A spring-free flow path allows more air or water to pass through these tube couplings at lower line pressures than other quick-disconnect couplings. This reduces turbulence, foaming, bubbles, and blockage. They have a shut-off valve that stops the flow when the coupling is disconnected, so air or water won’t leak from your line. Unlike couplings with a button release, these have a safety slide to reduce accidental separation from bumps or drops. They’re often used in laboratories, pharmaceutical facilities, and other sterile environments. All are FDA compliant for direct contact with food.

When you insert the plug into the socket, it’ll connect with a click. To disconnect, slide the latch on the socket and remove the plug.

Polypropylene plugs and sockets are flexible yet tough, so they keep their shape and strength after repeated use. They are more water resistant than acetal plugs and sockets and can be completely submerged.

End plugs fit in the end of a socket to keep out dirt and debris.

Note: For a complete coupling, order a plug and a socket with the same coupling size.

Made of plastic, these couplings are lighter in weight than metal quick-turn couplings. Also known as luer lock couplings, they consist of a plug and socket (sold separately) that connect with a half turn. They have a compact body for easy installation in tight spaces. Plugs and sockets are open-flow style, so there is no shut-off valve to stop the flow when the coupling is separated. They have a universal connection, so the plugs will connect to any of the sockets, regardless of the pipe or tube size.

Polypropylene plugs and sockets are moisture resistant and won’t absorb water and lose strength, even in high-humidity environments.

Note: For a complete coupling, order a plug and a socket.
