A seal assembly for providing reliable sealing between a subsea wellhead and a casing hanger suspended within the wellhead which provides a metal band between the top and the bottom of the seal section for strength, setting force acting against the portion of the seal outside of the metal band, collapsing of the metal band by pressure generated in the portion of the seal, and the movement of the metal band setting the seal within the seal onto the casing hanger.
