The adapter connects with me a pull-out kitchen faucet with a hose for Kärcher, so I can radiate my balcony / sometimes just the flowers pour. The adapter is suitable for taps with M 22 x 1 indoor and M 24 x 1 male thread with a relatively small flange - possibly you have even a "Adapter for Faucet extension" at Amazon or at the hardware store (there are in all possible diameters and lengths - so that should be a connection almost always succeed) to buy.
The construction is otherwise really great when you no longer need to hose it disappears together with adapter in the closet. The processing is gardenatypisch very good, nothing drips or spills and so remains in comparison to the apartment Gieskannenschleppen dry :-)! Strong buy recommendation!
