(Which have criticized some here) tip to seal problem at Hahn:
The seal must be on the outside, not the inside. That's very important, the seal is on the inside can pass through the resulting pressure fluid passing. If the seal on the outside can not happen because the pressure now only on the locknut pushes us all therefore proportional to the pressure becomes denser.
Is incidentally also described as well in the enclosed instructions, so just follow the instructions. And most importantly, all clean (THOROUGHLY). Then you will have a lot of fun with this fermentation tank.
