Nozzle – Boron Carbide Long Venturi, 1/4" Bore, 1" Entry, 1-1/4" NPSM Thread, Aluminum Jacket

Part Number: 101-4190
Weight: 0.90 lbs

The 101-4190 Boron Carbide Long Venturi Nozzle is engineered for maximum durability and long-term blasting performance. Boron carbide is one of the hardest nozzle materials available—providing exceptional wear resistance and outperforming tungsten carbide, SiAlON, and alumina-based liners in abrasive longevity. This makes it the premier choice for high-volume contractors and operators using aggressive abrasives such as silicon carbide, aluminum oxide, or steel grit.

The long venturi design delivers maximum acceleration of abrasive media, producing a fast, uniform, and wide blast pattern that increases productivity and reduces overall abrasive consumption. The 1/4" bore creates a controlled, focused stream ideal for precision blasting while still maintaining high velocity. The aluminum jacket keeps the nozzle lightweight and easy to handle, while the 1-1/4" NPSM thread ensures compatibility with standard industrial nozzle holders.

⚠ WARNING: Nozzles with aluminum threads should not be paired with aluminum nozzle holders, as the metals can seize and become inseparable.
