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

Combo cap/plugs close off a plug on one end and a socket with the other. They save space by doing the job of both a cap and an end plug.
Stainless Steel Luer Lock Tube Couplings for Air and Water
Use these luer lock couplings to quickly connect low-pressure air and water lines. Made of stainless steel, they’re more durable than plastic couplings. Luer lock connections are universal, so you can connect any plug and socket to each other, regardless of the pipe or tube size. You can also connect them to syringes and needles. These couplings have a compact body, so they’ll fit in tight spaces. All are open-flow style, so there is no shut-off valve to stop the flow when the coupling is separated.
303 stainless steel couplings have very good corrosion resistance.
316 stainless steel couplings have excellent corrosion resistance.
Note: For a complete coupling, order a plug and a socket.

Brass Luer Lock Tube Couplings for Air
Quickly connect low-pressure air lines with these luer lock couplings. Made of brass, they are stronger and more durable than plastic tube couplings. These couplings have a nickel plating for extra protection against corrosive environments. Luer lock connections are universal, so you can connect any plug and socket to each other, regardless of the pipe or tube size. You can also connect them to syringes and needles. These couplings have a compact body, so they’re easy to fit in tight spaces. All are open-flow style, so there is no shut-off valve to stop the flow when the coupling is separated.
Note: For a complete coupling, order a plug and a socket.
Luer Lock Tube Couplings for Plastic and Rubber Tubing—Chemicals
- For Use With: Acetic Acid, Bleach, Ethanol, Hydrochloric Acid, Nitric Acid, Phosphoric Acid, Sulfuric Acid
- Tubing: Use with soft (Durometer 40A-65A) PVC plastic or silicone rubber
A staple in labs, these couplings are highly versatile, fitting any luer lock plug, socket, syringe, or needle. They lock together with a push and turn, so they work well in lines that are frequently disconnected. Use them in low-pressure applications. They have a compact body for installation in tight spaces. Made of PVDF, they resist most acids, alcohols, and organic solvents. PVDF is also known as Kynar.
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.
Nylon couplings have excellent impact and abrasion resistance. Use them in general purpose applications. Polyolefin couplings are BPA-free and autoclavable. Polypropylene couplings resist moisture and chemicals, including solvents. They also stand up to impact and abrasion.
Plugs with a locking ring are more secure than those without a locking ring. Give the ring a half turn to lock them in place. You can’t remove the locking ring.
