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

A 316 stainless steel body gives these fittings the best corrosion resistance of all our metal push-to-connect tube fittings.

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

Connect high-pressure brake lines with fittings that won’t crack in frigid temperatures. Often used on commercial trucks and trailers, these fittings meet Department of Transportation FMVSS 571 safety standards.

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.

Made of brass, these fittings resist corrosion from water and are more durable than plastic and aluminum fittings.

You don't need a clamp to secure these fittings to tubing. They have a nut on the barbed end that tightens to hold the tubing in place.

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.

Safe for use in your air brake line, these fittings meet Department of Transportation FMVSS 571 standards. They’ve been tested for thermal cycling, vibration, and burst pressure, so put them to work right away.

Made of acetal, these compression fittings are lighter in weight than metal compression fittings and won’t absorb moisture when used in wet environments.

A built-in shut-off valve stops the flow when you separate these couplings, so air or water won’t leak from your line. Made of nylon, these couplings are lightweight and have good impact and abrasion resistance.

Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push. An internal gripping ring holds the tubing tight.

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.

These plastic compression fittings meet NSF/ANSI Standard 51 for food contact.

Fittings can withstand temperatures up to 200° F.
