There is provided a gasket comprising a rigid core () defining an aperture (). The core has a serrated profile () on at least one of its upper and lower outer surfaces and the core is divided into upper and lower parts () each having a respective outer surface () and also an inner surface () opposite the outer surface. The gasket also includes an optional sealing facing () on the at least one outer serrated profile surface, wherein an inner insulating layer () is located between the said upper and lower parts so that it is operable to substantially reduce electrical conduction between the said upper and lower parts. There is described a method of production of the gasket and use of the gasket.

Gasket

There is provided a gasket () for sealing two mating surfaces, the gasket comprising: a rigid non-metal core () defining an aperture (), the core comprising a first face () extending away from the aperture and a second face () opposite the first face; and at least one sealing layer (); wherein the first face comprises: a substantially flat inner region () defining a plane; and a serrated region () comprising a plurality of serrations () that extend substantially perpendicular to the plane, wherein the substantially flat inner region is located between the aperture and the serrated region, wherein the serrations are recessed in the first face such that they do not cross the plane, wherein the at least one sealing layer overlays at least part of the serrated region of the first face.
