A seal assembly comprising: a sealing component and a spring energizer ; said sealing component comprising two sealing flanges defining a seal cavity , a seal lip located on each of the two sealing flanges , 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 away from one another to provide a load onto said seal lips for sealing against two different surfaces; wherein radial-end-most surfaces of the two sealing flanges define an inside diameter of the sealing component ; Characterized in that wherein each of the two sealing flanges has a base attached to the cover flange and a remote flange arm portion extending from the base and remote from the cover flange ; wherein the base of each sealing flange has a thickness and the remote flange arm portion of each sealing flange has a thickness that is larger or thicker than the thickness of the base ; wherein the exterior surface is configured to be exposed to the atmosphere when in service; and wherein [A] flange overhangs extend axially of a central part of the cover flange and axially of the two sealing flanges 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 [B] 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 defining a seal cavity , a seal lip located on each of the two sealing flanges , 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 away from one another to provide a load onto said seal lips for sealing against two different surfaces; wherein radial-end-most surfaces of the two sealing flanges define an inside diameter of the sealing component ; Characterized in that wherein each of the two sealing flanges has a base attached to the cover flange and a remote flange arm portion extending from the base and remote from the cover flange ; wherein the base of each sealing flange has a thickness and the remote flange arm portion of each sealing flange has a thickness that is larger or thicker than the thickness of the base ; wherein the exterior surface is configured to be exposed to the atmosphere when in service; and wherein [A] flange overhangs extend axially of a central part of the cover flange and axially of the two sealing flanges 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 [B] said spring energizer having portions that extend externally of the seal cavity towards a centerline of said sealing component . <EOS>
