Universal-Thread Push-to-Connect Tube Fittings for Air and Water
Threads
with Gasket
- Temperature Range: 0° to 175° F
- Tubing: Use with firm (Durometer 85A-100A) nylon plastic or polyurethane rubber
- Specifications Met: ISO 14743
Make lightweight connections without the hassle of matching the exact thread type—these fittings connect to NPT, NPTF, BSPP, BSPT, and other universal threads. With a nylon body and nickel-plated brass threads, these fittings are lighter than most metal fittings, and withstand corrosion better than plain brass threads. They also have a reusable gasket to guard against leaks. Connect the tube ends to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect them, push the release ring and pull the tubing out of the fitting. These fittings are sometimes known as instant fittings. All meet ISO 14743, which is an international standard for push-to-connect fittings for plastic tubing.

Nickel-Plated Brass Push-to-Connect Tube Fittings for Air
(SAE Straight) 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 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.
NPTF (Dryseal) threads are compatible with NPT threads.

Drill-and-Install Push-to-Connect Tube Fittings for Air and Water
- Temperature Range: 35° to 150° F
- Tubing: Use with firm or hard nylon plastic or polyethylene plastic
Create a push-to-connect junction in equipment with these fittings. They have a release ring, a grasping ring for securing the tubing, and an O-ring. To install, create a stepped hole in your surface using tools like a CNC machine or lathe. Push the fitting components into place, then insert your tubing until the tube end is flush against the tube stop. To disconnect, push on the release ring and pull the tubing out of the fitting. They are made of moisture-resistant acetal, so they won’t soften and lose strength in high-humidity environments.
