Boron Carbide Medium Venturi Nozzle – 1/4″ Bore, 1″ Entry, 1-1/4″ NPSM Thread, 4-1/8″ Length, Steel Jacket

Part Number: 502-282
Category: Sandblasting & Abrasive Nozzles
Type: Boron Carbide Medium Venturi Nozzle – 1/4″ Bore, 1″ Entry, 1-1/4″ NPSM Thread, 4-1/8″ Length, Steel Jacket

The 502-282 Boron Carbide Medium Venturi Nozzle is designed to deliver higher blasting efficiency than straight-bore designs while maintaining excellent control and long service life. Its medium venturi profile accelerates abrasive media more effectively, producing greater particle velocity and improved coverage for faster surface preparation. The 1/4″ bore offers a balanced combination of precision and cutting power, making it ideal for light-to-medium duty blasting. A boron carbide liner provides exceptional wear resistance—often outperforming ceramic and tungsten carbide in fine-abrasive environments—while the rugged steel jacket protects against impact and harsh jobsite conditions. The 4-1/8″ body length and standard 1-1/4″ NPSM threads ensure secure mounting and consistent performance in professional blast systems.
