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.
Claims15
An electrically isolating gasket comprising:
- a metallic gasket core, the metallic gasket core having a disc shape and including opposed faces separated by an axial height and an inner core surface extending along the axial height between the opposed faces having a first, non-linear shape, wherein the metallic gasket core includes a radially outer groove and a radially inner groove in each of the opposed surfaces of the metallic gasket, and wherein the radially outer groove and the radially inner groove of each of the opposed surfaces are aligned;
- and
- a coating formed on all of the surfaces of the metallic gasket core including the opposed faces and the inner core surface, the coating comprising a dielectric material.
An electrically isolating gasket comprising:
- a retainer formed from a conductive material, the retainer having opposed axial faces and a concave shaped inner retainer surface forming a groove extending between the opposed axial faces;
- a metallic ring seal having an outer ring surface with a convex shape to cooperatively engage the concave shaped inner retainer surface forming a groove;
- and
- a coating formed on all surfaces of the retainer formed from the conductive material including the opposed axial faces and the concave shaped inner retainer surface forming the groove and the metallic ring seal, wherein the coating comprises a continuously applied dielectric material.
