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

Part Number: 502-172
Category: Sandblasting & Abrasive Nozzles
Type: Boron Carbide Straight Bore Nozzle – 3/8″ Bore, 3/4″ Entry, 1-1/4″ NPSM Thread, 3-1/4″ Length, Steel Jacket

The 502-172 Boron Carbide Straight Bore Nozzle is engineered for controlled, high-precision abrasive blasting in light-to-medium duty applications. With a 3/8″ straight bore, this nozzle delivers a focused, high-velocity stream that provides strong cutting power while maintaining excellent control. Its boron carbide liner offers 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 extended 3-1/4″ body and standard 1-1/4″ NPSM threads ensure stable mounting and compatibility with professional blast systems.
