How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Quick-Disconnect Plastic-Shape Hose Couplings for Food and Beverage
Couplings are suitable for food and beverage applications and won’t impart tastes or odors to the product. 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 of the quick-disconnect food and beverage plugs are compatible with any of the quick-disconnect food and beverage sockets of the same coupling size, regardless of the pipe size. They are PVDF, which has excellent abrasion and corrosion resistance and withstands the damaging effects of UV light.
Plugs are also known as nipples.
Sockets have a shut-off valve that stops the flow when the coupling is separated, so product 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 back until the plug ejects.

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.
- 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).

Connect the coupling with a push and disconnect by pressing the latch. Made of plastic, these couplings are lighter in weight than brass couplings.
If you want the coupling to rotate freely after it’s installed to avoid kinks in your tube, choose one with a swivel.

A spring-free flow path allows more chemicals 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 chemicals 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 are often used in laboratories, pharmaceutical facilities, and other sterile environments.
Made of PVDF, also known as Kynar, these couplings have excellent chemical and UV resistance at ambient and elevated temperatures. They also resist abrasion, impact, flames, and corrosion. Compared to other quick-disconnect couplings for chemicals, these couplings can withstand higher temperatures—all the way up to 250° F.
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.
Note: For a complete coupling, order a plug and a socket with the same coupling size.
They have a single barb that grips onto tubing or hose and provides a smooth clamping surface for extra-tight connections that minimize leaks.
