Abstract
A nozzle includes a tungsten carbide body and threaded steel sleeve. The nozzle body includes a fluid jet opening arranged to be reoriented in response to rotation of the nozzle body. The nozzle body includes a first set of apertures for receiving a turning tool. The sleeve comprises a split sleeve retained longitudinally upon the nozzle body and is rotatable relative thereto. The sleeve threads are protectively disposed behind a flange of the nozzle body. The sleeve includes a second set of apertures which are alignable with the first set of apertures adjacent an inner end of the latter. The turning tool is engageable with (i) both sets of apertures for rotating the nozzle body and sleeve to install the nozzle, or (ii) with only the first set of apertures to rotate the nozzle body relative to the sleeve against the resistance of an O-ring to reorient the jet opening.
