Metal to metal wedge ring seal

A seal assembly, comprising:

• an outer member defining a bore;
• an inner member received in the bore of the outer member and one of the outer member and the inner member defining a shoulder portion;
• a first circular cross section ring member having a first inner diameter and a first outer diameter, the first circular cross section ring member being disposed between the inner member and the outer member and directly against the inner member;
• a second circular cross section ring member having a second inner diameter and a second outer diameter that are larger than the first inner diameter and the first outer diameter, respectively, the second circular cross section ring member being disposed between the outer member and the first circular cross section ring member and directly against the outer member;
• and
• a wedge member engaging the first circular cross section ring member and the second circular cross section ring member for applying an axial force against each of the first and second circular cross section ring members in a direction toward the shoulder portion and for applying a radially outer force against the second circular cross section ring member and for applying a radially inner force against the first circular cross section ring member.
