2)length :130-230mm
Coarse thread long venturi boron carbide rubber jacket sand blast nozzles
Boron carbide nozzles offer the longest wear life of any standard nozzle material.
Peak nozzle production performance is maintained for longer periods with optimum consumption of air
and abrasive. Boron carbide nozzles typically outwear tungsten carbide nozzles by five to ten times
and silicon carbide by two to three times. Boron carbide nozzles are recommended for use with abrasives
such as aluminum oxide and aggressive mineral aggregates.
Our selection of nozzles is unmatched, anywhere
We have standard products that can replace the original nozzles installed on most equipment.
We also have higher performance upgrades for most OEM products to allow you to achieve optimum
blasting effectiveness, efficiency and reduce your total costs.
