Metal Jacketed gaskets, as the name suggests, are comprised of a metallic outer shell with either
a metallic or non-metallic filler. The filler material gives the gasket resilience, while the metal
jacket protects the filler and resists pressures, temperatures and corrosion.
They are traditionally used for Heat Exchanger applications, pumps and Valves, however the
resilience and recovery properties of these gaskets are limited. Metal Jacketed gaskets require
smooth flange surface finishes, high bolt loads and flange flatness in order to seal effectively.
There are many different styles of jacketed gaskets available. In the main Menu "Others" you will find a
link to the dimensions of double jacketed flange gaskets. In that type the filler material is completely
enclosed by a two piece metal jacket, which covers both the inside and outside diameters and both
contact surfaces.
