Abstract
The thread protector formed of a wire wound to form a helical portion having a proximal end, a distal end, a thread side, a protected side disposed at a protected diameter. The thread protector adapted to threadably engage the inside threads of a threaded inlet such as a clean-out used in piping systems defining a threaded passageway. The thread side disposed on a flank of the inside thread. The protected diameter smaller than the minor diameter of the threaded inlet whereby a protected passageway is formed along the protected side of the helical portion. The protected side spaced from a peak of the inside thread.
Claims6
A thread protector for use with a clean-out, the clean-out comprising an input, an output and an access opening, the access opening comprising threads surrounding a passageway, the passageway comprising a minor diameter, the thread protector comprising:
- a body, the body comprising a helical portion, a proximal end and a distal end, the helical portion comprising a wire wound into a helix shape, the helix shape extending from the proximal end to the distal end, the helical portion comprising a thread side and a tool side, the thread side disposed at an outer diameter, the outer diameter larger than the minor diameter;
- and
- a handle, the handle on the proximal end.
A thread protector comprising:
- a clean out, the clean out comprising an input, an output, an interior and an access opening, the access opening comprising an outer lip, and a passageway, the passageway comprising a threaded wall comprising a thread extending from the outer lip to the interior, the passageway in fluid communication with the interior, the thread comprising a thread depth, a peak, a root and a flank, the thread disposed around the passageway from the outer lip to the interior, the root on the cleanout, the peak extending inward from the root, the flank disposed between the root and the peak, the flank comprising a flank length;
- a body, the body comprising a helix portion comprising a wire wound to form a hollow core, a distal end and a proximal end, the wire wound in a helix shape having a tool diameter, the wire disposed on the flank, the hollow core extending from the outer lip to the interior, the wire comprising a wire diameter, the wire diameter smaller than the thread depth;
- and
- a handle, the handle on the proximal end.
