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.
