Made entirely of acetal, these couplings are lighter in weight than metal quick-disconnect couplings. They are moisture resistant, so they won’t absorb water and lose strength, even in high-humidity environments. A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them if you need frequent access to a line. All Plastic-shape plugs are compatible with any of the Plastic-shape sockets, regardless of the pipe size.

Plugs are also known as nipples.

Sockets have a shut-off valve that stops the flow when the coupling is separated, so air or water won’t leak from the line. They are push-to-connect style. To connect, push the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects.

Plugs and sockets with a barbed connection insert into plastic or rubber hose and secure with a crimp-on hose ferrule.

Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.
