Cant find the right nozzle/wand 4my PresWash

a link would be nice for a universal nozzle or wand? not sure which i need and what not? it came with a rotary nozzle which i think is too aggressive and not cool. I want one that sprays a straight pattern, like at the car wash. I think i want a 40degree tip/nozzle. its a karcher 3.86
thanks

 

something like this setup

 

Not sure if this is what you're looking for, but I actually messaged the owner of that video (for info on his foam cannon) and he mentioned the website Karcher Pressure Washers, Karcher Parts, Karcher Accessories, Karcher Power Washers and Pressure Washers

Maybe this is what you're looking for?
