Nozzle – SiAlON Long Venturi, 1/2" Bore, 1" Entry, 50 mm Aluminum Thread, Poly Jacket

Part Number: 104-5430
Weight: 1.10 lbs

The 104-5430 SiAlON Long Venturi Nozzle is a high-performance, lightweight blasting nozzle engineered for operators who demand durability, reduced fatigue, and maximum blasting efficiency. Built with an advanced SiAlON (Silicon Aluminum Oxynitride) liner, this nozzle delivers wear life comparable to tungsten carbide—while weighing only about half as much, making it ideal for long-duration blasting or overhead applications.

Designed with a 1/2" bore, the nozzle produces a powerful, high-velocity abrasive stream capable of rapid material removal, large-surface coverage, and heavy industrial cleaning. The long venturi geometry increases particle acceleration and expands the blast pattern, improving productivity while reducing abrasive consumption.

The 50 mm aluminum threaded connection provides compatibility with metric-style nozzle holders, and the poly jacket adds impact resistance, corrosion protection, and user comfort in demanding blasting environments.

⚠️ WARNING: Nozzles with aluminum threads should NOT be used with aluminum nozzle holders, as they may seize or become inseparable.
