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.

Brass Push-to-Connect Fittings for Copper Tubing

Choose these metal fittings when you need better durability than our plastic push-to-connect fittings.

Push-to-Connect Tube Fittings for Air

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.

Nickel-Plated Brass Push-to-Connect
Tube Fittings for Air

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

Weld-Spatter-Resistant Push-to-Connect
Tube Fittings for Air and Water

Designed for use in welding applications, these fittings are flame retardant.

Low-Temperature D.O.T.
Push-to-Connect Tube Fittings for Air

Connect air brake lines with fittings that won’t crack in sub-zero temperatures. They meet Department of Transportation FMVSS 571 safety standards, so they’re often used in commercial trucks and trailers.

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.

Plastic Quick-Disconnect Tube
Couplings for Air and Water

Lighter in weight than metal quick-disconnect couplings, these couplings are plastic.

Multiline Quick-Disconnect Tube Couplings for Air

Don’t get your lines crossed—use one of these couplings to quickly connect or disconnect multiple tubes at once.

Push-to-Connect Tube
Fittings for Hot Drinking Water

Fittings can withstand temperatures up to 200° F.

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.

Plastic Push-to-Connect Tube Fittings for Chemicals

Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push. An internal gripping ring holds the tubing tight.

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.

Push-to-Connect Fittings for
Plastic Tubing—High-Purity

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 140 psi.

Build-Your-Own Air Hose System

With an easy-to-cut hose and push-to-connect fittings, you can install a compressed air line system in just a few hours.

Touch-Safe Insulated Cryogenic
Hose with Tube Stem Fittings

Sealed vacuum insulation and a reflective barrier inside this hose maintains the temperature of liquids as cold as -325° F. Similar to a thermos, this prevents heat transfer, so the exterior of the hose won’t freeze or form condensation. The tube stems on each end slide into tube fittings on a freezer or other equipment in your plant or laboratory.

Hose with Fittings for Plumbing Fixtures

Hook up faucets and other appliances to a water supply with these flexible hoses.
