Plastic Quick-Disconnect Tube Couplings for Air and Water

Lighter in weight than their metal counterparts, these quick-disconnect couplings are plastic. They consist of a plug and a socket that allow you to frequently connect and disconnect your line.
Latch-lock sockets disconnect by pressing the latch.
Acetal plugs and sockets are moisture resistant, so they won’t absorb water and lose strength, even in high-humidity environments. Plug and Sockets with shut-off have a valve to stop the flow when the coupling is separated, so air or water won’t spill from your line.
Note: For a complete coupling, order a plug and a socket with the same coupling size.

Multiline Quick-Disconnect Tube Couplings for Air

Don’t get your lines crossed—use one of these couplings to quickly connect or disconnect multiple tubes at once. They keep tubes organized and optimize space in tight spots. Often used in robotics, these couplings are ideal for complex pneumatic systems.
Through-wall couplings allow you to connect and disconnect air lines on a panel or machine. This is useful when you are going to transport and reconnect your equipment on site.
Barbed-connect fittings are for soft tubing.
Keyed couplings prevent mixing and matching the wrong lines, since they’ll only connect with a plug or socket that is keyed the same.
For a complete coupling, order a plug and a socket with the same coupling size.
For technical drawings and 3-D models, click on a part number.




- Maximum Pressure: 100 psi @ 72° F
- Temperature Range: -40° to 180° F
- Tubing: Use with soft or firm (Durometer 45A-90A) polyurethane rubber or PVDF plastic
To connect the coupling, slide the latch to the lock position. To disconnect, slide the latch to the open position. Made of plastic, these couplings are lighter in weight than brass couplings.
To install in a panel, machinery, or bulkhead, add a through-wall adapter ring (sold separately).

Barbed Fittings: Use with soft or firm (Durometer 65A-80A) polyurethane rubber
Compression Fittings: Use with hard or firm (Durometer 80A-60D) nylon or polyethylene plastic - Specifications Met: NSF/ANSI 169
Couplings consist of a plug and a socket (sold separately) that join with a latch, so you can frequently connect and disconnect your line. To connect, insert the plug into the socket; to disconnect, press the latch on the socket and remove the plug. They’re made of FDA-approved materials, including moisture-resistant plastic that won’t absorb liquid and lose strength, even in high-humidity food and beverage applications.
Plugs and sockets with shut-off have a valve to stop the flow when the coupling is separated, so fluid won’t spill from your line.
Note: For a complete coupling, order a plug and a socket with the same coupling size.

Push-to-Connect Fittings for Food and Beverage

- Temperature Range: 35° to 140° F
- Tubing: See table
- Specifications Met: See table
Also known as instant fittings, these connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect fittings with a release ring, push on the release ring and pull the tubing out of the fitting.
Acetal fittings resist moisture, so they won’t soften and lose strength in humid environments. They meet NSF/ANSI 51 for safe use with food and NSF/ANSI 61 for safe use with drinking water.
Black fittings have excellent UV resistance and are suitable for outdoor environments.

Fittings with tube stem insert into the push-to-connect end of another fitting in place of a length of tubing.
