Foam Cannon Adapter Connector with a 1/4" Brass Male Fitting for karcher k Series K2/K3/K4/K5/K6/K7 Pressure Washer Accessories

This little adapter is a game changer, i love it, now i can use my foam cannon with my karcher machine, i had to red loctite the threads tho cuz when it was fully tightened it wouldn't line up straight with the gun so i red loctite it straight and let it dry now its great,,,,

Does the trick. I use with my Karcher K5 to connect a Foam Cannon.

this works perfectly except for the rubber o-ring that attaches to the pressure washer hose. that o-ring gets squashed and leaks and/or blows out completely. take it off and replace with teflon tape. simple fix that took ~5mins and it's worked flawlessly ever since.

great product

The quality of this item is excellent and it is great to find adaptors that allow you to move away from Kärcher proprietary designs. Unfortunately, as noted by others, this is NOT a 1/4” NPT male thread as advertised but rather a metric M14 Fine male thread. (Note the longer thread that fits into the black Kärcher adaptor is 1/4” NPT.) So if this adaptor works for you depends on whether your foam cannon (or some other item) uses metric adaptors or treads. Things like the MTM PF22 and Torq use 1/4” NPT (or, in many cases, a 1/4” quick disconnect). What I did is get a 1/4” male to 1/4” male connector and adapted the black piece you see in the picture to a separate 1/4” quick disconnect (the Forney 75127 unit available on Amazon).

The thread does not fit the PF22 MTM canon. The thread is bigger than what is should be.

This adapter worked on my pressure washer, but the brass fitting supplied didn't work. I had to buy a 1/4" brass nipple to attach it to the foam canon

Used this attachment between my Karcher and the foam cannon. Works as advertised. Seals well and attach to to washer firmly.
