In which cases do you need copper paste?

Only for the Titanium Stahlbus Bleeder Valve it is necessary to apply copper paste to the thread of the bottom and upper part so that it cannot jam at the time of being inserted. The valves are already delivered with copper paste on their threads. This is not imperative for the steel valve; however, the paste does not harm either. So, if you feel better you may handle the steel valves the same way.
