Boron Carbide Straight Bore Nozzle – 3/16″ Bore, 3/4″ Entry, 1-1/4″ NPSM Thread, 3-1/4″ Length, Steel Jacket

Part Number: 502-142
Category: Sandblasting & Abrasive Nozzles
Type: Boron Carbide Straight Bore Nozzle – 3/16″ Bore, 3/4″ Entry, 1-1/4″ NPSM Thread, 3-1/4″ Length, Steel Jacket

The 502-142 Boron Carbide Straight Bore Nozzle is designed for precision abrasive blasting where control, durability, and consistent performance are essential. With a 3/16″ straight bore, this nozzle produces a focused, high-velocity blast stream ideal for detailed surface preparation and light-to-medium duty applications. The boron carbide liner delivers exceptional wear resistance—often outlasting ceramic and tungsten carbide in fine-abrasive environments—while the rugged steel jacket protects against impact and jobsite abuse. Its extended 3-1/4″ body and standard 1-1/4″ NPSM threads ensure stable mounting and compatibility with professional blast systems.
