Nickel-Plated Brass Push-to-Connect Tube Fittings for Air
UN/UNF (SAE) Male
Threads with Gasket
- For Use With: Air, Lubricated Air
- Temperature Range: 0° to 140° F, except plugs and straight connectors are 32° 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 release sleeve are easier to disconnect than fittings with a release ring because they are seamless and won't collect dirt and debris.
Metric and UN/UNF (SAE) male threads with gasket or thread sealant provide extra protection against leaks. UN/UNF (SAE) threads are also known as O-ring boss threads.

UN/UNF (SAE) Male
Threads with Gasket
Fittings with intermittent swivel rotate 360° before and after installation as needed to allow movement in the system and to prevent kinking.

Push-to-Connect Tube Fittings for Air
UN/UNF (SAE) Male
Threads with Gasket
- Temperature Range: 0° to 170° F
- Tubing: Use with firm (Durometer 95A-45D) polyethylene plastic or polyurethane rubber
- Specifications Met: ISO 14743, except 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.
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.
Metric male threads have either a gasket or a thread sealant to protect against leaks.
