Push-to-Connect Tube Fittings for Air
UN/UNF (SAE Straight)
Male Threads with Gasket
- 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 PTFE thread sealant offer extra protection against leaks.
Metric male threads have either a gasket or a thread sealant to protect against leaks. BSPP and UN/UNF (SAE Straight) male threads have a gasket to protect against leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

High-Temperature Brass Push-to-Connect Tube Fittings for Air and Water
- Temperature Range: 0° to 300° F
- Tubing: Use with firm or hard (Durometer 95A-65D) nylon plastic or polyurethane rubber
- Specifications Met: ISO 14743
These fittings have the highest temperature rating of all our brass push-to-connect tube fittings for air and water. 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. They are nickel-plated for very good corrosion resistance.
Male BSPP threads have a fluoroelastomer O-ring to prevent leaks.
For technical drawings and 3-D models, click on a part number.
Fittings with intermittent swivel rotate 360° before and after installation as needed to allow movement in the system and to prevent kinking.
Fittings with external hex allow for easy adjustments in tight spaces; they are also known as banjo-style fittings.

Weld-Spatter-Resistant Push-to-Connect Tube Fittings for Air and Water
- Temperature Range: 32° to 100° F
- Tubing: Use with firm or hard (Durometer 90A-50D) nylon plastic or polyurethane rubber
Made of flame-resistant material, these fittings are good for welding and other applications where sparks occur. 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. They have good corrosion resistance.

Tight-Space 37° Flared Fittings for Aluminum Tubing
- For Use With: Air, Cutting Oil, Diesel Fuel, Fuel Oil, Gasoline, Hydraulic Fluid, Mineral Oil, Water
- Tubing: Use with seamless aluminum
Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on tubing that is flared to 37°. Fittings are aluminum, which is lightweight with good corrosion resistance. They require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.
