Crush Gaskets | McMaster-Carr

Made of 110 copper, these gaskets handle steam applications up to 600° F. They are electrically conductive and resist water, Freon, and fuel oil. The metal construction provides structural strength. These gaskets can be used with both flat-surface and raised-surfaces pipe flanges; they fit the surface inside the bolt holes and do not interfere with the bolt connection.
