There is provided a reversible spray tip of the type used with a spray device adapted for hydraulically atomizing and spraying liquids, the reversible spray tip includes a rotatable member mounted in the spray tip housing having a diametric bore therethrough terminating in a spray opening, the housing includes an axial bore communicating between the fluid passageway of the spray device and the diametric bore of the rotatable member, a sealing member is mounted in the axial bore of the housing and is provided with an axial fluid bore therethrough communicating between the fluid passageway of the spray device and the diametric bore of the rotatable member, the sealing member includes a resilient sealing washer disposed between the nozzle housing and the sealing face of the spray device. The sealing washer is undercut in the internal sidewall at the inlet end thereof so as to form an annular skirt abutting the sealing face of the spray device. This annular skirt is urged against the sealing face of the spray device by the high pressure fluid in the spray nozzle.
