Boron Carbide Venturi Nozzle 4.5 mm

Boron Carbide Venturi Nozzle for Abrasive Blasting

This venturi nozzle is manufactured from boron carbide, one of the hardest materials available for blast nozzles, second only to diamond. The venturi internal geometry accelerates abrasive particles to supersonic speeds, creating a tight, consistent blast pattern. The 4.5 mm bore size is a common choice for medium-duty blasting applications where a balance of impact energy and abrasive consumption is required.

Boron carbide nozzles are particularly effective with aggressive media such as aluminum oxide, silicon carbide, and garnet. Their lightweight nature also reduces operator fatigue in manual blasting operations. The nozzle's wear characteristics mean the bore diameter will gradually increase over time, which alters the blast pattern and air consumption. Regular inspection of the orifice is recommended to maintain optimal blasting efficiency.

Compatibility and Replacement

This nozzle is designed as a spare part for standard suction and pressure blast cabinets and portable blasting pots. The thread type and entry profile must match your existing nozzle holder. Common holder types include contractor-style and flat-back configurations. Before ordering, verify the thread size and pitch of your blast machine's nozzle holder to ensure a correct fit. SPA2Z can assist with compatibility checks if you provide your machine model or holder specifications.
