Twin Bubble Airlock S Type Airlock One-way exhaust water seal valve with Silicon Grommet Beer Wine Making
The advantage of this type of airlock is that they have a smaller chamber so you can more closely observe the CO2 rising and therefore the rate of fermentation. They are also handy when you are cooling a beer as there is less chance of sucking airlock water back into the fermentation. They cannot be cleaned manually if they get dirty during the ferment.
Used to create an airtight seal in order to allow gas to escape without risking contamination while making beer, wine or anything else.
S-shaped airlocks are the “OG” airlocks for home beer and winemaking.
Please use boiled water to boil and disinfect the Air Lock before you using it. And clean it with water after using.
