A sterilizable medical/dental syringe having a handle with a nozzle at one end is provided with means for releasably coupling the other end of the handle to a flexible supply hose providing compressible gases and/or noncompressible liquids. When disconnected from the flexible hose supply line, automatic sealing valves prevent the contents of the supply line from escaping. A readily repairable flow control valve for the nozzle is also disclosed.
