ABSTRACT:
An undersea hydraulic coupling have a pair of hollow metal seals which are pressure energized to seal between the male and female members of the coupling. One of the hollow metal seals is configured to expand radially while the second hollow metal seal is compressible along the longitudinal axis of the coupling. These seals provide a fluid tight sealing arrangement upon pressurization of the coupling, without the need for external pre-load devices.
