hi i am using copper gaskets top and botton on my jug do i need to spray anything on gaskets before i install them ie grease,silicone. are copper gaskets good to use as a base gasket?
He is a U.S seller and good to deal with. He will cut any thickness and any other gaskets you would need. Copper is good because it is reusable. You only need to anneal it before another use. It may be the last and only base gasket you ever need.
