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 Steel Threaded Pipe Nipples and Pipe

Also known as Schedule 40, this pipe is designed for low-pressure applications. Use in noncorrosive applications.

Welded pipe has a weld bead on the inside. Seamless pipe has a smooth interior for unrestricted flow and is stronger than welded pipe.

Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.
