Straight-Bore Blast Nozzle Inserts are suitable for most sandblasting guns.

Different materials of Nozzle Insert determine different service life when blasting with aggressive media. The life of boron carbide nozzle insert is 5-10 times of tungsten carbide nozzle insert, 2-3 times of silicon carbide nozzle insert, and 100 times of iron/cast iron nozzle insert.

Estimated Service Life of Nozzles Insert (In hours)

Durable:the nozzle is made of boron carbide, which is the longest lasting material used for blast nozzles.

Cost-effective: boron carbide nozzle inserts are approximately 3 times lower when most aggressive media are used compared with tungsten carbide nozzle.

Easy to replace: the nozzle inserts are easy to replace because of their small size and lightweight.

We Manufacture Different Specifications of Straight-Bore Blast Nozzle Inserts

Product SIZE: Outside Length: 35mm / 45mm / 60mm /80mm *20mm( outer diameter )*Optional( inner diameter) Optional boron carbide tip inner hole diameter: 3mm / 4mm / 5mm / 6mm / 8mm / 10mm/12mm.

The taper and length of the nozzle's inlet and outlet determine the pattern and velocity of the abrasive exiting the nozzle. The longer the length is, the stronger the blasting force.
