This Premium Turbo Nozzle features a spring loaded pin to seal the end of the nozzle keeping out sand and mud that causes competitors' nozzles to fail. This feature also allows you to engage the turbo nozzle in any direction without the risk of damaging the internal ceramic pin or seat. As with all turbo nozzles, the RotoJet has a laser nozzle that spins at an incredible rate increasing your cleaning area from zero degrees to 26°.
