Manufacturing Since 1853


We have been a manufacturer of metal stampings for more than 160 years.  Today, we have a standard line of threaded parts that we refer to as “Welding Flanges”.  Other people may call them by other names such as: bungs, pressings and bosses, just to name a few.  Essentially they are very similar in function to a half coupling but dimensionally they have a lower profile and pilot into the tank through a punched hole.  They have excellent welding compatibility because they are manufactured from slit coil raw material, which is the same material as the tank skin.
