Fill the Bubbler Airlock with water and insert in drilled stopper or bung to vent gases during fermentation.
"Bubbler" style airlock makes a gratifying "bloop" noise during active fermentation. It is the preferred airlock for secondary fermentation, as it is possible to monitor the pressure inside the fermenter.
To use: Insert assembled airlock into the hole of the rubber stopper that fits your current jug or carboy. The airlock cap should always stay on top when in use; it has several small holes in it that allow gas to escape but prevent the water inside from quickly spilling out if tipped or jostled.
it's hard to evaluate a airlock, it does what it's supposed to do. But the bigger picture is that the order process, follow through, and customer service is excellent. I thoroughly trust that when I order from Northern Brewer, I will be happy with my purchase
Works! Fun to watch while having a home brew😉
works on my big mouth bubblers with the stoppers, to small for the hole in my bucket lid though
The device worked perfectly.
Excellent purchased several
