Nozzle – SiAlON Long Venturi, 7/16" Bore, 1-1/4" Entry, 50 mm Thread, All-Poly Jacket

Part Number: 104-5930
Weight: 1.10 lbs

The 104-5930 SiAlON Long Venturi Nozzle is a high-performance, lightweight blasting nozzle designed for contractors and operators needing maximum efficiency, reduced fatigue, and long wear life. Constructed with an advanced SiAlON (Silicon Aluminum Oxynitride) liner, this nozzle provides durability comparable to tungsten carbide—while weighing approximately 50% less, making it ideal for long-duration blasting or overhead work.

With a 7/16" bore, this nozzle delivers a strong, high-velocity blast stream capable of fast material removal, large-surface cleaning, and industrial maintenance tasks. The long venturi design increases abrasive velocity and expands the blast pattern, improving productivity, surface coverage, and abrasive economy.

The 1-1/4" wide-entry inlet supports smooth, unrestricted abrasive flow, reducing pressure loss, while the 50 mm threaded connection ensures compatibility with metric-style nozzle holders. The all-poly jacket provides excellent corrosion resistance, impact protection, and comfortable handling in harsh blasting environments.
