The compression fitting wrench is specially designed for tightening the compression nuts in a compression fitting.
Regular wrenches can be used on compression fittings, however, since their jaws are not designed to connect to the compression fitting nut, they may not be as accurate and may slip on the nut when compared to using a compression fitting wrench.
Wrenches for compression fittings can be single ended or double ended.
What is a compression fitting?
A compression fitting is a set of two compression nuts, a swivel or fitting, and two compression rings (olives). It is used to connect two pieces of copper or plastic pipes during plumbing work.
