Foam Cannon Orifice
Most people don’t realize the orifice size inside the cannon is what controls how your pressure washer performs. Too small, you choke the machine. Too big, you lose foam quality. These inserts fix that.
What This Is
Precision orifice inserts designed to tune your foam cannon based on your pressure washer’s output.
Available sizes:
- 1.1mm
- 1.25mm
- 1.5mm
Your pressure washer isn’t universal. Flow rate (GPM) and pressure (PSI) matter.
Here’s what happens:
- Too small (like 1.1mm on a higher flow unit)
- Strangles water flow
- Spikes pressure
- Can stress the pump
- Too large (like 1.5mm on a low flow unit)
- Weak foam
- Watery output
- Feels like your cannon is broken
This is why people think their foam cannon sucks. It’s not the cannon. It’s the insert.
