A female hydraulic coupling member is equipped with an internal displaced water compensation system comprising a spring-biased piston in a generally axial cylinder bored into the coupling body and that is offset from the central axial bore. The cylinder is in fluid communication with an interior portion of the receiving chamber such that seawater within the receiving chamber that is displaced by the probe of a male coupling member inserted in the receiving chamber may move into the cylinder of the displaced water compensation system. During coupling separation, the process is reversed and seawater retained in the displaced water compensation system moves into the receiving chamber under the influence of the spring-biased piston thereby preventing a vacuum.
