Thick-Wall Aluminum Threaded Pipe Nipples and Pipe
Also known as Schedule 80, this pipe has extra-thick walls to handle high-pressure applications. It is seamless so it has a smooth interior for unrestricted flow. Pipe is aluminum, which is lightweight with good corrosion resistance.
Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.
