs located adjacent the first ribs in holding engagement with the threaded end section of the pipe.
