ABSTRACT OF THE DISCLOSURE A wellhead assembly has a metal seal that accommodates misalignment between casing and the bore of the wellhead housing. The metal seal assembly includes a metal seal ring and a wedge ring. The seal ring has a cylindrical inner wall and a conical outer wall. The centerlines of the inner and outer walls are offset with respect to each other, making the ring eccentric. Similarly, the wedge ring has a conical inner wall and an outer wall. Its inner and outer walls are offset with respect to each other. The rings can be rotated relative to each other and to the casing to coincide the axis of the outer wall of the wedge ring with the axis of the wellhead housing bore. The inner wall of the seal ring has protruding bands which deform as a result of the softness of the metal to enhance sealing.
