If you take of the wand and compare it to Karcher K series fitting with a google search or go into the description of a foamcannon here on AGO. You can compare it to each other and see if it's that karcher K fitting you have. You will need a pipe between the fitting and the foamcannon too. Don't know the English word for it but that plastic tape you put on the threads so it's not going to leak is also great to get and make it function good.
