Tungsten carbide Venturi blast nozzle – rugged for large surfaces
The Venturi bore with converging entry and diverging exit creates a wide blast pattern and greatly increases abrasive velocity – ideal for blasting large surfaces. The tungsten carbide insert in an aluminium jacket gives this general purpose nozzle durability and toughness; it is supplied with a rubber gasket.
A larger orifice produces a greater blast coverage area but needs more air capacity from the compressor; a smaller orifice gives a narrower pattern and uses less air. As a general rule, replace the nozzle when the orifice has worn by one nozzle size – easy to check with the Elcometer 103 Blast Nozzle Gauge.
At a glance
- Wide blast pattern: Venturi bore for high productivity
- Rugged: aluminium jacket with a very high level of protection against impact damage
- Economical: tungsten carbide is impact resistant and relatively inexpensive – good for mineral, glass and slag abrasives
- 2" contractor thread: the industry standard at 4½ TPI – greatly reduces cross threading, easy to attach, safer at high pressure
- With rubber gasket: for nylon nozzle holders; aluminium holders come with their own gasket

Which bore lining is right?
- Tungsten carbide (TC): relatively inexpensive and impact resistant – ideal where rough handling cannot be avoided and with mineral, glass or coal slag abrasives
- Silicon carbide (SC): impact resistant and durable like tungsten carbide, but approximately one third of the weight – ideal for long blasting periods
- Silicon nitride (SN): outstanding wear resistance and up to 50 % lighter than other nozzles of the same size – reduces operator fatigue
- Boron carbide (BC): extremely hard wearing, up to ten times the longevity of tungsten carbide – ideal for aggressive abrasives
