Tungsten Carbide Big Gun Long Venturi Nozzle – 3/8″ Bore, 1-1/4″ Entry, 1-1/4″ NPSM Brass Thread, Poly Jacket

Part Number: 888-5001-306PB
Category: Sandblasting & Abrasive Nozzles
Type: Tungsten Carbide Big Gun Long Venturi Nozzle – 3/8″ Bore, 1-1/4″ Entry, 1-1/4″ NPSM Brass Thread, Poly Jacket

The 888-5001-306PB Tungsten Carbide Big Gun Long Venturi Nozzle is built for high-performance abrasive blasting where productivity, durability, and consistent results are critical. Its Big Gun long venturi profile accelerates abrasive media more efficiently than straight-bore designs, producing higher particle velocity, wider coverage, and faster surface preparation. The 3/8″ bore delivers a powerful blend of airflow and media volume, making it ideal for demanding industrial work. A tungsten carbide liner ensures exceptional wear resistance and extended service life, while the rugged poly jacket protects against impact and jobsite abuse.
