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.

Thick-Wall Plastic Pipe Fittings for Water

Connect these fittings to Schedule 80 pipe. With thicker, stronger walls than standard-wall fittings, they can handle heavy duty supply applications, such as water processing, wastewater treatment, and irrigation.

CPVC Pipe Fittings for Hot Water

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

Aboveground Standard-Wall PVC Pipe
Fittings for Drain, Waste, and Vent

These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.

Underground PVC Pipe Fittings
for Drain, Waste, and Vent

With thinner walls than Schedule 40 fittings, these are lighter in weight and have more space on the inside for high-flow applications, such as underground gravity-flow sewer and storm drainage lines. They are also known as SDR 35 fittings.

Gravity-Flow CPVC Pipe Fittings
for Corrosive Chemical Waste

These fittings are NSF certified for use in corrosive waste gravity-flow systems. Made of CPVC, they have better chemical resistance than ABS plastic gravity-flow fittings and can stand up to highly-corrosive acids and other harsh substances.

Low-Pressure Clamp-On Connectors
for Drain, Waste, and Vent

To make installing and maintaining systems easy, these connectors come with clamps that form a strong seal on pipe and fittings once tightened.

Tube Fittings for Plastic and Rubber Tubing

Socket-Connect Fittings for
Plastic Tubing—Air and Water

Slide tubing into these fittings and secure with a clamp. Use at low pressures up to 80 psi.

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.

Easy-View Plastic Barbed
Tube Fittings for Air and Water

Monitor flow with these clear fittings.

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

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

Barbed Fittings for Plastic and
Rubber Tubing—Chemicals

Fittings have a barb that grips onto tubing. Use in applications up to 120 psi.

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.

Stainless Steel Barbed Tube
Fittings for Food and Beverage

Made of stainless steel, these fittings are more durable than plastic barbed tube fittings for food and beverage.

Barbed Fittings for Plastic and
Rubber Tubing—Gasoline

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

Barbed Fittings for Plastic and
Rubber Tubing—High-Purity

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