Claim:
1. A system, comprising: a seal assembly configured to seal between a first tubular component and a second tubular component of a mineral extraction system, the seal assembly comprising: a metal-to-metal seal comprising a first annular portion coaxial with a second annular portion and interfacing one another along respective frustoconical surfaces; a first sleeve disposed on a first axial side of the metal-to-metal seal, wherein the first sleeve is configured to be disposed within the first tubular component and between the first tubular component and the second tubular component; a second sleeve comprising an inner surface and an outer surface, wherein the second sleeve is disposed on a second axial side of the metal-to-metal seal opposite from the first sleeve, and wherein the first sleeve is responsive to a hydraulic actuation and movement of a piston to move the first sleeve axially toward the second sleeve to axially compress and radially expand the metal-to-metal seal into a set state relative to the tubular components of the mineral extraction system, and wherein the second sleeve is configured to be disposed within the first tubular component and between the first tubular component and the second tubular component; and a retainer ring coaxial with the first and second sleeves, wherein the retainer ring is configured to move axially independent from the movement of the piston, wherein the retainer ring is configured to move axially in response to rotation to hold the first sleeve in position with respect to the second sleeve such that the metal-to-metal seal remains in the set state.
