Nozzle – SiAlON Wide-Entry Long Venturi, 1/2" Bore, 1-1/4" Entry, 50 mm Aluminum Thread, Poly Jacket

Part Number: 104-6030
Weight: 1.00 lbs

The 104-6030 SiAlON Wide-Entry Long Venturi Nozzle is engineered for high-performance abrasive blasting, combining exceptional durability with lightweight handling for improved operator comfort. Built with an advanced SiAlON (Silicon Aluminum Oxynitride) liner, this nozzle provides wear resistance comparable to tungsten carbide while weighing about 50% less, making it an ideal choice for long-duration blasting, overhead work, and repetitive industrial applications.

The wide-entry 1-1/4" inlet ensures smooth, unrestricted abrasive flow, minimizing pressure loss and maximizing blasting efficiency. The long venturi design increases abrasive velocity and expands the blast pattern for faster cleaning rates, enhanced coverage, and improved abrasive economy. The 1/2" bore offers excellent cutting power, making this nozzle suitable for heavy-duty surface preparation and high-production blasting environments.

The durable poly jacket enhances handling comfort while providing impact and corrosion resistance. The 50 mm aluminum threaded connection allows secure attachment to compatible metric-style nozzle holders.

⚠️ IMPORTANT WARNING:
Do NOT use aluminum-threaded nozzles with aluminum nozzle holders.
Aluminum-on-aluminum threading can cause galling, leading to threads seizing or becoming permanently inseparable.
Use brass or composite holders for safe operation.
