This 3-piece airlock is the best choice for relieving gasses from your fermentation, as it comes apart extremely easily for cleaning if a blow-off occurs. All you have to do is fill to the line with boiled or sanitary water, insert into a drilled stopper or bung, and it creates a closed fermenting system that allows Co2 to escape, while not allowing air back into the container to contaminate your product.
