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.

Temperature Range: -210° to 270° F
Tubing: Use with firm or soft (Durometer 45A-90A) polyurethane rubber or PVC plastic

Monitor flow with these clear fittings. They have a single barb that creates a smooth clamping surface for extra-tight connections that minimize leaks. Fittings are polycarbonate for excellent impact resistance.

Plastic Luer Lock Tube Couplings for Air and Water

For Use With: Nylon Plastic: Air, Water
Polycarbonate Plastic: Air
Polypropylene Plastic: Water
Temperature Range: See table
Tubing: Use with soft (Durometer 40A-65A) PVC plastic or silicone rubber

Made of plastic, these couplings are lighter in weight than metal luer lock couplings. They're a popular choice in labs because of their versatility—they fit any other luer lock plug, socket, syringe, or needle. Quick to attach and detach, they’re often used in lines that are frequently disconnected. They have a compact body for easy installation in tight spaces. Use them in low-pressure applications. These couplings are open-flow style, so there is no shut-off valve to stop the flow when they’re separated.

Plugs with a locking ring are more secure than those without a locking ring. Give the ring a half turn to lock these couplings in place. You can’t remove the locking ring.

Note: For a complete coupling, order a plug and a socket.

Luer Lock Tube Couplings for Plastic and Rubber Tubing—High-Purity

For Use With: Air, Water
Temperature Range: Nylon Plastic: -50° to 275° F
Polyolefin Plastic: Up to 355° F
Polypropylene Plastic: -5° to 150° F
Tubing: Use with soft or firm (Durometer 50A-95A) polyolefin plastic, PVC plastic, silicone rubber, TPE plastic, or TPU plastic

To prevent contamination, these couplings are cleaned, double bagged, and packaged in a clean room. This makes them a great choice for applications where cleanliness is critical, such as semiconductor manufacturing. Known for their versatility, they fit any luer lock plug, socket, syringe, or needle. They’re quick to attach and detach, 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.

Note: For a complete coupling, order a plug and a socket.

Barbed couplings securely grip tubing and hose. Polyolefin couplings are BPA-free and autoclavable.

Plugs without a locking ring are quicker to install and remove than those with a locking ring. Also known as luer slip plugs, all they need is a light push to secure. Add a snap-on ring (sold separately) to lock the coupling in place and color code your line.
