Boron Carbide Stick Up Nozzle for Sandblasting Guns

A Boron Carbide Stick Up Nozzle, also known as a slip-in nozzle, push-in blast nozzle, or plug-in nozzle, is a high-performance abrasive blasting nozzle designed for industrial surface preparation applications.

Unlike conventional threaded blast nozzles, this sandblasting gun nozzle can be directly inserted into a blast gun or blast hose without requiring a nozzle holder. Its compact structure and lightweight design make it an ideal handheld blast nozzle for portable blasting equipment and confined-space operations.

Available in both straight bore blast nozzle and Venturi configurations, stick up nozzles provide excellent wear resistance, high blasting efficiency, and long service life.

What Is a Stick Up Nozzle?

A stick up nozzle is a type of blast gun nozzle featuring a cylindrical body that slides directly into a blast hose or sandblasting gun.

The nozzle is secured by friction and an anti-slip aluminum sleeve, allowing quick installation and replacement. Because of its compact dimensions, it is often used as a small sandblasting nozzle in portable blasting systems.

Common names used by global buyers include:

• Stick Up Nozzle

• Slip-in Nozzle

• Push-in Blast Nozzle

• Plug-in Nozzle

• Blast Hose Nozzle

• Sandblast Gun Nozzle

Key Features

Straight Bore and Venturi Designs

Two internal bore designs are available:

Straight Bore Blast Nozzle

Provides a concentrated abrasive stream with precise impact control, making it suitable for detail cleaning, weld preparation, and localized surface treatment.

Venturi Blast Nozzle

Accelerates airflow and abrasive velocity, delivering up to 40% higher blasting productivity while reducing abrasive consumption.

Advantages of Boron Carbide Blast Nozzles

Compared with tungsten carbide and ceramic nozzles, boron carbide blast nozzles offer significantly longer service life and lower operating costs.

Superior Wear Resistance

• 3–5 times longer life than tungsten carbide nozzles

• 20–50 times longer life than steel nozzles

• Excellent resistance to abrasive erosion

Corrosion Resistance

Suitable for:

• Acid environments

• Alkali solutions

• Salt spray exposure

• Chemical processing applications

Lightweight Design

With a density of approximately 2.5 g/cm³, boron carbide nozzles are around 40% lighter than tungsten carbide alternatives, making them ideal handheld blast nozzles for extended operation.

High Precision Blasting

The smooth internal bore minimizes turbulence and pressure loss, ensuring stable abrasive flow and accurate blasting performance.

FAQ 

What is the difference between a stick up nozzle and a threaded blast nozzle?

A stick up nozzle is a slip-in nozzle that installs directly into a blast gun or hose without threads, making replacement faster and easier.

Are boron carbide blast nozzles better than tungsten carbide nozzles?

Yes. Boron carbide blast nozzles typically last 3–5 times longer than tungsten carbide nozzles when used with abrasive media.

What industries use stick up nozzles?

These sandblasting gun nozzles are commonly used in shipyards, steel fabrication, construction equipment manufacturing, foundries, and industrial surface preparation.
