Thick-Wall Brass Threaded Pipe Nipples and Pipe
A thick wall gives this Schedule 80 pipe the strength to handle high-pressure applications. It is brass for good corrosion resistance. Pipe is seamless so it 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.
