A pressure actuated seal carrier assembly includes a seal carrier with a body with an inner and an outer projection that are integral with the body and opposite to one another. An inner groove with a first seal is formed in the inner projection, and an outer groove with a second seal is formed in the outer projection. As pressure enters the cavity, the projections are forced radically outward and inward, which maintains contact with the mating surfaces, thus excluding any no extrusion gaps between the seal carrier and the walls of the pressurized space. A spacer is located in the cavity to maintain space between the grooves and bear the axial load.
