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

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

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

Designed for use in welding applications, these fittings are flame retardant.

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.

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

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 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.

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.

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

Fittings can withstand temperatures up to 200° F.

Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

The threads on the tube end of these fittings are Class 3A or 3B and adhere to tighter tolerances than other 37° flared fittings.

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included.

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on stainless steel tubing that is flared to 37°.

Bolt these fittings onto your ultra-high-vacuum chamber to transfer liquids and gases inside. Also known as feedthroughs, they come assembled with a flanged (CF) fitting, metal tubing, and two Yor-Lok tube fittings.

These fittings have two sleeves for extra gripping power. They bite into steel tubing as you tighten the nut to form a strong seal.
