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.

Thin-Wall Aluminum Unthreaded Pipe Nipples and Pipe
- For Use With: Air, Oil, Water
- Fittings: Use Schedule 10 aluminum
Also known as Schedule 10, this pipe has the thinnest walls of all our aluminum pipe. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak. Pipe is seamless, which provides a smooth interior for unrestricted flow. It is lightweight with good corrosion resistance.

Thin-Wall Socket-Connect Aluminum Unthreaded Pipe Fittings
Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection. Fittings are aluminum, which is lightweight with good corrosion resistance.
