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 brass, these fittings have good corrosion resistance.

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

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 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.

Don’t get your lines crossed—use one of these couplings to quickly connect or disconnect multiple tubes at once.

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

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

Lighter in weight than their metal counterparts, these quick-disconnect couplings are made of acetal plastic. They are moisture resistant, so they won’t absorb water and lose strength, even in high-humidity environments.

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.

Minimize leaks in your line—these fittings have a single barb that creates a smooth clamping surface for extra-tight connections.

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

Fittings can withstand temperatures up to 200° F.

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.

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

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

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

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.

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.

A PTFE seal on the tube end of these fittings allows for an extra-strong connection in high-vibration applications.

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

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.

For applications that require an extra level of cleanliness, these fittings are individually bagged to prevent contamination.

These brass fittings have the strength to handle high-pressure applications.

The plating on these brass fittings creates a shiny finish and provides extra protection in corrosive environments. Fittings have the strength to handle high-pressure applications.

Use these fittings in extreme-pressure conditions up to 15,000 psi.

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.
