Boron Carbide Nozzle – Straight Bore, Wide Spray Gun Insert, 5/16" Bore, 7/8" OD x 2-3/4" Length

Part Number: 1348-590
Weight: 0.37 lbs

The Boron Carbide Straight-Bore Nozzle (1348-590) is a high-durability blasting nozzle designed for wide-spray gun applications requiring a larger 5/16-inch bore for increased abrasive flow and faster surface coverage. Engineered with a 7/8-inch outer diameter and 2-3/4-inch overall length, this insert delivers precise, consistent performance in demanding industrial blasting environments.

Constructed from premium boron carbide, one of the hardest and most erosion-resistant materials available, this nozzle offers exceptionally long service life—ideal for high-volume contractors looking to reduce downtime and maximize productivity.
