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.

Sleeves for Precision Compression
Fittings for Stainless Steel Tubing

Sleeves for Compression Fittings
for Stainless Steel Tubing

Use these sleeves with compression nuts and fittings to create a strong seal on stainless steel tubing.

Sleeves for High-Pressure Compression
Fittings for Stainless Steel Tubing

When used with high-pressure compression fittings and nuts, these sleeves bite into stainless steel tubing to form a strong seal.

Sleeves for Compression Fittings for Copper Tubing

Nuts for Compression Fittings for Copper Tubing

Use these nuts with compression sleeves and fittings to create a strong seal on copper tubing.

Sleeves for Nickel-Plated Brass
Compression Fittings for Copper Tubing

Use these sleeves with compression nuts and fittings to create a strong seal on copper tubing.

Nuts for Nickel-Plated Brass
Compression Fittings for Copper Tubing

Create a strong seal on copper tubing when you couple these nuts with compression sleeves and fittings.

Sleeves for Vibration-Resistant
Compression Fittings for Copper Tubing

Sleeves for Compression Fittings for Steel Tubing

Use these sleeves with compression nuts and fittings, sometimes called bite fittings, to create a strong seal on steel tubing. They are also known as ferrules.

Sleeves for High-Pressure
Compression Fittings for Steel Tubing

Use these sleeves—also known as ferrules—with high-pressure compression nuts and fittings. They withstand about twice as much pressure as sleeves for standard compression fittings, so they’re good for hydraulic power applications.

Tube Fittings for Plastic and Rubber Tubing

Sleeves for Brass Compression
Tube Fittings for Air and Water

Use these sleeves with brass compression nuts and fittings to create a seal on plastic and rubber tubing.

Nuts with Built-In Sleeve for Quick-Assembly Brass
Compression Tube Fittings for Air and Water

Sleeves for Quick-Assembly Brass
Compression Tube Fittings for Air and Water

Use these to replace a damaged sleeve (ferrule) in quick-assembly compression nuts.

Sleeves for Tight-Seal Brass Compression
Tube Fittings for Air and Water

Sleeves for D.O.T. Brass
Compression Tube Fittings for Air

Nuts with Built-In Sleeve for Plastic
Compression Tube Fittings for Water

Use these nuts with plastic compression fittings to create a seal on plastic tubing. They're moisture-resistant acetal, so they won't absorb water and soften, even in high-humidity environments.

Nuts with Built-In Sleeve for Plastic
Compression Tube Fittings for Air

Use these nuts with plastic compression fittings to create a seal on plastic tubing. They have a built-in sleeve (ferrule), so the sleeve is positioned correctly for installation.

Nuts with Built-In Sleeve for High-Temperature
Compression Tube Fittings for Food and Beverage

Use these nuts with high-temperature compression fittings for food and beverage to create a seal on plastic tubing.
