About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Thin-Wall Stainless Steel Unthreaded Pipe Nipples and Pipe

Also known as Schedule 10, this pipe is thin and lightweight. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak.

Pipe—Unthreaded

304/304L Stainless Steel—Pipe holds up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.

316/316L Stainless Steel—Pipe is the most corrosion resistant. It stands up to wet environments, just like 304 stainless steel pipe, but unlike 304 stainless steel, it will not corrode from salt water, chlorine solutions, and chemicals.

Welded—Pipe has a weld bead on the inside.
