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

    Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.
    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.
    Seamless—Pipe has a smooth interior for unrestricted flow and is stronger than welded pipe.
