An undersea hydraulic coupling having a metal seal with a Y-shaped cross section that provides a face type seal between the male and female coupling members is disclosed. The inner circumference of the Y-shaped seal remains engaged with the face of the male member even when there is partial separation of the members, without any pre-loading devices. If the male member is partially removed from the female member bore, a face-type seal is maintained with the face of the male member and a sliding radial seal is maintained with the receiving chamber wall. The seal slides with the male member as it is partially withdrawn from the female member receiving chamber.
