DetailsThis S-bubble airlock is the preferred choice for secondary fermenters, as it allows you to monitor the pressure in the fermenter.
Fill to line with boiled water or sanitizer to create a closed system, which allows CO2 to escape, but doesn't allow air back in to contaminate your wine or beer.

1 month agoI like these better than three pieceI would rather have one of these on the top of my fermentors than the three piece one because they are simple and do the trick.March 5, 2019Purchased
11 months agoUndecidedBuckets and lids fitted for the air locks/bubblers were a complete fail according to M.S. they are not air tight, so why sell them to use with air locks...very disappointed, aside from that I can’t really give a positive or negative review on the air locks...they never bubbled so they could be awesome or junk....idk. I should of just bought the yeast and called it good...hopefully someone else doesn’t misinterpret/ mistake the buckets and lid sealing for use of an air lock.

Browse 5 questions Browse 5 questions and 8 answersHow do you hold the bubbler in the opening of the 6 gallon carboy?BEST ANSWER: Insert the airlock into a drilled bung. The 6 gallon glass carboy and 6 gallon PET carboy take different sizes, so be aware of that when you order the drilled bung.Are these or your 3 piece airlocks made in the US? Thank you!What kind of bottle does this fit onto, could find any info on the size it fits into?BEST ANSWER: The airlock fits into most universal bungs for glass or plastic carboys and will fit directly into the top of brew buckets without the need of a bung.Would this work for making sauerkraut in a 5 gallon food-grade bucket?BEST ANSWER: YepHi. Do I need to keep the red cap on the s lock throughout the primary fermentation?BEST ANSWER: Shouldn’t have to, but the red cap will keep or lessen the amount of moisture from the a rapid or aggressive fermentation from blowing the fluid from the air lock.
Thanks for asking.
