ASME B16.11 Threaded Half Coupling

what is a half coupling?

A half coupling is a very short piece of pipe or tube that is used to branch off a larger pipe or vessel into a smaller pipe. It lets you connect two pipes or tubes with an end that has a socket or threads. It only has one end with a socket or thread. Another end will be welded or fastened to the pipe.
