When cleanliness is crucial to your application, choose these fittings that are individually cleaned and bagged to prevent contamination.

With a nickel-plated finish, these compression fittings resist corrosion better than plain brass fittings.

These fittings include a nut with a built-in sleeve, so there’s no need to remove the nut for assembly.

Crimp these fittings to copper tubing with a crimping tool for a leak-tight connection that doesn’t require heat or soldering. They are comparable to Viega ProPress fittings.

The flared end of the fitting nests inside the fitting body, providing extra support to the tubing. Fittings are also known as inverted 45° flared fittings.

A nut with two sleeves (ferrules) gives these fittings extra gripping power. The sleeves bite into tubing as you tighten the nut, creating a strong seal.

Use these fittings to make leak-resistant connections without threading or soldering. Slide them over tubing and turn the end nuts to compress the gasket.

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

Made of brass, these fittings have good corrosion resistance.

Make lightweight connections without the hassle of matching the exact thread type—these fittings connect to NPT, NPTF, BSPP, BSPT, and other universal threads.

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

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.

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.

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.

The nickel plating on these fittings provides better corrosion resistance than unplated brass 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.

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.

These fittings include a nut with a built-in sleeve (ferrule), so there’s no need to remove the nut for assembly.

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.

Made of brass, these fittings withstand frequent washdowns in food-processing applications. They also adhere to NSF/ANSI safety standards, so they’re safe to use with food, beverages, and dairy.

These quick-disconnect couplings meet NSF/ANSI 169 for food equipment.

Connect drinking water lines with ease—these one-piece fittings have a built-in sleeve that crimps onto tubing for a leak-tight connection that doesn’t require heat or soldering. These fittings meet NSF/ANSI 61 for drinking water systems and are compatible with Viega PEX tubing.
