This disclosure is directed to a flexible fluid conduit means for directing fluid from a pressure source to a propeller of a ship for minimizing cavitation. The conduit is formed of split annular rings adapted to be mounted over a propeller shaft, the rings being interconnected to form passages for directing air pressure from the A-bracket through relative rotating seal members and into the body of the propeller. The disclosed interconnection of the annular rings permits substantial axial and bending movement of the propeller shaft without loss of air. Being submersed, the conduit is hydraulically balanced such that the force of water pressure tending to open the seal members is always less than the force tending to close the seal members.
