2-Piece Fermentation S Type Airlock Twin Bubble with Grommets

Highlights

• The S-shaped airlock features 2 vertical chambers connected by a sort of drain trap. It does not suck liquid back into your brew when cold crashing.It`s strong and durable.You can use it for a long time.
• EASY TO USE - Fill the Bubbler Airlock with 1/2 or 1/3 water and insert in drilled stopper or grommet to vent gases during fermentation.It is the preferred airlock for secondary fermentation, as it is possible to monitor the pressure inside the fermenter.Package include 3 grommets. Pls order from other shop if you need the silicone stopper.
• Works great for home brew with a better flavor as it lets no air in but does allow for gases to leave. It can also work for fermenting vegetables like ferment cabbage to make sauerkraut.
