Nozzle – SiAlON Long Venturi, 5/16" Bore, 1" Entry, 1-1/4" Brass NPSM Thread, Poly Jacket

Part Number: 502-732
Weight: 1.00 lbs

The 502-732 SiAlON Long Venturi Nozzle is engineered for high-performance abrasive blasting, offering a premium combination of durability, lightweight handling, and blasting efficiency. Built with an advanced SiAlON (Silicon Aluminum Oxynitride) liner, this nozzle delivers wear resistance comparable to tungsten carbide while weighing about 50% less, making it an excellent choice for operators working long shifts or performing overhead blasting.

The 5/16" bore provides a balanced, high-velocity blast stream with excellent precision and cleaning power. Its long venturi profile accelerates abrasive media to higher exit velocities, increasing productivity, improving surface coverage, and reducing abrasive consumption. The poly protective jacket adds impact resistance, corrosion protection, and comfortable handling in industrial environments.

Equipped with a 1-1/4" Brass NPSM threaded connection, this nozzle fits industry-standard screw-on holders used across pressure blasting systems.

⚠️ IMPORTANT WARNING:
Brass threaded nozzles can seize or become inseparable when used with brass nozzle holders.
For best results, pair with aluminum or composite holders.
