Universal-Thread Moisture-Resistant
Push-to-Connect Tube Fittings for Air and Water


Threads
with Gasket
- Temperature Range: 32° to 100° F
- Tubing: Use with firm (Durometer 90A-95A) nylon plastic or polyurethane rubber
The threads on these fittings mate with NPT, NPTF (Dryseal), BSPT, and BSPP threads. The male threads have a gasket to protect against leaks. Fittings are moisture and corrosion resistant, so they’re good for water and humid 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.
Static dissipative fittings divert static electricity.
