Air Lock Twin Bubble S Type

  • $2.99

One piece S-Shaped Airlock. Fill the Air Lock with water and insert into a drilled stopper to vent gases during fermentation. Features a smaller chamber so you can closely observe the CO2 rising and with that, the rate of fermentation. Also handy when you are cooling a beer as there is less of a chance of getting water sucked back into the fermenter. Innovative S design prevents back flow.
