Abstract

In order to produce a gasket that is adapted to be arranged between two components requiring sealing of which at least one contains a first metallic material which is less noble than aluminium and the gasket comprises at least one gasket layer including a plate consisting of a second metallic material which is nobler than the first metallic material, such that contact corrosion on the components requiring sealing is reduced or completely prevented, it is proposed that the gasket layer should comprise a sealing element which is arranged at an outer boundary region of the plate, should consist of an elastomer material and, in the installed state of the gasket, should gasket the gap between the gasket layer and the component which contains the first metallic material in a substantially fluid-tight manner.
