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.

High-Pressure Iron and Steel
Threaded Pipe and Pipe Fittings

High-Pressure Galvanized Steel
Threaded Pipe and Pipe Fittings

A galvanized finish provides better corrosion resistance than other types of steel.

Medium-Pressure Iron and Steel
Threaded Pipe and Pipe Fittings

Use in medium-pressure applications up to 1,400 psi.

Extreme-Pressure Steel
Threaded Pipe and Pipe Fittings

Use in extreme-pressure applications up to 10,000 psi.

Low-Pressure Iron and Steel
Threaded Pipe and Pipe Fittings

Use in low-pressure applications up to 285 psi.

Iron and Steel Unthreaded
Pipe and Pipe Fittings

Pipe and fittings weld together for a permanent connection that is stronger and less likely to leak than threaded and clamp-on connections.

Iron and Steel Clamp-On
Pipe and Pipe Fittings

Pipe and fittings connect with a clamp, so they can be taken apart as needed for maintenance and repair.
