Product Details
A Sandblast Nozzle is a precision-engineered tool designed to accelerate a mixture of compressed air and abrasive media (like sand, steel grit, or glass beads) to high velocities. It is the final component of a sandblasting system and determines the velocity, pattern, and efficiency of the cleaning or etching process.
🔬 Internal Geometry: Straight vs. VenturiThe shape of the internal bore dictates how the abrasive hits the surface:1
-
Straight Bore: Used for small-scale jobs like cabinet blasting or spot cleaning. It creates a tight, concentrated blast pattern but loses velocity quickly.2
-
Venturi Bore: Features a tapered entry that constricts the air and then expands it.3 This creates a "vacuum effect" that accelerates the abrasive particles to much higher speeds (up to $720$ km/h), creating a larger, more uniform blast pattern.
-
Double Venturi: Features two venturis in a row with atmospheric air holes, which increases the size of the "hot spot" (the most effective part of the blast pattern) by up to 4$35%$.5
Since abrasive media "sandblasts" the nozzle from the inside, the material choice determines the nozzle's lifespan:
| Material | Durability (Est. Hours) | Best Use Case |
| Ceramic | $1$ – $2$ hours | Occasional DIY use, light etching. |
| Tungsten Carbide | $300$ – $500$ hours | Standard industrial blasting; high impact resistance. |
| Silicon Carbide | $500$ – $800$ hours | Lightweight; reduces operator fatigue during long shifts. |
| Boron Carbide | $1,000$ – $1,500$ hours | Best for aggressive media like Aluminum Oxide or Silicon Carbide. |
-
Bore Size: Usually measured in $1/16"$ increments (e.g., a #4 nozzle is $1/4"$). The bore size must be matched to your Air Compressor's CFM (Cubic Feet per Minute) output.6
-
Entry Throat: Common sizes are $25mm$ ($1"$) or $32mm$ ($1-1/4"$).
-
Jacket Material: Typically encased in Aluminum, Polyurethane, or Brass to protect the brittle carbide liner from external impact.7
-
Threads: Most industrial nozzles use a $50mm$ Contractor Thread or a $1-1/4"$ NPSM thread for secure attachment to the nozzle holder.
