Abstract:
1. A seal assembly for sealing to a tubular member, comprising: an annular metal seal body having a leg with a base and a tip; a sealing area on an outer surface of the leg proximate to the tip for sealing engagement with a tubular member; a support area on the outer surface between the base and the sealing area, the support area configured to contact the tubular member but exert less force against the tubular member than the sealing area exerts against the tubular member; a first recess formed on the outer surface of the leg and extending from the support area to the sealing area; a cylindrical portion on the outer surface of the leg proximate the base and having a seal groove containing an elastomeric seal ring; and a second recess formed on the outer surface of the leg between the cylindrical portion and the support area, wherein the first recess has a length, measured along an axis of the seal body, that exceeds a length of the sealing area.
