Rubber Carboy Cap — Small

A flexible natural rubber cap that fits over the outside of a carboy neck rather than inside it, providing a secure and airtight seal. Features a central hole for fitting an airlock. Note: the small cap is a very tight fit and is not recommended for most of our carboys or demijohns — see the medium or large cap if you're unsure.
