Push-to-Connect Tube Fittings with Shut-Off for Air
- Temperature Range: 32° to 140° F
- Tubing: Fittings with Blue Release Ring: Use with firm or hard (Durometer 95A-95D) nylon plastic or polyurethane rubber
Fittings with Black Release Ring: Use with firm (Durometer 95A-45D) polyurethane rubber - Specifications Met: ISO 14743, except fittings with blue release ring
A built-in shut-off valve stops airflow when the fittings are disconnected from tubing. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting. Fittings have good corrosion resistance.
Identification rings (sold separately) snap over the release ring so you can color-code your lines.
Clips (sold separately) align and organize your tubing and fittings.

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—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.
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.

Precision Compression Fittings for Copper Tubing
- For Use With: Air, Cutting Oil, Ethyl Alcohol, Fuel Oil, Gasoline, Hydraulic Fluid, Isopropyl Alcohol, Mineral Oil, Natural Gas, Steam, Water
- Temperature Range: -40° to 350° F
- Tubing: Use with seamless copper that meets ASTM B68, ASTM B75, or ASTM B88
- Compatible With: Parker CPI
Made to tighter tolerances than other compression fittings, these are designed for high-precision applications. They are also known as instrumentation fittings and flareless fittings. They come with a nut and a single sleeve (ferrule). The sleeve bites into tubing as you tighten the nut to create a strong seal. Fittings are brass for good corrosion resistance.
Caps for tubing have a nut and a sleeve so you can close off the end of your tubing in place of a fitting.

Yor-Lok Fittings for Copper Tubing
- For Use With: Air, Cutting Oil, Diesel Fuel, Fuel Oil, Gasoline, Hydraulic Fluid, Mineral Oil, Water
- Temperature Range: -40° to 400° F
- Tubing: Use with seamless copper
- Specifications Met: ASME B31.3
A nut with two sleeves (ferrules) gives these fittings extra gripping power. The sleeves bite into tubing as you tighten the nut, creating a strong seal. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. Fittings are brass for good corrosion resistance. They are compatible with Swagelok®, Let-Lok, and A-Lok fittings.
