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

Part Number: 104-5390
Weight: 0.75 lbs

The 104-5390 SiAlON Long Venturi Nozzle is engineered for operators who need a durable, lightweight, and high-performance blasting solution. SiAlON (Silicon Aluminum Oxynitride) delivers service life comparable to tungsten carbide while weighing about 50% less, dramatically reducing operator fatigue during long blasting shifts. This makes the 104-5390 nozzle an exceptional choice for contractors who prioritize both durability and comfort.

The long venturi design accelerates abrasive media to maximum velocity, producing a fast, uniform blast pattern that boosts productivity and reduces abrasive consumption. With its 1/4" precision bore, this nozzle provides a tight, high-speed stream ideal for detailed blasting, spot cleaning, and controlled surface preparation.

A rugged poly jacket protects the SiAlON liner from impact and wear, while the 50 mm aluminum thread ensures compatibility with industrial nozzle holders using this thread style.

⚠ WARNING: Nozzles with aluminum threads should not be used with aluminum nozzle holders. The metals can seize and become inseparable under vibration and load.
