Dip Tube suggestion12/06/2016 ByJoseph Keogh The first time I installed the dip tube in my fermentor and filled it, the fermentor leaked at the fitting and I had to transfer my wort to a carboy. I was going to return it but thyoughyt about and made a rubber gasket to go between the plate and the fermentor and no more leaks. A sanitary gasket, if there is such a thing would be better than the rubber one i made. I think you should offer a gasket for those plates.
