ABSTRACT:
A loosening tool for breaking loose tightened threads of a pipe coupling using a plurality of wrench type devices is provided that is simple to use, offers more breakage force than muscling alone, and is relatively safe and effective in its operation. The loosening tool includes a forward facing support jaw, a base bar that supports a corresponding rearward facing support jaw and an adjusting mechanism used to move the forward facing support jaw from a ready position to a loosened position such that the pipe coupling moves to a less tightened position.
