Tungsten Carbide Venturi Nozzle 5.5 mm

Venturi Nozzle Design for Abrasive Blasting

A venturi nozzle features a converging inlet, a narrow throat, and a diverging outlet. This internal shape converts the pressure energy of compressed air into kinetic energy, accelerating abrasive particles to exit speeds that can exceed 100 m/s. The result is a focused, high-velocity blast pattern that strips rust, mill scale, and old coatings faster than a straight-bore nozzle of the same air consumption.

The 5.5 mm bore diameter is a mid-range size. It offers a practical balance: enough impact for structural steel and concrete surface prep, without the excessive air demand of larger orifices. If your compressor output is limited, or you need finer control on thinner substrates, this bore size is worth evaluating.

Tungsten Carbide Material and Wear Life

The nozzle body is made from cemented tungsten carbide, a material chosen for its extreme hardness and resistance to erosion from high-speed abrasive particles. In dry blasting with mineral abrasives like garnet or aluminum oxide, a TC nozzle typically outlasts a ceramic nozzle by a factor of 3 to 5, and far exceeds the life of a cast iron nozzle.

Actual wear life depends on several factors: abrasive type and mesh size, blast pressure, operator technique, and whether the nozzle is run continuously or intermittently. Harder, sharper abrasives such as aluminum oxide will wear the bore faster than rounded media. Regular inspection of the bore diameter and exit profile helps you schedule replacement before the blast pattern degrades and air consumption rises.

Compatibility and Replacement

This nozzle is a spare part for sand blasting machines that accept a venturi-style tungsten carbide nozzle. It is not a universal fit. Before ordering, confirm:

• Thread type and size – The nozzle entry thread must match your holder or coupling.
• Overall length and body diameter – Must fit within your blast hose whip or nozzle holder assembly.
• Washer or gasket seat – Some holders use a flat seat; others require a cone or O-ring seal.

If you are unsure about compatibility, contact SPA2Z with your machine make, model, and existing nozzle dimensions. We will help you verify fitment before you buy.
