Tungsten Carbide Straight Bore Nozzle – Gun Insert, 7/16″ Bore, 1-1/8″ Flange x 1-3/8″ Length

Part Number: 501-351
Category: Sandblasting & Abrasive Nozzles
Type: Tungsten Carbide Straight Bore Nozzle – Gun Insert, 7/16″ Bore, 1-1/8″ Flange x 1-3/8″ Length

The 501-351 Tungsten Carbide Straight Bore Nozzle is a heavy-duty gun insert built for high-output abrasive blasting applications that demand maximum durability and consistent performance. Featuring a large 7/16″ straight bore with a 1-1/8″ flanged profile and 1-3/8″ overall length, this nozzle delivers high-volume media flow for rapid surface coverage while maintaining a focused, uniform blast pattern. Constructed from premium tungsten carbide, it offers exceptional resistance to erosion and abrasive wear, dramatically outlasting ceramic and steel alternatives in continuous-duty environments. Commonly used as an OEM replacement in Empire Abrasive systems, the 501-351 provides professional-grade reliability for industrial and production blasting operations.
