Beautiful MAXX Performance copper gaskets have an embossed O-ring gasket design which increases sealing pressure around exhaust ports to create a tight, leakproof seal, even on irregular surfaces.

Made from long lasting .043” solid copper, these gaskets will not shrink, deteriorate or blowout, so gasket leaks are eliminated!
