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.
Nylon couplings have excellent impact and abrasion resistance. They’re for general purpose applications. Polypropylene couplings won’t absorb water and lose strength, even in high-humidity environments. They also stand up to chemicals, including solvents.
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.
Barbed plugs and sockets insert into tubing and secure with a clamp.

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. Polyolefin couplings are BPA-free and autoclavable.
