Air Lock 3 pc. Plastic
- Fill with water to the fill line with boiled water or sanitizer and insert into a drilled stopper or bung. Clean up and sanitation is easy with the three pieces disassembled. This airlock creates a closed fermentation that allows CO2 to escape from your carboy or bucket but does not allow air back in to contaminate your batch.
- Airlocks enable CO2 to be released during fermentation, but it traps oxygen from entering the fermenter and harming your beer or wine.
- Match it with the 6.5 rubber stopper to fit in the brew pail lid
