Great Price, Great Product
Restoring a vintage Hobart engine driven welding machine, I needed 3” bung 1/4 turn caps for both radiator and fuel tank. The Hobart caps are non-vented so I took a flapper wheel, knocked the zinc coating off around the vent hole and with around 30A DCEN tigged it shut with one dab of filler. Now I have non-vented 3” caps. Very nice caps with knurling. Highly recommend
