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.

Yor-Lok Fittings for Stainless Steel Tubing

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.

Front and Back Sleeves for Yor-Lok
Fittings for Stainless Steel Tubing

Nuts for Yor-Lok Fittings for Stainless Steel Tubing

Quick-Clamp High-Vacuum
Fittings for Stainless Steel Tubing

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.

Compression Fittings for Stainless Steel Tubing

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

Vibration-Resistant Ultra-High-Polish
Gasket Fittings for Stainless Steel Tubing

Fittings have two anti-torque rings that compress the gasket to prevent rotation and reduce particle generation in high-vibration applications.

Ultra-High-Polish Gasket Fittings
for Stainless Steel Tubing

Polished to a 15 Ra and under finish, these fittings have a mirror smooth interior. They are also known as ultra-high-purity fittings.

Compression Fittings for Steel Tubing

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

Vibration-Resistant Compression
Fittings for Steel Tubing

O-Ring Face Seal Fittings for Steel Tubing

A tube adapter sits flush against the flat face of the fitting so you can slide the steel tubing and fitting sideways to disconnect in cramped spaces. Also known as zero-clearance fittings.

Vibration-Resistant Compression
Fittings for Copper Tubing

The sleeve in these fittings is rubber instead of metal, so it cushions the tubing and absorbs vibration while creating a tight seal.

High-Pressure Quick-Disconnect Tube Couplings for Air

Couplings can handle pressures up to 250 psi.

Pipe and Pipe Fittings

Thick-Wall Plastic Pipe Fittings for Water

Connect these fittings to thick-wall plastic pipe—they have thicker, stronger walls than standard-wall fittings, so they can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. They can withstand pressures up to 900 psi.

Low-Pressure Clamp-On Connectors for Air

These connectors are for use in low-pressure air and vacuum conveying systems, as well as in gravity-flow systems.
