Features: 1. Compatible with box-type manual sandblasting machines and box-type automatic sandblasting machines. 2. Suitable for sandblasting glass, surface polishing, and machinery parts processing. 3. The blast nozzle accelerates the air and abrasive mixture as it exits the hose. 4. Uses a 35*20*8mm spray gun core. The length of the gun core affects sand production speed, and the inner hole diameter determines sand output volume. 5. Constructed with high-strength, wear-resistant boron carbide. Offers significantly longer service life compared to nozzles made of cemented carbide, tungsten steel, silicon carbide, silicon nitride, alumina, or zirconia. Specifications: Nozzle type: Dry sandblasting machine nozzle Material: Aluminum + boron carbide Color: Black + Silver Boron carbide nozzle dimensions: 35*20*8mm Air inlet outer diameter: 13mm Sand inlet outer diameter: 13mm Operation: 1. Insert the nozzle washer into the contractor-thread nozzle holder and screw in the nozzle by hand until firmly seated against the washer. 2. Once all equipment is properly assembled and tested, point the nozzle at the target surface and press the remote control handle to begin sandblasting. 3. Hold the nozzle 18 to 36 inches from the surface and move it smoothly at a consistent speed to achieve desired results. Slightly overlap each pass. 4. Replace the nozzle when the orifice wears 1/16 inch beyond its original size. Notes: 1. Actual item color may vary slightly from images due to screen differences. Allow 2–3 cm variation due to manual measurement. 2. Minor surface wear is normal. Contact the seller if deep scratches are present. Package Includes: 1 x Air Sandblaster Gun 1 x Boron Carbide Nozzle
