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.

Thick-Wall Plastic Pipe Fittings for Water

Connect these fittings to thick-wall plastic pipe—they have thicker, stronger walls than standard-wall fittings, so they can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. They can withstand pressures up to 900 psi.

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.

CPVC Pipe Fittings for Hot Water

Connect to CPVC pipe for use in high-temperature plumbing and water supply applications up to 200° F.

UV-Resistant Polypropylene Pipe Fittings for Chemicals

Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand acids, solvents, and other harsh substances.

High-Temperature PTFE Pipe Fittings for Chemicals

Extreme temperatures are no problem for these fittings—they’re made of PTFE, so they can withstand a wider temperature range than any of our other plastic pipe fittings for chemicals. They are commonly used in high-purity chemical flow processes, such as semiconductor and clean room applications.

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.

Tube Fittings for Plastic and Rubber Tubing

Push-to-Connect Tube Fittings for Air

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.

Plastic Quick-Disconnect Tube
Couplings for Air and Water

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

Plastic Compression Tube Fittings for Air

Lighter in weight than their metal counterparts, these compression fittings are polypropylene.

Plastic Compression Tube Fittings for Water

Made of acetal, these compression fittings are lighter in weight than metal compression fittings and won’t absorb moisture when used in wet environments.

Plastic Push-to-Connect Tube Fittings for Chemicals

Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push, and an internal gripping ring and fluoroelastomer O-ring hold the tubing tight.

Compression Fittings for Plastic Tubing—Chemicals

Fittings have a sleeve that bites into tubing as you tighten the nut to form a seal in applications up to 120 psi. Also known as flareless fittings.

Quick-Disconnect Couplings for Plastic
and Rubber Tubing—Chemicals

Quick-disconnect couplings consist of a plug and a socket that join with a latch so you can easily connect and disconnect your line. Use in applications up to 120 psi.

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.

Compression Tube Fittings for Food and Beverage

These plastic compression fittings meet NSF/ANSI Standard 51 for food contact.

Quick-Disconnect Tube
Couplings for Food and Beverage

These quick-disconnect couplings meet NSF/ANSI 169 for food equipment.
