An actuating ring 38 fits within the sealing rim 20 and includes external multiple camming surfaces mating with the camming surfaces 36 on the interior of the sealing rim to move the sealing rim into an initial set position and allow subsequent pressure to be applied to the interior of the actuating ring to deform the sealing rim 20 into positive gripping and sealing engagement with the interior of the subsea wellhead housing 18 in which the hanger 10 is landed.</p> |
