Gaskets with controlled flange surface adhesion properties

摘要

An improved gasket (11) for sealing the joint between a pair of flange surfaces is provided. In one embodiment, the gasket (11) is an edge coated gasket and the edge coating (14) also exhibits surface adhesion to enhance the seal provided by the gasket. In another embodiment, compressible sealing members (34, 44) are coated with a coating material (37, 47) that exhibits surface adhesion properties.
