A built-in shut-off valve stops airflow when the fittings are disconnected from tubing.

Made of nickel-plated brass, these tube fittings resist corrosion better than plain brass fittings. The male threaded ends connect to NPT, NPTF, BSPP, BSPT, and other universal threads, so you don’t have to bother matching exact thread types.

Made of brass, these fittings have good corrosion resistance.

The threads on these fittings mate with NPT, NPTF, BSPT, and BSPP threads.

Ball bearings allow these fittings to rotate 360°, even after they are tightened. They have a special seal that reduces friction to allow for continuous rotation.
