Aluminum Low-Pressure Barbed Tube Fittings for Air and Water
- For Use With: Air, Lubricated Air, Water
- Temperature Range: -40° to 230° F
- Tubing: Use with hard (Durometer 75A-60D) EVA plastic, polyethylene plastic, polyurethane rubber or PVDF plastic
Made of aluminum, these fittings are lighter in weight than other metal barbed tube fittings and have good corrosion resistance. The barb grips onto tubing, providing a secure hold with no clamp required.
Metric, BSPP, and UN/UNF (SAE Straight) male threads have a gasket or O-ring for a tight seal. 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.

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

Nickel-Plated Brass Push-to-Connect Tube Fittings for Air
- 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.
Fittings with thread sealant offer extra protection against leaks.
