Cap for a demijohn 138mm

Cap for demoijohn with a wide neck (138mm) is used to seal tightly during fermentation.

Before use, the hoods should be washed thoroughly with warm water and washing-up liquid, and then dried thoroughly. This is to remove the layer of silicone left over from the production stage that may cause the rubber hoods to slip off during fermentation.

The hoods are very stretchy, which makes it possible to use them on various vessels, they can serve as a tight closure of the balloon or, after cutting the plug, as a stopper with an opening for a fermentation tube.
