Abstract
Gaskets for sealing two mating surfaces are described. The gaskets have an outer portion including a core between two sealing layers and an inner portion made of a deformable material and located in an aperature in the outer portion. The thickness of the inner portion is greater than the thickness of the outer portion. The inner portion may include a chemical treatment agent that can provide chemical protection to the mating surfaces. Methods of producing the gaskets and methods of using the gaskets for sealing joints, including corroded joints, are also described.
