<p>A probe member for an undersea hydraulic coupling is disclosed having at least one circumferential depression in its outer cylindrical body, for disengaging one or more radial seals during insertion or withdrawal of the probe member from the receiving member of a coupling. The disengagement of the radial seals allows seawater to bleed from or into the space between the coupling members and thereby balance the coupling and seals to seawater pressure.</p> |
