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

Part Number: 104-6020
Weight: 0.90 lbs

The 104-6020 SiAlON Wide-Entry Long Venturi Nozzle is engineered for operators who require high durability, reduced weight, and maximum blasting efficiency. Featuring an advanced SiAlON (Silicon Aluminum Oxynitride) liner, this nozzle delivers service life comparable to tungsten carbide—yet weighs roughly 50% less, significantly reducing operator fatigue during long or overhead blasting sessions.

The 7/16" bore produces a strong, high-volume blast stream suitable for heavy cleaning, coating removal, rust removal, and industrial surface preparation. Its wide-entry (1-1/4") inlet provides smooth, unrestricted abrasive flow, minimizing pressure loss and increasing media acceleration. The long venturi profile enhances blast velocity and expands the blast pattern for maximum surface coverage and productivity.

The durable poly jacket protects the SiAlON liner from impact, corrosion, and harsh environments while improving handling comfort. The nozzle is equipped with a 50 mm aluminum threaded connection, designed for metric-style nozzle holders.

⚠️ IMPORTANT WARNING:
Do NOT use aluminum-threaded nozzles with aluminum nozzle holders.
Aluminum-on-aluminum threads can gall and become permanently stuck.
Always pair with brass or composite holders to prevent seizing.
