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

Part Number: 104-5940
Weight: 1.00 lbs

The 104-5940 SiAlON Long Venturi Nozzle is engineered for high-performance abrasive blasting, offering a premium combination of long wear life, reduced weight, and exceptional blasting efficiency. Built with an advanced SiAlON (Silicon Aluminum Oxynitride) liner, this nozzle provides durability comparable to tungsten carbide—yet weighs about 50% less, significantly reducing operator fatigue during extended blasting sessions or overhead work.

Designed with a 1/2" bore, this nozzle produces a powerful, high-volume blast stream ideal for heavy cleaning, coating removal, structural steel preparation, and high-production blasting. The long venturi profile accelerates abrasive particles to maximize cleaning speed, surface coverage, and efficiency while reducing abrasive consumption.

The 1-1/4" wide-entry inlet promotes smooth abrasive flow with minimal pressure drop, while the 50 mm threaded connection ensures compatibility with metric-style nozzle holders. The durable all-poly jacket provides impact protection, corrosion resistance, and comfortable handling.
