How to Choose a Reducer Coupling

A reducer coupling joins two different pipe sizes in-line, so you can step a run down without forcing a mismatched fit. Schedule 40 Dura PVC, slip × slip.

Common reductions in stock are ¾″ × ½″, 1″ × ¾″ and 1″ × ½″ — match the larger end to your existing pipe and the smaller end to the branch. For a same-size joint, use a standard coupling. Available each or in bulk.
