SiAION Big Gun Long Venturi Nozzle – 1/2″ Bore, 1-1/4″ Entry, 1-1/4″ NPSM Thread, Aluminum Jacket

Part Number: 888-5000-308PB
Category: Sandblasting & Abrasive Nozzles
Type: SiAION Big Gun Long Venturi Nozzle – 1/2″ Bore, 1-1/4″ Entry, 1-1/4″ NPSM Thread, Aluminum Jacket

The 888-5000-308PB SiAION Big Gun Long Venturi Nozzle is a high-output, lightweight blasting nozzle engineered for large-scale abrasive applications where maximum productivity, durability, and operator comfort are essential. Featuring a wide 1/2″ bore and a long venturi profile, this nozzle accelerates abrasive media to higher exit velocities, delivering rapid surface coverage and aggressive material removal compared to straight-bore designs. Constructed from advanced SiAION material and protected by an aluminum jacket, it provides service life and wear resistance comparable to tungsten carbide—at roughly half the weight. This makes it an ideal choice for operators working extended shifts who need top-tier performance without added fatigue. Designed with a 1-1/4″ NPSM thread and 1-1/4″ entry, it fits Big Gun-style holders commonly used in industrial and production blasting environments.

Important Notes

• Do not use aluminum-thread nozzles with aluminum nozzle holders—they may become stuck or inseparable

• SiAION Big Gun nozzles are not recommended for use with steel grit

• For steel grit applications, use the Tungsten Carbide version: PN 888-5001-308PB

• Verify bore size (1/2″), entry (1-1/4″), and thread (1-1/4″ NPSM) before ordering

• Service life varies based on abrasive type, air pressure, and duty cycle
