Fastrack Twin Bubble Airlock for Fermentation | Hydrolocks for Fermenting Wine and Beer Making | BPA-Free Cylinder Airlock Used for Brewing Wine, Beer, Pickles & More | Transparent Airlock Set of 2

• AUTOMATIC TRANSPARENT AIRLOCK: FastRack airlocks are stronger, more transparent, and made of food-grade materials. You will easily see the entire fermentation process! Due to the airtight design of our fermentation airlock we isolate the air and prevent oxidation. Fastrack brewing airlock exhausts automatically at room temperature without manual intervention.
• EASY & SIMPLE TO USE: Insert the assembled airlock into the hole of the rubber stopper that fits your current jug or carboy. Fill the Bubbler Airlock with water and insert the drilled stopper or bung to vent gasses during fermentation. The airlock cap should always stay on top when in use to allow gas to escape and prevent the water inside from quickly spilling out if tipped over.
• HOW IT WORKS: Airlocks enable CO2 to be released during fermentation and trap oxygen from entering the fermenter. The bubbler style airlock is the preferred airlock for secondary fermentation, as it is possible to monitor the pressure inside the fermenter, and is the go to winemaking airlock.
• WIDELY USED: The fermentation airlock can be used in various fermentation projects to preserve food as well! The brewing airlock can be used to brew craft beer or wine, but also used for sauerkraut, kimchi, etc.
