This is the connection a lot of you will need to use a foam cannon with your applicable Ryobi, GreenWorks, AR Blue, SunJoe & Karcher OE spray gun (Usually the ones with removable stainless wands). It takes a M22 to adapts it to a 1/4" connection. This allows you to put the foam cannon on the shorter part of the gun vs having it all the way out on the end of the wand. It makes it easier to handle and looks less goofy.

Not Included:

M22 14mm Is Compatible with the following pressure washers (Active 2.0, Kranzle, AR Blue Pro line, Karcher, Ryobi, Green Works)
