Double Venturi Nozzle with Tungsten Carbide internal materials, offers a 35% larger blast pattern than a standard Long Venturi. This is accomplished with only a slight loss in abrasive velocity. These nozzles are designed to be used on jobs where medium cutting action is required. They offer a more even dispersion of abrasive throughout the larger blast pattern. Excellent for plastic or agricultural abrasives. Also great when anodizing or powder coating.
