Patent number: 7278639Abstract: An edge coated gasket includes a base sheet made of compressible gasket material and having opposed faces and an interior edge surrounding and defining an aperture. An edge coating of polymer or other material is disposed on and seals the interior edge of the base sheet and may project beyond the facial planes of the base sheet to define protruding rims extending around the aperture. Face coatings may also be applied to one or more of the faces extending in relatively narrow strips around the aperture of the base sheet. When clamped between flange surfaces, the edge coating engages, conforms to, and seals against the flange surfaces to provide a seal against both interfacial and intersticial migration of fluid past the gasket. At the same time, the inherently good compression failure resistance of the compressible gasket material of the base sheet is preserved. Thus, a gasket with enhanced sealability and compression failure resistance is provided.Type: GrantFiled: March 19, 2003Date of Patent: October 9, 2007Assignee: Interface Solutions, Inc.Inventors: John S. Forry, Brian C. Lehr, Dennis M. Dempsey, Jeffery L. Barrall, Linda L. Sload, Christopher L. Morris

Patent number: 6268020Abstract: A gasket having two opposed faces and an edge disposed therebetween is given a wide coating on the edge. The coating is sufficiently wide so that it goes from corner to corner on the edge and protrudes past the corner on at least one side of the gasket in a direction perpendicular to a facial plane of the gasket. The coating protrudes in an amount effective to give the gasket a sealing ability which is better than the sealing ability of the same gasket if it had a coating merely extending from corner to corner without protruding. A process for coating the gasket edges which are around the aperture comprises placing the gasket sheets together so that a cavity is formed by the apertures, the sides of the cavity are the aperture edges to be coated. The coating material is put into the cavity and contacts the edges to be coated to form the coated edges.Type: GrantFiled: July 6, 1998Date of Patent: July 31, 2001Assignee: Interface Solutions, Inc.Inventors: John S.
