Nozzle – Boron Carbide Long Venturi, 3/8" Bore, 1" Entry, 1-1/4" NPSM Thread, Aluminum Jacket

Part Number: 101-4210
Weight: 1.00 lbs

The 101-4210 Boron Carbide Long Venturi Nozzle is a premium, ultra-durable blasting nozzle engineered for maximum service life and consistent performance in high-production abrasive blasting environments. Featuring a boron carbide liner, one of the hardest and most wear-resistant materials available, this nozzle is ideal for use with extremely aggressive abrasives such as aluminum oxide, silicon carbide, and steel grit.

The 3/8" bore provides a fast, focused, high-velocity blast stream suitable for industrial cleaning, rust and scale removal, coating removal, and structural steel surface preparation. Its long venturi design significantly increases abrasive acceleration and widens the blast pattern, maximizing cleaning speed while reducing abrasive consumption.

A lightweight yet strong aluminum jacket protects the nozzle liner, while the 1-1/4" NPSM threaded connection ensures compatibility with standard heavy-duty nozzle holders.

⚠️ WARNING: Aluminum-threaded nozzles should not be used with aluminum nozzle holders, as they may seize or become inseparable.
