How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

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.

Thin-Wall Butt-Weld Aluminum Unthreaded Pipe Fittings
Also known as Schedule 10 fittings, these are the thinnest aluminum pipe fittings we offer. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow. Fittings are lightweight and have 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.
