ABSTRACT OF THE DISCLOSURE A hydraulic seal for an electrostatic spray coating gun for applying coating materials which have high to moderately high electrical conductivity is disclosed. The gun has an improved high voltage electrical system, improved hydraulic seals, and is adaptable to apply porcelain enamel coatings in slurry form. An electrode is positioned forward of a flat-fan spray nozzle and is displaced from the axis of the spray by means of an extension assembly which can be angularly displaced about the axis of the spray. The gun further incorporates the improved packingless bellows sealing between an opening into the coating conduit in the barrel of the gun and a control rod for a needle valve in the conduit. Novel static seals allow the use of a bellows in the form of a non-machined extruded fluorinated hydrocarbon commonly known as TFE*Teflon. The packingless seals, properly designed flow passages, the position of the charging electrode, and wear resistant material at the nozzle tip and needle valve allow the gun to be used not only for the electrostatic spraying of the common electrically conductive coating materials, but also for abrasive coating materials, such as glazes, in slurry form. * - Trade Mark
