Boron Carbide Short Nozzle 11 mm

Boron Carbide Short Nozzle 11 mm for Abrasive Blasting

This short boron carbide (BC) nozzle with an 11 mm bore is a consumable spare part for dry abrasive blasting systems. It threads directly into a compatible nozzle holder or blast gun assembly. The 11 mm orifice is a common selection for contractors and workshops running medium-to-high media flow rates, balancing cleaning speed with compressed air consumption.

Boron carbide is one of the hardest materials available for blast nozzles, second only to diamond. This makes the nozzle highly resistant to the erosive wear caused by aluminum oxide, garnet, silicon carbide, and other aggressive blast media. A short nozzle configuration is often preferred for tight spaces, touch-up work, or when a wider blast pattern is acceptable.

Key Selection Factors

To ensure this nozzle fits your equipment, verify the following points with your maintenance team or machine manual:

• Thread type and size: The nozzle entry thread must match your nozzle holder. Common types include 3/4" or 1-1/4" straight threads, but variations exist.
• Nozzle length: This is a short pattern nozzle. Confirm the overall length and body diameter fit your blast gun's retaining nut or jacket.
• Jacket material: Boron carbide nozzles are often supplied with a polyurethane, aluminum, or composite jacket. The jacket protects the brittle carbide core from impact damage.
• Media compatibility: The 11 mm bore is suitable for a range of media sizes. Confirm the minimum and maximum grit size your system can pass through this orifice without clogging.

Wear Life and Replacement

All blast nozzles are wear parts. The boron carbide material extends the interval between replacements, reducing downtime and the cost per operating hour. Operators should monitor the orifice diameter regularly. A worn nozzle will show an enlarged, uneven bore, leading to increased air consumption, loss of blast pressure, and reduced cleaning efficiency. A 1/16" increase in orifice size can increase air demand by over 20%, straining the compressor and slowing production.
