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.

Low-Pressure Iron and Steel Threaded Pipe Fittings

Use these fittings for low-pressure applications in noncorrosive environments.

Low-Pressure Galvanized Iron
and Steel Threaded Pipe Fittings

The galvanized finish on these fittings provides fair corrosion resistance. Fittings are for use in low-pressure applications.

Thick-Wall Butt-Weld Steel Unthreaded Pipe Fittings

With thicker, stronger walls than our standard-wall butt-weld pipe fittings, these fittings stand up to your high strength applications.

Standard-Wall Butt-Weld Steel
Unthreaded Pipe Fittings

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Low-Pressure Aluminum Threaded Pipe Fittings

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.

Drain, Waste, and Vent ABS
Pipe Fittings for Chemicals

These fittings are an economical option for chemical waste systems. Fittings are ABS plastic, which has excellent strength and impact resistance and good chemical resistance.

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.

Tubing and Tube Fittings

High-Polish Metal Quick-Clamp
Sanitary Tube Fittings

The smooth finish inside these stainless steel quick-clamp fittings makes it easy to remove product residue.

Socket-Connect Fittings for Stainless Steel Tubing

Use at pressures up to 1,500 psi.

Solder-Connect Fittings for Copper Tubing

Solder these fittings to tubing for a permanent, leak-tight connection. They are also known as sweat fittings.

Cleaned and Bagged Solder-Connect
Fittings for Copper Tubing

When cleanliness is crucial to your application, choose these fittings that are individually cleaned and bagged to prevent contamination.

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.

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.
