Nozzle – Tungsten Carbide Long Venturi, 3/16" Bore, 1" Entry, 1-1/4" Brass NPSM Thread, Poly Jacket

Part Number: 501-742
Weight: 1.35 lbs

The 501-742 Tungsten Carbide Long Venturi Nozzle is engineered for high-efficiency abrasive blasting, offering exceptional wear resistance, strong cutting power, and long service life under demanding conditions. Built with a durable tungsten carbide liner, this nozzle provides outstanding performance when used with aggressive abrasives such as steel grit, aluminum oxide, slag, and garnet.

Its 3/16" bore delivers a precise, high-velocity blast pattern ideal for detail-focused industrial cleaning, weld prep, spot blasting, and surface preparation where control and power must be balanced. The long venturi design accelerates abrasive media for increased productivity, improved cleaning speed, and reduced abrasive consumption.

The robust poly jacket protects the carbide liner while offering excellent impact resistance and improved handling. The 1-1/4" Brass NPSM thread ensures compatibility with standard industrial screw-on nozzle holders.

⚠️ IMPORTANT WARNING:
Brass-threaded nozzles can seize when paired with brass nozzle holders.
To prevent galling or permanent thread lock, use aluminum or composite holders.
