Best For canning jar: Fermentology Fermentation Stopper

The fermentology fermentation stopper is the best reliable stopper on the market today. The sauer system uses a water barrier hosted in an inner airlock chamber to effectively burp lacto ferments through an automatic degassing process that creates an anaerobic environment. The airlock lid prevents air from getting in while allowing the gasses to seep out. It is made of food safe and high-quality plastics and silicones.

The airlocks are well designed,and the stopper plug for refrigerated storage without changing lids, completes the airlock system. It's sturdy without being bulky and does its job very well. The locks would work well for wine, beer. It is perfect for fermenting in because of their convenient size and popularity.

Best For fermenter lid: ONEBOM Fermentation Stopper

Buy on Amazon

The onebom fermentation stopper gives the top-tier stopper a run for their money by offering flagship specs at a much more affordable price. Silicone stoppers are great and the air locks are not so great if you have heavy fermentation they don't work maybe in a secondary they might be the Amazon does have a set of six that are really good and they work really good. The twin bubble airlock and the plug or cap acts as a seal so that gasses produced during fermentation can escape through the airlock while keeping the wort inside the carboy sealed from foriegn bacteria. If there is a vigorous initial fermentation it will go into lock and can't be cleaned easily.

These air locks are used on fermentation carboys to release CO2 without allowing air to enter the carboy. The tail of the airlock will not break when inserted into the bottle mouth. The plastic airlock is transparent. The grommets insert easily into a 1/2" drilled hole and once the airlock was placed in the grommet there is no co2 leaking from around the grommet or where the airlock enters the grommet.

You can see clearly when you ferment vegetables or beer

Keep the dust or insects out
Cover the lid to prevent the fruit flies from falling

These bungs do NOT fit in a typical 5 or 6.5 gallon carboy. The rubber is flexible enough to give a tide fit on the bubblers stem.
