Copper and hydrosulfuric acid (hydrogen sulfide and water) will definitely have a chemical reaction, right?:)

Copper gaskets are prohibited in the presence of hydrogen sulfide and ammonia

For high-pressure applications, an expansion graphite gasket with 314L material for the inner ring and 20# steel for the outer ring can be used. For low pressure, an asbestos gasket will suffice.
