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

Part Number: 502-712
Weight: 1.00 lbs

The 502-712 SiAlON Long Venturi Nozzle is a lightweight, high-durability blasting nozzle designed for operators who need long wear life, reduced fatigue, and consistent performance across demanding abrasive blasting tasks. Constructed with an advanced SiAlON (Silicon Aluminum Oxynitride) liner, this nozzle provides service life comparable to tungsten carbide—yet weighs about 50% less, offering superior handling comfort during extended blasting sessions.

The 3/16" bore delivers a precise, high-velocity blast stream ideal for weld prep, detail blasting, rust removal, and surface preparation in tight or controlled areas. Its long venturi geometry increases abrasive acceleration, improving cleaning speed, surface coverage, and overall blasting efficiency while reducing abrasive consumption.

The durable poly jacket protects the SiAlON liner from impact, corrosion, and harsh jobsite conditions. The 1-1/4" Brass NPSM threaded connection ensures compatibility with standard screw-on nozzle holders commonly used in industrial blasting.

⚠️ IMPORTANT WARNING:
Brass-threaded nozzles used with brass nozzle holders may seize or become permanently stuck.
For safe operation, pair with aluminum or composite holders to prevent thread galling.
