Graphite gaskets designed for use in vacuum casting applications, providing a reliable seal at the flange and casting chamber. The graphite material withstands temperatures up to 1200°F (649°C), making these gaskets well-suited for the demanding conditions of investment casting. Graphite gaskets are exceptionally long-lasting and remain functional even as they wear down to near paper-thin thickness — as long as they are handled carefully to avoid cracking or breakage.
