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.

Plastic Luer Lock Tube Couplings with Shut-Off for Air and Water
A built-in shut-off valve stops the flow when you separate these couplings, so air or water won’t leak from your line. Highly versatile, these couplings are compatible with any luer lock plug, socket, syringe, or needle. They secure with a half turn, so they’re often used in lines that are frequently disconnected. Thanks to their compact body, they fit in tight spaces. Use them in low-pressure applications.
Made of nylon, these couplings are lightweight and have good impact and abrasion resistance.
Note: For a complete coupling, order a plug and a socket.
- Temperature Range: -50° to 150° F
- Tubing: Use with firm or soft (Durometer 35A-85A) PVC plastic or silicone rubber
Barbed plugs and sockets insert into tubing and secure with a clamp.
