Standard-Wall Butt-Weld Aluminum
Unthreaded Pipe Fittings
Also known as Schedule 40 fittings, these have thicker walls than our thin-wall aluminum unthreaded pipe fittings. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow. Fittings are lightweight with good corrosion resistance.

- For Use With: Air, Oil, Water
- Specifications Met: ANSI/ASME B16.9
- Pipe: Use Schedule 40 aluminum
- Flanges: Use Class 125 aluminum

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.
