I decided to make a less costly, simpler solution for those that want to upgrade their pressure washer. This is a modular system that will be upgradeable in the future. You could easily add the higher-end foam cannon or Mosmatic wand if you'd like. I am putting together the following:
MTM SG-28 Spray gun
All MTM Stainless Steel Quick Disconnects
MTM Brass M22 to 3/8" Adapter to connect to your pressure washer hose outlet
MTM 4.0 Orifice 40 Degree Spray Nozzle
Original MTM Foam Cannon w/ MTM Stainless Plug
***Option to Add MTM PF22 Upgraded Foam Cannon***
This will be shipped with all quick disconnects teflon taped and installed. The only thing you will need to do is connect the M22 adapter to your pressure washer hose outlet.
*This works with most pressure washer hoses, but you may need to check the outlet size to get the proper adapter.
