The Tungsten Carbide Double Venturi Nozzle:

The tungsten carbide double venturi nozzle 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.  These nozzles feature a steel jacket and aluminum 1-1/4″ threads with a Tungsten Carbide core.
