I currently have and use a Gilmour Foamaster. I was just given a Karcher K series PW. Is it possible for me to purchase the K adapter, and the quick connect to use the Gilmour with the Karcher? I understand that there are other foam lances I could purchase (including one from Karcher) but I was curious if a Gilmour is compatible with my Karcher, or ANY pressure washer at all.
