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

Part Number: 502-152
Category: Sandblasting & Abrasive Nozzles
Type: Boron Carbide Straight Bore Nozzle – 1/4″ Bore, 3/4″ Entry, 1-1/4″ NPSM Thread, 3-1/4″ Length, Steel Jacket

The 502-152 Boron Carbide Straight Bore Nozzle is engineered for precision blasting applications that require a balance of cutting power, control, and long service life. Featuring a 1/4″ straight bore, this nozzle delivers a concentrated, high-velocity stream ideal for light-to-medium duty surface preparation and detail work. The boron carbide liner offers exceptional wear resistance—often exceeding the lifespan of ceramic and tungsten carbide in fine-abrasive environments—while the rugged steel jacket protects against impact and jobsite abuse. With its extended 3-1/4″ body and standard 1-1/4″ NPSM threads, this nozzle installs easily into professional blast systems and maintains consistent performance over extended use.
