Nozzle – Tungsten Carbide Long Venturi, 3/8" Bore, 1" Entry, 1-1/4" Brass NPSM Thread, Poly Jacket

Part Number: 501-772
Weight: 1.90 lbs

The 501-772 Tungsten Carbide Long Venturi Nozzle is built for high-production blasting environments where maximum durability, abrasive velocity, and coverage efficiency are essential. Tungsten carbide provides outstanding wear resistance, making it one of the most durable nozzle materials for use with aggressive abrasives such as steel grit, aluminum oxide, garnet, and mineral slags.

With its long venturi design, this nozzle accelerates abrasive media to peak velocity, producing a wide, uniform blast pattern ideal for large surface areas and demanding industrial applications. The 3/8" bore supports a strong, consistent abrasive flow—perfect for general-purpose and heavy-duty blasting where both speed and cutting power matter.

A rugged poly jacket protects the tungsten carbide liner from impact damage while keeping the nozzle lighter and easier to handle. The 1-1/4" brass NPSM thread ensures a secure, vibration-resistant fit with compatible nozzle holders.

⚠ WARNING: Do not use brass-threaded nozzles with brass nozzle holders. Threads may seize and become permanently stuck under load and vibration.
