Boron Carbide Nozzle – Straight Bore Gun Insert, 3/8" Bore, 7/8" OD x 1-3/8" Length

Part Number: 1348-640
Weight: 0.09 lbs

The Boron Carbide Straight-Bore Gun Insert (1348-640) is a compact, heavy-duty blasting nozzle engineered for applications requiring a 3/8-inch bore for high abrasive flow and efficient material removal. With a 7/8-inch outer diameter and a short 1-3/8-inch overall length, this nozzle is ideal for tight-clearance gun bodies and high-demand blasting environments where durability, precision, and performance are critical.

Constructed from ultra-hard boron carbide, this nozzle delivers superior wear resistance and long service life, significantly reducing downtime and replacement costs in continuous-use industrial applications.
