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.

Thick-Wall Butt-Weld Aluminum Unthreaded Pipe Fittings
Thick walls give these Schedule 80 fittings excellent strength. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow. Fittings are aluminum, which is lightweight with good corrosion resistance.
