Boron Carbide Medium Venturi Nozzle – 3/8″ Bore, 1″ Entry, 1-1/4″ NPSM Thread, 4-1/8″ Length, Steel Jacket

Part Number: 502-302
Category: Sandblasting & Abrasive Nozzles
Type: Boron Carbide Medium Venturi Nozzle – 3/8″ Bore, 1″ Entry, 1-1/4″ NPSM Thread, 4-1/8″ Length, Steel Jacket

The 502-302 Boron Carbide Medium Venturi Nozzle is designed to deliver higher blasting efficiency than straight-bore nozzles while maintaining excellent control and durability. Its medium venturi profile accelerates abrasive media more effectively, increasing particle velocity and improving coverage for faster, more uniform surface preparation. The 3/8″ bore provides strong cutting power with controlled airflow, making it ideal for light-to-medium duty industrial blasting. A boron carbide liner offers exceptional wear resistance—often outlasting ceramic and tungsten carbide in fine-abrasive environments—while the rugged steel jacket protects against impact and harsh jobsite conditions. With a 4-1/8″ body length and standard 1-1/4″ NPSM threads, this nozzle installs securely in professional blast systems for consistent, repeatable performance.
