Standard-Wall Brass and Bronze Threaded Pipe Nipples and Pipe

Also known as Schedule 40, this pipe is for use in low-pressure flow applications. It is brass, which offers good corrosion resistance.

Pipe Adapters—Fully Threaded

Male

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

Seamless—Pipe has a smooth interior for unrestricted flow and is stronger than welded pipe.

NSF/ANSI 61—To adhere to safety standards for drinking water systems, use pipe that meets NSF/ANSI 61.
