Tungsten Carbide Big Gun Long Venturi Nozzle – 5/16″ Bore, 1-1/4″ Entry, 1-1/4″ NPSM Brass Thread, Poly Jacket

Part Number: 888-5001-305PB
Category: Sandblasting & Abrasive Nozzles
Type: Tungsten Carbide Big Gun Long Venturi Nozzle – 5/16″ Bore, 1-1/4″ Entry, 1-1/4″ NPSM Brass Thread, Poly Jacket

The 888-5001-305PB Tungsten Carbide Big Gun Long Venturi Nozzle is engineered for professional abrasive blasting operations that demand high performance, efficiency, and durability. Its Big Gun long venturi profile accelerates abrasive media more efficiently than standard straight-bore designs, delivering higher particle velocity, improved coverage, and faster surface preparation. The 5/16″ bore offers an ideal balance of airflow and media volume for consistent, controllable blasting, while the tungsten carbide liner provides exceptional wear resistance for long service life. A rugged poly jacket protects against impact and jobsite abuse, making this nozzle a reliable choice for continuous industrial use.
