How do I know which quick disconnects work together?

First, they must be in the same series for connecting the coupling body and the coupling insert. All but the PLC and PMC series are interchangeable no matter what size the end connections are in the series. On the PLC series and PMC series, the flows have to match for them to connect.

A complete set comprises the coupling body and insert. The coupling body is the part with the release button, and the coupling insert is the part that inserts into the coupling body. These are sold separately, so you must purchase both for a complete coupling. Below is some general information on the quick disconnects that we offer:
