Abstract
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.
Claims58
A gasket for creating a seal between a pair of surfaces, said gasket comprising a base sheet having an adhesive element as an edge coating on at least one edge, said adhesive element being adapted to bond with said surfaces to enhance the seal provided by said gasket.
A gasket as in claim 17 wherein said base sheet is a non-compressible carrier.
A gasket as in claim 41 wherein said non-compressible carrier is selected from the group consisting of hard plastic and metal.
A gasket for creating a seal between a pair of surfaces, said gasket comprising
- a non-compressible carrier as a base sheet having at least one edge forming a boundary of a gasket aperture and having at least one face comprising a recess;
- and
- at least one adhesive element as a bead structure disposed in said recess, said adhesive element being adapted to bond with at least one of said surfaces to enhance said seal provided by said gasket.
A gasket for creating a seal between a pair of surfaces, said gasket comprising,
- a non-compressible core having an interior edge;
- a coating of material that is at least partially compressible;
- and
- an adhesive element applied on at least one face of said gasket in an area adjacent to said interior edge of said non-compressible core.
A gasket for creating a seal between a pair of surfaces, said gasket comprising,
- an o-ring having an adhesive element.
