  • Method and apparatus for protecting pipe threads
    Patent number: 4239062
    Abstract: A pipe thread connector of resilient deformable material has a sleeve or tubular shape with radial ribs projecting from the sleeve. The protector is driven upon the threads of the pipe and the geometric configuration of the sleeve changes because the sleeve is bent between the ribs. This bending keeps the ribs in tight resilient contact with the threads.
