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.

Extra-Thick-Wall Steel Threaded Pipe Nipples and Pipe

Extra-thick walls give this pipe excellent strength to handle high-pressure applications. It is also known as Schedule 160. Pipe is seamless, so it has a smooth interior for unrestricted flow. It is for use in noncorrosive environments.

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

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

Also known as Schedule 160, this pipe has extra-thick walls for excellent strength. It has a galvanized finish that provides better corrosion resistance than our plain steel pipe. Pipe is seamless, so it has a smooth interior for unrestricted flow.

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