    Percy's Seal-4-Good Reusable Flange Gaskets are multi-layered and made from a special "Dead Soft" aluminum that conforms to header flanges for the ultimate seal. Because made from multiple layers of dead soft metal, Seal-4-Good easily conforms to small imperfections that copper gaskets simply can't, and these gaskets will not blow out or burn out when properly installed.
