This plastic twin bubble air lock (aka “S” lock) is an essential tool for allowing fermentation gases to escape from your fermentation vessel while also preventing bugs and bacteria from getting into your brew. Fill to approximately half way to the fill line with water.

The twin bubble air lock is harder to disassemble and clean, but it is easier to monitor bubble activity.
