Nickel-Plated Brass Push-to-Connect Tube Fittings for Air

- For Use With: Air, Lubricated Air
- Temperature Range: 0° to 140° F
- Tubing: Fittings with Release Ring and Fittings with no Release Type: Use with firm or hard (Durometer 95A-60D) nylon plastic, polyethylene plastic or polyurethane rubber
Fittings with Release Sleeve: Use with firm or hard (Durometer 95A-60D) polyethylene plastic or polyurethane rubber
Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings. 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 or sleeve and pull the tubing out of the fitting.
Fittings with thread sealant offer extra protection against leaks.
Metric and UN/UNF (SAE Straight) male threads with gasket or thread sealant provide extra protection against leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

Push-to-Connect Tube Fittings for Air

- Temperature Range: 0° to 170° F, except polybutylene plastic fittings are 32° to 140° F
- Tubing: Use with firm (Durometer 95A-45D) polyethylene plastic or polyurethane rubber
- Specifications Met: ISO 14743, except cartridges and polybutylene plastic fittings
Insert tubing into these fittings and an internal gripping ring and O-ring hold the tubing tight. They are also known as instant fittings. To disconnect, push on the release ring and pull the tubing out of the fitting. Fittings have good corrosion resistance. Use them in low-pressure applications.
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.
For technical drawings and 3-D models, click on a part number.

Fittings with tube stem insert into the push-to-connect end of another fitting in place of a length of tubing.
