Moisture-Resistant Push-to-Connect Tube Fittings for Air and Water
- For Use With: Air, Lubricated Air, Water,
except Manifolds with Swivel: Air, Water - Temperature Range: 32° to 100° F
- Tubing: Use with firm (Durometer 90A-95A) nylon plastic or polyurethane rubber
These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications. 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.
Nickel-plated brass fittings have better corrosion resistance than unfinished brass fittings.
Fittings with thread sealant offer extra protection against leaks.

Fittings with intermittent swivel rotate 360° before and after installation as needed to allow movement in the system and to prevent kinking.

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.
