Airlocks are an essential element in fermentation. Airlocks prevent oxygen from getting into a fermenter while at the same time allowing for CO2 to escape. The 3 Piece Airlock is our preferred style of airlocks. We love it because it is easy to take apart and clean.
- This airlock will fit inside any of our bored rubber bungs and corks.
- Be sure to add water to the fill line
