As a substitute for a Y-distributor without shut-off valves I bought this product. The reviews for this distribution in not chromed finish, I can only wholeheartedly agree. The article is impeccable, the supplied gasket for connection to the stopcock is scrap. When screwing it has totally twisted, there was of course no tightness reach. So I have the old seal mounted and everything was dicht.Meiner view the supplied gasket is simply too soft and therefore not inherently stable enough to tight can. As this is a "penny" article is (if you can not use an old gasket), full points.
