⭐️Balloon stopper diameter 51/43 mm rubber⭐️

✨ The rubber conical stopper is designed for mounting the fermentation airlock on bottles with necks ranging from 45 to 50 mm in diameter.

✨ It has a hole that allows the attachment of glass and plastic fermentation tubes and gaskets.

✍️ It is recommended to wash the cork thoroughly before use with warm water and dishwashing liquid, then dry it thoroughly. This process removes the layer of silicone remaining after production, which can prevent the cork from slipping out of the bottle during fermentation or from slipping, which is typical for rubber cork.
