Hi, I have owned Karcher K2 pressure washers and have a few accessories (snow foam lance and a better quality hose).
The main unit started leaking (again) so bought a new one today but I have noticed they have changed the fitting where the lance hose connects to the main unit which means I can't connect my better quality rubber hose.
I think there is an adaptor I can buy but not sure on sizes.
The new Quick Connect lance hose is on the left and my traditional screw thread is on the right.

I think this is the one but any advice welcome.
