MTM Hydro PF22.2 Foam Cannon

MTM Hydro's Italian-made PF22.2 foam cannon is the new standard in the foam industry and bills itself as the most reliable foam cannon in the industry.

With its new upright bottle, you no longer have to worry about spills and spills.

Whether you're foaming in your car on the weekends or you're a pro at cleaning the foaming pigsty for hours on end, this tool will save you time and money.

Simply attach the foam cannon to your pressure washer using one of the included fittings, fill with the desired ratio of chemical into the calibrated stand bottle and you're up and running.


A specific 1/4" male plug may be required to attach the QC plug to the end of some residential pressure washer setups. MTM Hydro 1/4" plugs are standard for industrial use, but many pressure washers Residential such as Generac, Greenworks, Ryobi, AR Blue Clean, etc... have some models where the coupler will not receive an MTM plug.

Not all of these brands are affected, only certain models. If you look closely, the chamfer on the end of an MTM plug as well as the neck is 1.5mm shorter than some couplers may allow.

Contents of the PF22 Foam Cannon Kit:

  • Nickel Plated Italian Brass - One Piece Foam Cannon Body
  • New 32oz Italian Calibrated Gray Bottle
  • 1/4" x 9" tubing for drawing chemicals
  • 3.5 (1.25mm) orifice installed in aerator body
  • 3.0 Orifice (1.1mm) included with kit
  • Set of fittings (2 pieces) containing a 1/4 "M22 adapter and a 1/4" plug in QC plated steel
  • Manual with maintenance instructions and exploded view


  • Min. 1100psi - Max. 5000psi
  • Min. 1.4 gpm - Max. 5.3 gpm
  • Max. 140°F


The full spectrum of ratings is not supported by the 3.5 or 3.0 ports included with this kit.

Other orifices may be required for higher flow machines that have lower PSI - Example: 2000 PSI with 3.5 GPM requires a 5.0 orifice.

For larger orifices, you'll know it's not working because you'll experience the foam cannon starting and stopping as your unloader slides in and out of the bypass.

You will also get watery foam as the 3.5 orifice size is significantly smaller than the 5.0 needed for your machine. MTM foam cannons will not work with flow sensing unloaders because you will get the same results as listed for an undersized orifice.

See below for additional orifice sizes and replacement items available for purchase.
