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.

More

Pipe, Tubing, Hose, and Fittings

Tube Fittings for Plastic
and Rubber Tubing

Connect to tubing or pipe, typically in low-pressure applications.

Tube Fittings for
Stainless Steel Tubing

Fittings have very good to excellent corrosion resistance.

Compression Fittings for Steel Tubing

testString

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

Vibration-Resistant Compression
Fittings for Steel Tubing

testString

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

High-Pressure Compression
Fittings for Steel Tubing

testString

Thicker walls make these fittings—sometimes called flareless or bite fittings—withstand about twice as much pressure as standard compression fittings, so they’re good for hydraulic power applications.

Yor-Lok Fittings for Steel Tubing

testString

These fittings have two sleeves for extra gripping power. They bite into tubing as you tighten the nut to form a strong seal. Fittings can handle pressures up to 6,800 psi. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

Tube Fittings for Copper
and Brass Tubing

Hose Fittings

testString

Connect these fittings to lengths of hose. Hose fittings are typically used in high-flow, suction, and hydraulic applications.

Plastic Pipe and Pipe Fittings

testString

Plastic pipe and pipe fittings are lighter in weight than metal pipe and pipe fittings. They are typically for low- to medium-pressure applications up to 1,000 psi.

Manifolds

Manifolds

Also known as headers, manifolds allow you to distribute air or fluid to multiple locations from a single supply source.
