DetailsThe 3-Piece airlock is the best choice for the primary fermenter, since it comes apart for easy cleaning in the event of a blow-off.
Fill to the line with boiled water or sanitizer to create a closed fermenting system that allows CO2 to escape, but does not allow air back in to contaminate your beer or wine.

Plus they seem less fragile than the S type air lock.May 22, 2013Good simple airlockWorks well, keeps O2 out and gives CO2 a place to escape.February 21, 2013Good AirlockEasiest to clean of the ones I have used, gets the job done and doesn't seem to be flimsy or easily broken.October 30, 2012Works ok but not as well as S-Bubble typeThese work ok but I have found the s-bubbler type much easier to use. I have heard some negative comments about this type of airlock "blowing off" at times. If your airlock is blowing off (wine making), then you are transferring to a carboy too fast from primary fermentation. I always leave my wine in open primary (covered with cloth) until specific gravity drops significantly and have never has one of these blow off.June 2, 2013Best in my opinionthese are the best airlocks and the quality is great. easy to clean and sanitize.November 3, 2012good product for a good priceI've not been making wine very long but I do like the 3 piece airlock. I managed to break the first one while lifting the carboy up on to a table for siphoning. Unfortunately, the airlock caught on a sleeve and snapped off. Luckily the break was low enough to be able to continue using the airlock until I could get another. All in all, the 3 piece airlock holds up very well.February 21, 2013I have like 10 of theseWhen I started brewing I didn't know about the s-type airlock, so I used these on all my primaries and secondaries. Now I only use these on my primary. I've never had a blow-out, but just in case it happens, these airlocks come apart for easy cleaning. I kinda wish they came in clear colored plastic (at least the two small pieces), because they can be kinda hard to find in a bucket of sanitizer!June 5, 2013Basic and functionalYou can easily take apart the airlock and clean it in seconds. This model is great for any of your carboys as well as the lid to your primary fermenting bucket. It is a very simple, basic piece of equipment but also the easiest to clean and use._x000D__x000D_Make sure you have the same number of airlocks as you do fermenting buckets and carboys... you do not want to get stuck filling up your bucket on a brewday only to realize you don't have an airlock handy!November 4, 2012Works wellNever had a problem with liquid getting back into fermenter but use everclear so if it does then no real harmFebruary 22, 2013

I like to use for blowoff hose on it sometimes.BEST ANSWER: its all 1/2" ID from what I have read.what size stopper should I use for a gallon jug I ordered from you?BEST ANSWER: #6 stopper works well.Do you put cover on to fermentBEST ANSWER: If by cover, you mean the cap, then yes. It prevents any nasty dirt or such from falling in. It's vented enough to let the gas escape. I've used it for multiple fermentation runs.
