But I have found that this adapter does not fit in any Hahn. It is greatly to the installation depth of the thread in the faucet. The Gadena thread which is screwed into the valve, has a relatively short thread. Thus, if the thread of the tap very low, for example due to the design of the water outlet, the Gardena coupling does not close properly (the gray part with organgen slide). Thus, it is leaking and water splashes out on the side.
At first it was not tap. Not until the second I got it with fine adjustment. The Gardena adapter may be doing just exactly as much pure screwed he is close and far enough comes out to connect the clutch. So not until you feel a resistance.
The principle is good, but a longer thread would be even better.
