Air Lock 3 piece 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 3 pieces disassembled.  This air lock creates a closed fermentation that allows CO2 to escape from your carboy but does not allow air back in to contaminate your beer or wine.  Compatible with all our drilled bungs.
