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.
Fittings with PTFE thread sealant offer extra protection against leaks.

Brass Quick-Turn Tube Couplings for Air
An all-brass body gives these couplings better strength and durability than plastic quick-turn couplings. They have a nickel plating for extra protection against corrosive environments. Also known as luer lock couplings, they consist of a plug and socket (sold separately) that connect with a half turn. They have a compact body, so they’re easy to fit in tight spaces. Plugs and sockets are open-flow style, so there is no shut-off valve to stop the flow when the coupling is separated. They have a universal connection, so the plugs will connect to any of the sockets, regardless of the pipe or tube size.
Note: For a complete coupling, order a plug and a socket.

Brass Push-to-Connect Fittings for Copper Tubing
- Temperature Range: 32° to 200° F
- Tubing: Use with K, M, L copper, polyethylene plastic
Connect these fittings to copper tubing with a push—no heat, solder, or flux required. They have an internal gripping ring and O-ring that hold the fitting secure. They also come with a tube support if you want to use them with polyethylene plastic (PEX) tubing. They are also known as instant fittings. Fittings are brass for good corrosion resistance. They are compatible with SharkBite® fittings. To adhere to safety standards for drinking water systems, use fittings that meet NSF/ANSI 61.
