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.

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

Prevent mixing the wrong high-pressure lines—these couplings are designed to only connect with a plug or socket of the same color.

A single sleeve (ferrule) compresses the tubing as you tighten the nut on these fittings, creating a strong seal. They are brass for good corrosion resistance.

Lighter in weight than their metal counterparts, these compression fittings are polypropylene.

Made of plastic, these couplings are lighter in weight than metal luer lock couplings. They're a popular choice in labs because of their versatility—they fit any other luer lock plug, socket, syringe, or needle.

Fittings have a sleeve that bites into tubing as you tighten the nut to form a seal in applications up to 120 psi. Also known as flareless fittings.

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

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

These fittings keep their strength in moist environments and meet NSF/ANSI 61 for drinking water. Also known as instant fittings.

Quick-disconnect couplings consist of a plug and a socket that join with a latch so you can easily connect and disconnect your line. Use in applications up to 150 psi.
