Abstract: A hybrid gasket includes a core defining an aperture therein, the core having an outer edge portion and an inner edge portion immediately surrounding the aperture. The gasket further includes a chemically resistant material encapsulating the inner edge portion, and an expanded graphite material encapsulating the outer edge portion. A method of sealing two substantially parallel surfaces includes the steps of interposing between the surfaces a gasket, and securing the surfaces to one another. The gasket including a core defining an aperture therein, the core having an outer edge portion and an inner edge portion immediately surrounding the aperture. The gasket further including a chemically resistant material encapsulating the inner edge portion and an expanded graphite material encapsulating the outer edge portion.
