The MTM Hydro Foam Gun works with and gas or electric pressure washer from 500 – 4,000 PSI. Never exceed 4,000 PSI with any foam cannon. Minimum gallon per minute (GPM) rating is 1.8; we suggest using a 2.0 GPM rated pressure washer, do not exceed 5.3 GPM. This unit ships with a 1.25 mm orifice installed, but the kit also contains a 1.1mm orifice for low volume machines.
• 1.1 mm orifice – ideal for low volume (1.4 to 2.4 GPM) pressure washers
• 1.25 mm orifice (installed from factory) – ideal for 2.0 to 5.3 GPM pressure washers
Kit also contains the following items:
• M407 Spray Gun
• ¼” plug coupler for connecting to M407 Spray Gun, or existing pressure washer wand
• Brass Quick Connect coupler for the M407 Spray Gun
• M22 screw coupler for connecting the M407 Spray Gun to the pressure washer hose. Note: Greenworks, AR, Ryobi, and/or Sunjoe pressure washers may require an M22 15 mm adapter to connect their high pressure hose to the M407 Spray Gun.
