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 Galvanized Steel
Threaded Pipe Nipples and Pipe

Made of galvanized steel, this Schedule 40 pipe has fair corrosion resistance and is designed for low-pressure applications.

Standard-Wall Galvanized Steel Pipe Nipples
and Pipe for Joining Dissimilar Metals

A plastic sleeve prevents destructive corrosion when connecting different metals.

Standard-Wall Galvanized Steel Threaded
Pipe Nipples and Pipe with Sealant

The acrylic sealant on this pipe offers extra protection against leaks. Also known as schedule 40 pipe, this pipe is designed for use in low-pressure environments.

Standard-Wall Galvanized Steel Threaded
Pipe Nipple and Pipe Assortments

Assortments contain threaded pipe in various lengths.

Thick-Wall Galvanized Iron and Steel
Threaded Pipe Nipples and Pipe

Typically used with medium-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 80.

Compact Extreme-Pressure
Steel Threaded Pipe Fittings

These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

Compact Precision Extreme-Pressure
Steel Threaded Pipe Fittings

Made to tighter tolerances than other steel pipe fittings, these are also known as instrumentation fittings.

Extra-Thick-Wall Galvanized Steel
Threaded Pipe Nipples and Pipe

Typically used with high-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 160.

Vacuum Fittings for Steel Tubing

Use these fittings in an air vacuum system to avoid the hassle of brazing and welding. Insert two fittings into a clamp and tighten to form a secure seal in steel tubing.
