A seal assembly comprising: a sealing component and a spring energizer; said sealing component comprising two sealing flanges (120, 122) defining a seal cavity, a seal lip (124, 126) located on each of the two sealing flanges (120, 122), and a cover flange having an exterior surface and an interior surface; said spring energizer positioned within said seal cavity for biasing the two sealing flanges (120, 122) away from one another to provide a load onto said seal lips (124, 126) for sealing against two different surfaces; wherein radial-end-most surfaces (120c, 122c) of the two sealing flanges (120, 122) define an inside diameter of the sealing component; Characterized in that wherein each of the two sealing flanges (120, 122) has a base (120a, 122a) attached to the cover flange and a remote flange arm portion (120b, 122b) extending from the base (120a, 122a) and remote from the cover flange; wherein the base (120a, 122a) of each sealing flange (120, 122) has a thickness and the remote flange arm portion (120b, 122b) of each sealing flange (120, 122) has a thickness that is larger or thicker than the thickness of the base (120a, 122a); wherein the exterior surface is configured to be exposed to the atmosphere when in service; and wherein flange overhangs (148, 150) extend axially of a central part of the cover flange and axially of the two sealing flanges (120, 122) for providing cover for said seal cavity and said spring energizer and a flange stub extends radially from the interior surface of the cover flange towards a centerline of said sealing component, contacts the spring energizer, and pushes the spring energizer away from the interior surface of the cover flange towards said centerline; or said spring energizer having portions that extend externally of the seal cavity towards a centerline of said sealing component. said sealing component comprising two sealing flanges (120, 122) defining a seal cavity, a seal lip (124, 126) located on each of the two sealing flanges (120, 122), and a cover flange having an exterior surface and an interior surface; said spring energizer positioned within said seal cavity for biasing the two sealing flanges (120, 122) away from one another to provide a load onto said seal lips (124, 126) for sealing against two different surfaces; wherein radial-end-most surfaces (120c, 122c) of the two sealing flanges (120, 122) define an inside diameter of the sealing component; Characterized in that wherein each of the two sealing flanges (120, 122) has a base (120a, 122a) attached to the cover flange and a remote flange arm portion (120b, 122b) extending from the base (120a, 122a) and remote from the cover flange; wherein the base (120a, 122a) of each sealing flange (120, 122) has a thickness and the remote flange arm portion (120b, 122b) of each sealing flange (120, 122) has a thickness that is larger or thicker than the thickness of the base (120a, 122a); wherein the exterior surface is configured to be exposed to the atmosphere when in service; and wherein flange overhangs (148, 150) extend axially of a central part of the cover flange and axially of the two sealing flanges (120, 122) for providing cover for said seal cavity and said spring energizer and a flange stub extends radially from the interior surface of the cover flange towards a centerline of said sealing component, contacts the spring energizer, and pushes the spring energizer away from the interior surface of the cover flange towards said centerline; or said spring energizer having portions that extend externally of the seal cavity towards a centerline of said sealing component.
