Additional Info
A union is a pipe fitting designed for an easy connection and disconnection for future pipe maintenance and replacement. It is similar to the coupling but a coupling requires more work to disconnect and remove from the piping system. Unions feature a three-part configuration consisting of a male end, a hex nut and a female end.
