Abstract

A flat sealing gasket includes an opening defined by a gasket edge and a sheet metal armor framing the gasket edge. The armor at least partially encloses an annular space which is situated radially inwardly of the gasket edge and is generally concentric with the gasket opening. Further, a graphite filling is accommodated in the annular space.
