Air Lock 3 Piece
The three piece air lock is a great choice for fermenting your beer. Simply 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 air lock creates a closed fermentation that allows CO2 to escape from your carboy or bucket, but does not allow air back in to contaminate your beer. WINE
