An improved subsea hanger and seal having a hanger body with an external landing shoulder and an upstanding sealing rim with external sealing teeth and multiple internal camming surfaces and an actuating ring which fits within the sealing rim and includes external multiple camming surfaces mating with the camming surfaces on the interior of the sealing rim to move said sealing rim into initial set position and allow subsequent pressure to be applied to the interior of the actuating ring to deform the sealing rim into positive gripping and sealing engagement with the interior of the subsea wellhead housing in which the hanger is landed. |
