Any machinist out there that can make a stainless bung for my keg gas tank? Bought the moon filler cap and bung but my keg is stainless and I wasn't sure if the bung they sold was aluminum or mot. It is. I meed a 2 1/4 threaded bung out of stainless for my project. Please let me know if any one cam make something like this and what you would charge. I have pics of what I meed. Thanx !
