US Patent 7163190 Undersea hydraulic coupling member and seal retainer

An undersea hydraulic coupling member having a seal retainer with a first inner ring and a second outer ring is disclosed. The first inner ring and second outer ring are concentric, at least part of the first inner ring inserted through the second outer ring. The second outer ring is threaded to the coupling member to provide sufficient torque to reduce or eliminate any gap between the seal retainer and the shoulder surface in the coupling member on which an elastomeric seal is positioned. Another elastomeric seal is held between the first inner ring and second outer ring of the seal retainer.
