Corrugated metal gaskets consist of a metal core with concentric grooves on both sides and coated with flexible graphite or PTFE. The gasket offers the strength of metal gaskets combined with the excellent microsealing qualities of graphite. The corrugated surfaces enable the gasket to adapt to irregular flange surfaces even under lower loads and fluctuating temperatures and pressures. These gaskets can be custom made in any suitable metal type.
Corrugated metal gaskets have a wide application range and are especially suited for use in higher temperature environments than soft gaskets.
