Add a female AN port to any aluminum tank with these 6061-T6 aluminum weld-in fittings. A 1/8" deep flange at the base makes welding easier without hindering flow or drainage. Sold individually.

These weld bungs are designed to be sealed with an O-Ring (Part No. 3244, sold separately). We offer a variety of O-Ring Boss to AN Adapters as well.

The top photo shows the inside (weld chamfer side) of the bung. The bottom photo shows the exposed end (O-ring chamfer side). Bungs are sold individually.
