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 Stainless Steel Threaded Pipe Nipples and Pipe

Designed for low-pressure flow applications, this pipe is also known as Schedule 40.

304 stainless steel pipe offers very good corrosion resistance. 316 stainless steel pipe has excellent corrosion resistance.

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