Nozzle – SiAlON Long Venturi, 1/4" Bore, 1" Entry, 1-1/4" Brass NPSM Thread, Poly Jacket

Part Number: 502-722
Weight: 1.00 lbs

The 502-722 SiAlON Long Venturi Nozzle delivers exceptional blasting performance with a lightweight, durable design ideal for extended operation. Built with an advanced SiAlON (Silicon Aluminum Oxynitride) liner, this nozzle provides service life comparable to tungsten carbide—while weighing about 50% less, dramatically reducing operator fatigue during long shifts or overhead blasting.

The 1/4" bore produces a high-velocity, precision blast stream suited for detailed surface preparation, coating removal, metal cleaning, and small-area industrial blasting. Its long venturi design increases abrasive acceleration for faster cleaning rates, improved coverage, and more efficient abrasive usage.

The poly jacket offers impact resistance, corrosion protection, and improved handling comfort. A 1-1/4" Brass NPSM threaded connection ensures secure attachment to standard screw-on nozzle holders used throughout the abrasive blasting industry.

⚠️ IMPORTANT WARNING:
Brass-threaded nozzles may seize when used with brass nozzle holders.
To avoid permanent thread galling, pair with aluminum or composite holders.
