It took me a bit of searching to figure this out (prob shouldn't have) but I figured I would share. I for some reason can't upload all my pics so I just have a pic of the part needed (ill try to get my pics up later). I was looking to have my AG foam cannon quick connect from my pressure washer instead of having to take the handle apart. I had the kranzle attachment and I had to disconnect the sprayer from the handle and then attach the foam cannon. Now it just attaches right to the end like the different sprayer nozzles.

So if you want to quick connect get this 1/4 in. male to 1/4 in. female connector for about $10 ( the part you want is on the left )
