Worn nozzles cost money! We recommend you replace your nozzles when they wear out 1/32 of an inch, this is 1/2 a size…

A venturi blast nozzle interior has a shape and length specifically designed for it’s orifice size. This is to ensure optimum performance and efficiency. A worn nozzle is more costly to use for two reasons…

  • A bigger orifice requires more compressed air to maintain a desired pressure.
  • The even spread of abrasive across the blast pattern deteriorates as the blast nozzles wears.

To check the amount of wear in your nozzle…

  • Mark the rear of the engraved section of the gauge with a crayon.
  • Insert the gauge into the rear of the nozzle (threaded end).
  • Orifice size can be determined by observing the highest orifice size marking from which the crayon has been removed.
