1.1mm and 1.25mm nozzle screw jet

There are two kinds of nozzle scrw jet sizes, 1.25mm and 1.1mm. Normally, each MJJC foam lance is with 1.25mm nozzle screw jet already. Generally, you may need the 1.25mm one for replacement if the previous one is broken for some reason. However, if your pressure washer is with too small pressure or very small output flow rate(usually for lower than 110Bar pressure), you need to replace the 1.25mm nozzle jet with 1.1mm one on your snow foam lance to produce thicker foam to better washing your vehicle. For example, in USA, as the electricity is just 110v voltage, so most Elecrical power washers are very compact and small pressure, for those pressure washers, most people need this 1.1mm nozzle screw to make thick foam.

However, every pressure washer has its unique specifications. for example, some small pressure washers have low pressure, but a big output flow rate. So, sometimes, even if your pressure washer is 110Bar pressure, you still don't need to replace the nozzle screw jet.

As long as your foam lance (foam cannon) works fine with your pressure washer, then don't bother to replace the nozzle screw.

here are some FAQ about 1.1mm nozzle screw jet:

 

1. Why do the 1.1mm and 1.25mm nozzles look the same?

The 1.1mm and 1.25mm nozzles look exactly same, they are just with different holes 1.1mm and 1.25mm, the holes are very small, so we can't recognize the difference by eyes.

2. Why can't my foam lance(foam cannon) create thick foam like others?

the foaming performance depends on not only the foam lance, but also the pressure and output rate of your power washer, as well as your car wash shampoo (soap). foam lance would make great foam with concentrated shampoo(soap), but most brands of shampoo(soap) is not concentrated type, even if they are big brands.

3. Does this spare nozzle screw work with other brands of foam lance(foam cannon)?

No, this nozzle screw is specially designed for MJJC foam lance only.
