Take a piece of glass or a really flat surface, put a sheet of sand paper down and sand the gasket surfaces, to make sure they are flat. Then maybe a really small dab of RV silicone in a thin coat......Curt

Should I use a gasket with The silicone (cardboard, copper,)? Or just silicone?

The black stock gaskets get brittle quick!

My big block motor home was metal to metal, and set for a few minuets tighten, but you could try the gaskets first. Much easier to change if they work.........Curt
