How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

High-Pressure Brass Threaded Pipe Fittings

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

High-Pressure Plated Brass Threaded Pipe Fittings

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.

Miniature High-Pressure Brass Threaded Pipe Fittings

When space in your pipe line is limited, choose these miniature fittings that are one inch or less in length.

Tubing and Tube Fittings

Push-to-Connect Tube Fittings for Air

Push-to-Connect Tube Fittings with Shut-Off for Air

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

Brass Push-to-Connect Tube Fittings for Air

Made of brass, these fittings have good corrosion resistance.

Nickel-Plated Brass Push-to-Connect
Tube Fittings for Air

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

Moisture-Resistant Push-to-Connect
Tube Fittings for Air and Water

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

Low-Temperature/High-Pressure D.O.T.
Push-to-Connect Tube Fittings for Air

Use at pressures up to 250 psi.

Weld-Spatter-Resistant Push-to-Connect
Tube Fittings for Air and Water

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

High-Pressure 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.

High-Temperature Push-to-Connect
Tube Fittings for Air and Water

Withstanding temperatures up to 300° F, these fittings have the highest temperature rating of all our push-to-connect tube fittings for air and water.

Brass Low-Pressure Barbed
Tube Fittings for Air and Water

Fittings have good corrosion resistance.

Brass Quick-Disconnect Tube Couplings for Air

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

High-Pressure Quick-Disconnect Tube Couplings for Air

Couplings can handle pressures up to 250 psi.

Low-Profile High-Pressure
Quick-Disconnect Tube Couplings for Air

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

Brass Compression Tube Fittings for Air and Water

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.

Yor-Lok Fittings for Copper Tubing

Precision Compression Fittings for Copper Tubing

Also known as instrumentation fittings, these are made to tighter tolerances than standard compression fittings. They are compatible with Parker CPI fittings.
