First of all they must be in the same series for coupling body and the coupling insert to connect. All but the PLC series and PMC series are interchangeable no matter what size in the series the end connections are. On the PLC series and PMC series the flows have to match for them to connect.
A complete set is made up of the coupling body and the coupling 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 need to purchase both to have a complete coupling. Below is some general information on the quick disconnects that we offer:
