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

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