About Pipe and Fittings
Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
Thick-Wall Aluminum Unthreaded Pipe Nipples and Pipe

- For Use With: Air, Oil, Water
- Specifications Met: ASTM B241
- Fittings: Use Schedule 80 aluminum
The strongest aluminum pipe we offer, this pipe is also known as Schedule 80. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak. Pipe is seamless so it has a smooth interior for unrestricted flow. It is aluminum, which is lightweight with good corrosion resistance.
