1.1mm orifice is suggested to work on most under-110Bar pressure washers (eg. Karcher K1 series).
1.1 mm Orifice for Low Pressure Washers allows you to achieve a higher flow compared to the standard orifice in your Foam Cannon! If your pressure washer is struggling with your Foam Lance/Cannon, or you are simply looking to take your foam to the next level, this 1.1 MM Orifice is a great option!
