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

Part Number: 1348-555
Category: Sandblasting & Abrasive Nozzles
Type: Tungsten Carbide Long Venturi Nozzle – 5/16″ Bore, 1-1/4″ Entry, 1-1/4″ NPSM Brass Thread, Poly Jacket

The 1348-555 Tungsten Carbide Long Venturi Nozzle is engineered for maximum blasting efficiency and long service life in demanding industrial environments. Its long venturi profile accelerates abrasive media more effectively than straight-bore designs, delivering higher impact velocity, faster cleaning rates, and more consistent surface coverage. Built with a tungsten carbide liner, this nozzle offers exceptional wear resistance and maintains bore accuracy far longer than ceramic alternatives. The durable poly jacket provides added protection while keeping weight manageable for extended use. Featuring a 1-1/4″ entry and 1-1/4″ NPSM brass threads, this nozzle fits standard professional blast systems and holders.
