Double Jacketed Gasket (DJG) is made from graphite, ceramic non-asbestos etc. filler covered with thin metal jacket ,such as stainless steel, carbon steel ,copper etc. By their sealing efficienty. provide outstanding resilience, while the metal jacket guarantees excellent sealing and protects the filler against pressure conditions. fluctuating temperatures and corrosion.
DJG is particularly suitable for sealing flat surfaces of heat exchanges, gas pipes cast iron flanges,cylinder heads of engines,as well as for boilers  and other vessels

The double-jacketed corrugated gasket is an improvement on a plain jacketed gasket in that the corrugations on the gasket will provide an additional labyrinth seal. It also provides the advantage of reducing the contact area of the gasket, enhancing its compressive characteristics. A double-jacketed corrugated gasket still relies on the primary seal on the inner lap.

At temperatures in excess of the range of 480°C to 550°C where the standard soft filler is normally not recommended, a double-jacketed corrugated metal gasket with a corrugated metal filler can be beneficial. This construction has the advantages of the double-jacketed corrugated metal gasket,and  in addition, since the filler is normally the same material as the gasket itself, the upper temperature limit would be determined by the metal being used. This type of gasket, depending upon metal selected, is designed to be a heat exchanger gasket for high pressure, high temperature applications.
