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 nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

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 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.

Color-code your lines by snapping these rings over the release ring on low-temperature D.O.T. 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.

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.

Use these luer lock couplings to quickly connect low-pressure air and water lines. Made of stainless steel, they’re more durable than plastic couplings.

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.

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

With no latch, these couplings have a compact design to fit in small spaces. They can handle pressures up to 700 psi.

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.

Fittings are 316 stainless steel, which has excellent chemical resistance and is more durable than plastic.

Quick-disconnect couplings consist of a plug and a socket that join with a latch so you can easily connect and disconnect your line.

Create corrosion-resistant connections in food and beverage lines with just a push. Also known as instant fittings, these fittings have an internal gripping ring and an O-ring that hold tight to tubing.

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.

These quick-disconnect couplings mate with a sanitary stainless steel quick-clamp fitting for use in dairy lines.

Tube supports slip inside tubing to prevent the walls from collapsing.

Create a push-to-connect junction in equipment with these fittings. To install, drill a stepped hole in your surface, push the fitting components into place, then insert your tubing.

Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 140 psi.

Connect quick-clamp sanitary tube fittings—also known as aseptic fittings—for a fast and easy way to access your line.

Connect extra-support quick-clamp fittings for a fast and easy way to access your line.

Also known as KF, QF, and NW fittings, these fittings are for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases.

Use these rings with quick-clamp high-vacuum fittings.

An alternative to bolt-together fittings, these fittings handle larger tube OD sizes than quick-clamp fittings. Also known as ISO-K high-vacuum fittings, the clamps have claws that grab hold of fittings with flanged ends.

Connect stainless steel tubing on one end and plastic tubing on the other end.

Create airtight seals in high-vacuum systems by placing these rings between two claw-clamp (ISO-K) or bolt-together (ISO-F) fittings.

Quickly connect low-pressure stainless steel lines with these couplings. Made of 316 stainless steel, they have excellent corrosion resistance.

Transfer liquids and gases into high-vacuum chambers with these assembled fittings, also known as feedthroughs. Their quick-clamp (ISO-KF) connections are easier to install and remove than bolt-on flanges.

Made of plastic, these fittings are lightweight compared to our brass push-to-connect fittings.

For use in high-vacuum systems, these fittings use a metal reinforced O-ring to create an airtight seal. Also known as KF, QF, and NW fittings, they’re used for high-vacuum applications such as vacuum coating and heat treating, leak testing, and analyzing gases.
