Sandblasting Nozzle Sizing Chart

 

Use The Chart Below To Find Your Nozzle Bore Size:

  • #2 Nozzle has a 1/8" orifice (3.2mm)
  • #3 Nozzle has a 3/16" orifice (4.8mm)
  • #4 Nozzle has a 1/4" orifice (6.35mm)
  • #5 Nozzle has a 5/16" orifice (8mm)
  • #6 Nozzle has a 3/8" orifice (9.5mm)
  • #7 Nozzle has a 7/16" orifice (11.1mm)
  • #8 Nozzle has a 1/2" orifice (12.7mm)
  • #10 Nozzle has a 5/8" orifice (16mm)
  • #12 Nozzle has a 3/4" orifice (19mm)

Use The Chart Below To Find Your Minimum Nozzle Bore Size For Different Blasting Grits:

  • 3060 grit = Minimum nozzle bore size of 1/8″
  • 2040 =  Minimum nozzle bore size of 3/16″
  • 16/20, 1240 = Minimum nozzle bore size of 1/4″
  • As a general rule, your nozzle orifice should be 3 times the size of the grit, MINIMUM.
