Abstract
A metal seal for sealing the male end of a tube into the female end of another tube, particularly in a subsea well installation. An annular metal lip is located on the exterior of the male end of the tube. The lip has a free end with a radially protruding metal band. The band has an outer diameter greater than the inner diameter of the female tube bore, providing an interference fit. An annular recess is located inward from the lip, allowing the lip to deflect and exposing the inner portions of the lip to pressure in the bore to act outwardly on the lip.
