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.

Standard-Wall Plastic Pipe Fittings for Water

Connect these fittings to Schedule 40 plastic pipe—they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.

Plastic Pipe Fittings for Gasoline

Use these plastic fittings to connect gasoline fuel lines to machines and equipment. They have excellent corrosion resistance as well as high strength and impact resistance.

Plastic Pipe Fittings for Oil

Made of corrosion-resistant plastic, these fittings won’t deteriorate when used in oil applications. They have high strength and impact resistance.

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

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

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.

Plastic Barbed Tube Fittings for Air and Water

Barbs grip onto tubing.

Tight-Seal Plastic Barbed
Tube Fittings for Air and Water

Minimize leaks in your line—these fittings have a single barb that creates a smooth clamping surface for extra-tight connections.

Push-to-Connect Tube Fittings for Air

Brass Push-to-Connect Tube Fittings for Air

Made of brass, these fittings have good corrosion resistance.

Stainless Steel Push-to-Connect
Tube Fittings for Air and Water

A 316 stainless steel body gives these fittings the best corrosion resistance of all our metal push-to-connect tube 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.

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.

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.

Push-to-Connect Fittings for Plastic
Tubing—Food and Beverage

Also known as instant fittings, they 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.

Barbed Hose Fittings for Coolant

Designed for coolant applications up to 200 psi, these fittings have a standard barbed end that slides into hose and secures with a clamp.

Reducers for Flexible Plastic Conduit

Connect different sizes of conduit.
