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.

Push-to-Connect Tube Fittings for Air

Aluminum Low-Pressure Barbed
Tube Fittings for Air and Water

Aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

Nickel-Plated Brass Low-Pressure
Barbed Tube Fittings for Air and Water

The nickel plating on these fittings provides better corrosion resistance than unplated brass fittings.

Choose-a-Color Aluminum Low-Pressure
Barbed Tube Fittings for Air and Water

Color-code fittings for easy identification. These aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

Stainless Steel High-Pressure Barbed
Tube Fittings for Air and Water

Made of stainless steel, these fittings have better corrosion resistance than brass fittings.

Screw-On Nut Barbed Tube Fittings for Air

You don't need a clamp to secure these fittings to tubing. They have a nut on the barbed end that tightens to hold the tubing in place.

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.

High-Flow Quick-Disconnect
Tube Couplings for Air and Water

A spring-free flow path allows more air or water to pass through these tube couplings at lower line pressures than other quick-disconnect couplings.

Multipurpose Build-Your-Own Quick-Disconnect
Tube Couplings for Air and Water

Create custom couplings to save space and snake around obstructions. These couplings let you swap in different ends to change the connection size, type, and orientation to fit your specific setup.

High-Temperature Plastic Barbed
Tube Fittings for Food and Beverage

Fittings withstand temperatures up to 220° F.

Super-Flow Plastic Barbed Tube
Fittings for Food and Beverage

A smooth interior reduces friction and prevents product buildup, ensuring an unrestricted flow.

Push-to-Connect Fittings for Food and Beverage

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.

High-Flow Quick-Disconnect
Tube Couplings for Chemicals

A spring-free flow path allows more chemicals to pass through these tube couplings at lower line pressures than other quick-disconnect couplings.

Push-to-Connect Tube Fittings for Drinking Water

These fittings keep their strength in moist environments and meet NSF/ANSI 61 for drinking water. Also known as instant fittings.

Push-to-Connect Tube
Fittings for Hot Drinking Water

Fittings can withstand temperatures up to 200° F.

Barbed Tube Fittings for Drinking Water

Connect these fittings to tubing with a ring and a crimping tool (both sold separately). Safe to use with drinking water, these fittings meet the strict standards of NSF/ANSI 61.

Crimping Tools for Barbed
Tube Fittings for Drinking Water

Use these tools with a crimping ring (sold separately) to connect barbed tube fittings for drinking water to tubing.

Barbed Fittings for Plastic and
Rubber Tubing—High-Purity

Fittings have a barb that grips onto tubing. Use in applications up to 150 psi.

Push-to-Connect Fittings for Stainless Steel-to-Plastic Tubing

Push-to-Connect Fittings for
Stainless Steel-to-Plastic Tubing

Connect stainless steel tubing on one end and plastic tubing on the other end.

High-Pressure Barbed Plastic Pipe Fittings for Water

High-Pressure Barbed Plastic
Pipe Fittings for Water

Use for pressures up to 200 psi. Also known as insert fittings, these slide into semi-flexible plastic pipe and secure with a clamp.

Flow-Control Valves

Check Valves with Barbed Fittings for Vacuum

Barbs grip onto tubing, providing a secure hold.

On/Off Valves with Barbed Fittings for Chemicals

Barbs grip onto tubing, providing a secure hold. To withstand aggressive and corrosive solutions in chemical-processing applications, these valves have a plastic body and a chemical-resistant seal.
