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.

These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications.

Connect air brake lines with fittings that won’t crack in sub-zero temperatures. They meet Department of Transportation FMVSS 571 safety standards, so they’re often used in commercial trucks and trailers.

Withstanding up to 300° F, these fittings have the highest temperature rating of all our brass push-to-connect tube fittings for air and water.

An all-metal body and built-in tube support or dual seals allow these fittings to handle the highest pressure ratings of all our push-to-connect tube fittings.

Made of brass, these couplings are more durable than plastic couplings.

Don’t get your lines crossed—use one of these couplings to quickly connect or disconnect multiple tubes at once.

Create custom couplings to save space and snake around obstructions. These couplings let you swap in different ends to change the connection size, type, and orientation to fit your specific setup.

Also known as instant fittings, these connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 150 psi.

Connect hot food and beverage lines with just a push. Also known as instant fittings, they have an internal gripping ring and an O-ring that hold tight to tubing.

Add a push-to-connect junction to unthreaded ports for easy connections with tubing. To install, drill a stepped hole in your surface, push the fitting components into place, and insert your tubing.
