Airlocks & Bungs
PriceFrom £0.95
An airlock is a device that creates a water barrier between the outside air (possible contaminents) and the internal fermentation. It allows pressure from fermentation to be released through the water without risk of external exposure, a little like a one way valve. Airlocks are sealed to a fermenter via the bung or grommet which creates an airtight seal.
