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.

Industrial Quick-Disconnect Hose Couplings for Air
A complete coupling consists of a plug and a socket (both sold separately or in a set) that connect and disconnect quickly. Use them if you need frequent access to a line. They are also known as industrial interchange couplings. All Industrial plugs are compatible with any of the Industrial sockets of the same coupling size, regardless of the pipe size or barbed hose ID.
Steel is stronger and more durable than other metals. Zinc-plated steel has fair corrosion resistance and should be used primarily in dry environments. Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.

- Maximum Pressure: 230 psi @ 72° F
- Temperature Range: 0° to 212° F
Sockets have a shut-off valve that stops the flow when the coupling is separated, so air won’t leak from the line.
Manifolds distribute air to multiple lines.
Push-to-connect sockets join by forcefully pushing the plug and socket together until you hear a click. Unlike sleeve-lock sockets, you should not slide back the sleeve to connect. To disconnect, slide the sleeve on the socket forward until the plug ejects.

Stainless Steel Barbed Tube Fittings for Food and Beverage
- Temperature Range: -20° to 750° F
- Tubing: Use with soft or firm (Durometer 65A-90A) polyurethane rubber or PVC plastic
- Specifications Met: See table
Made of stainless steel, these fittings are more durable than plastic barbed tube fittings for food and beverage. They have single or multiple barbs that grip onto tubing.
