Coupling

Couplings are used to connect two segments of pipe. Typically, a pipe Coupling will have a threaded ID on either end. Pipes with threaded ends will be screwed into either side of the Coupling to create a longer run of pipe. Couplings can also be Socket Weld, with the square cut pipe ends fitting into sockets on either side of the Coupling and permanently welded in place. While it is possible to have a Coupling with one threaded and one socket end, it’s not common.

The Half Coupling is similar to the Coupling in that it connects two lengths of pipe. However, not only is it half of the size, but its threads run in only one direction and will only accept a threaded pipe on one side. The side that will not accept a thread is butted up against a steel body, typically another length of square-cut pipe, and welded in place.

A Reducing Coupling does exactly what its name implies: It reduces flow by joining a larger pipe to a smaller pipe. Like the standard Coupling and Half Coupling, the reducing variety is available with threaded and weld ends.
