Abstract:
A dielectric gasket comprising:an outer annular disk having at least one portion formed from a rigid electrically non-conducting material, the outer annular disk having a first face and a second face, an inside diameter surface and an outside diameter surface; an inner annular disk having at least one portion formed from a rigid, electrically non-conducting material, the inner annular disk having a first face and a second face, an outside diameter surface, and an inside diameter surface, the inner annular disk being concentrically disposed within the inside diameter of the outer annular disk; a seal mechanically disposed between the inside diameter of the outer annular disk and the outside diameter of the inner annular disk operable to prevent the transport of gas and liquids from the inner annular disk to the outer annular disk, the seal having a face to face thickness greater than the inner annular disk and the outer annular disk and operable to deform into an available void volume when compressed; the outside diameter surface of the inner annular disk formed to allow the seal to be slidably disposed inside of the outer annular disk and to substantially prohibit relative concentric and axial movement between the outer annular disk and the seal; the inside diameter surface of the seal formed to allow the outside diameter surface of the inner annular disk to be slidably disposed inside of the seal with a fit that substantially prohibits relative concentric and axial movement between the seal and the inner annular disk; the outer annular disk and the inner annular disk having a substantially equal thickness; and the seal operable to bridge the respective faces of the outer annular disk and the inner annular disk.
