Made from HDPE this plastic tap will screw into most standard fermenters as it uses a very common 3/4inch thread. These also fit the 20L plastic cubes. This is a common plastic tap used on many fermenters. The tap can be taken apart for cleaning if you put a piece of wood dowel in the thread end and bang it the tap will come apart. Taps can sometime harbour wild yeast or bacteria. To be absolutely sure you have sanitised the tap you can boil this tap in hot water.
