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 and Pipe Fittings

Low-Pressure Cast Iron Threaded Pipe Fittings

Made of cast iron, these fittings are brittle and can be quickly opened with the strike of a sledge hammer in case of an emergency.

Low-Pressure Galvanized Iron and
Steel Threaded Pipe and Pipe Fittings

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

High-Pressure Iron and Steel
Threaded Pipe and Pipe Fittings

Use in high-pressure applications up to 6,000 psi.

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.

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.

Iron and Steel Pipe Fittings with Flanged Ends

Bolt the flanged end of these fittings to another same-size flange, pump, or valve with a gasket to create an access point in a pipe line.
