Powerwasher Universal Underbody & Gutter Cleaning Wand (Electric)

This will not fit with a Campbell Hausfeld.

I'm sorry, but we don't carry Task Force pressure washers- I don't know if an adaptor for that brand is included.

You may want to give the folks at Powerwasher a call, toll free, at 877-362-4271 to see if they know.

You could also try matching up the connector profile from your unit to the ones in our picture- as you can see the shape and position of the "ears" on each adaptor is very different, and they must match exactly so they don't leak.

Unfortunately it will not. Your Stanley unit uses manufacture specific connections and I do not have any accessories compatible with your unit. I would recommend calling the manufacture to see where accessories can be purchased. Their number is 800-393-0668

Yes, this PowerWasher spray kit does come with a Karcher bayonet adapter included. This kit will be compatible with your Karcher K5.740 model pressure washer.
