Can I blast without a nozzle?
If you need to cover a wide swath of material or douse a part surface in abrasive, it seems logical to remove the nozzle and blast away. But the abrasive hose isn’t like a garden hose. The nozzle on a Comco blaster does more than focus and funnel the abrasive stream, it helps keep abrasive moving at a consistent and regulated pace throughout the machine.
Removing the nozzle increases the velocity of the abrasive stream inside the blaster. The resulting surge is hard to control both inside and outside of the blaster. Abrasive moving at high velocities inside the blaster speeds up wear and tear on the handpiece threads, the abrasive hose, and the PowderGate or pinch valve.
Use a larger tank orifice and potentially a larger nozzle. Consult our Sales Team to get the right configuration. Call 1-800-796-6626 (outside the US, call 1-818-841-5500) or use the Contact Us form below to start the conversation.
Should the nozzle and tank orifice be the same size?
The opening at that bottom of the abrasive tank should always be smaller than the nozzle. Abrasive can’t do its work when the stream is that crowded. If you need more abrasive in the stream, use a larger tank orifice, and if needed, a larger nozzle.

What types of nozzles are available?
Our nozzles come in an array of shapes and sizes for a wide range of applications.
- The straight, round style nozzle with openings ranging from 0.015″ to 0.125″ meets most application requirements.
- Rectangular nozzles are available for applications that require a wide sweep or fan of abrasive.
- Comco’s Hi/Performance nozzles outlast our standard nozzles and deliver an accelerated abrasive flow with a tighter focus, resulting in less overspray.
- Custom nozzles
