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

Part Number: 501-752
Weight: 1.60 lbs

The 501-752 Tungsten Carbide Long Venturi Nozzle is built for high-efficiency abrasive blasting, offering long wear life, high-velocity performance, and exceptional durability in industrial environments. Featuring a rugged tungsten carbide liner, this nozzle withstands aggressive media—including steel grit, aluminum oxide, slag, and garnet—making it an excellent choice for demanding, high-production blasting operations.

The 1/4" bore delivers a fast, concentrated blast stream ideal for precision cleaning, coating removal, metal prep, and detailed surface work. With its long venturi geometry, the nozzle accelerates abrasive particles to higher velocities, improving cleaning speed, coverage area, and overall efficiency.

The lightweight poly jacket protects the carbide liner while providing improved impact resistance and comfortable handling. The 1-1/4" Brass NPSM thread ensures strong compatibility with industry-standard screw-on nozzle holders and resists corrosion in harsh blasting conditions.

⚠️ IMPORTANT WARNING:
Brass threaded nozzles can seize when used with brass nozzle holders.
To avoid galling or thread lock, pair this nozzle with aluminum or composite holders only.
