This airlock (LK210) is the perfect choice for containers up to 25 gallons in volume. It is also a good choice for when rapid fermentation is expected with smaller batches. This specific airlock will work for wine or beer. Just fill approximately half way with water. The water acts as a environmental barrier to keep bugs and other unwanted elements out of your batch, while still allowing gasses to escape the fermentation.

I've found these simple airlocks work the best with co2 fermentation in my 6 gallon carboys along with using the #7 rubber cap. Makes fermentation pretty simple."excellent piece of equipment" Review by Ken (Posted on 11/5/12)
