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.

Acetal plugs and sockets are stronger and harder than polypropylene plugs and sockets, making them less likely to scratch. Their slippery surface also makes them more wear resistant. They resist moisture, so they won't crack or become brittle when used in humid environments.

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.

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