Looking for a place that sells weld in air tank bungs

[ARAMP1]

I have an air tank that has a .5" NPT fitting on it and I need a 1.25" NPT fitting. Does anyone know of any place around that sells bungs that I could weld in? Earls weld in only goes up to .75" and Russells only goes to 1". I googled the hell out of this with no luck.

EDIT: Found them.

I'd say McMaster-Carr would be your best bet. They ship super fast too...
