Made from 6061 so welding and anodizing after welding is no issue for the do it yourselfer. Male bung has a 37 degree JIC flare to work with industry standard female fittings.
Bung has a small step on the back side which allows the bung to register in the hole and makes it easy for alignment and to be welded from both sides if the racer chooses.
