Abstract: An electrically isolating gasket is disclosed wherein a coating layer is disposed on at least one conductive surface, and in some embodiments, on all surfaces or at least all of the conductive surfaces. The electrically isolating gasket includes a core gasket component, a ring seal component, and a non-conductive inner seal component. The coating layer can be, for example, polyimide, polyamide, ceramic, and aluminum oxide.

Abstract: A multi-layered lip seal comprising a dynamic layer optionally having a filler incorporated therein and a static layer optionally having a filler incorporated therein is described. The lip seal has an annular ring shape, wherein an inner diameter of the ring shape is curved in an axial direction so as to give the lip seal a J-shape when viewed from a cross-sectional perspective. Fillers that can be included in static layer include stiffening filler, reinforcement fillers, conductive fillers and/or abrasion resistance fillers. Fillers that can be included in the dynamic layer include wear resistance fillers. The use of specific fillers in specific layers of the multi-layered lip seal allows for certain segments of the lip seal to be imparted with the benefits of the filler without negatively impacting other segments of the lip seal.

Abstract: Gasket seals for high pressure applications include retaining elements with inner diameter seal elements that interlock with the retaining element to provide resistance to movement in both axial and radial directions between the retaining element and seal element. High pressure sealing may be accomplished using a metallic core retaining element to which an electrically isolating material is bonded on either or both sides. Sealing is achieved through an inner diameter dielectric sealing element, such as a polytetrafluoroethylene (PTFE) inner diameter sealing ring. Flanges of a joint in a fluid flow ling may be bolted together with the gasket seal interposed therebetween. In the event of pressure changes, the inner diameter seal resists being drawn into the flow line, and resists axial movement relative to the retaining element, through dual locking members that secure the seal to the retaining element.

Abstract: An electrically isolating gasket is disclosed wherein a coating layer is disposed on at least one surface, and in some embodiments, on all surfaces, of the disc-shaped core gasket component of the electrically isolating gasket. The core gasket component can be made of a metallic material and may include one or more grooves in each axial surface of the core gasket component. When the core gasket component includes such grooves, the coating can be applied to all surfaces of the grooves as well as all other surfaces of the core gasket component so that the coating encapsulates the core gasket component. The coating layer can be, for example, polyimide, polyamide, ceramic, and aluminum oxide.

Abstract: A molded discrete low stress gasket is constructed of restructured filled PTFE for use in corrosive or severe chemical environments under relatively low bolt loads. The gasket has a gasket surface and includes a raised outer sealing ring and a raised inner sealing ring. The gasket may constructed from a restructured filled PTFE material, with the sealing rings deforming at lower pressures than the remaining portions of the gasket.
