Great idea for a carboy. I still do my fermentation in a 6 gallon bucket. I have used plastic food wrap for 5 years now, I just use 5 layer of wrap in a star pattern and carefully push the wrap down into the bucket. When it is fermenting, the plastic wrap is pushed up into a bubble on top of the bucket. Now that is impressive and you know without a doubt your yeast are working pretty hard.
I almost exclusively use S shaped air locks. Because other types are unavailable for me. I just ordered a few of those three piece air locks on Aliexpress, just curious to see how they work.
I normally just ran some tubing from an airlock or bung to a mason jar of water, but as you probably know this can get a little funky as long time passes. So, thanks for this - a solid clean investment. For those interested, as of the date of this post, they go for 12.99 from the link listed in the description.
I just bought a few of the 2 piece ones, after seeing this video. They are the same ones you show here. I'm a bit concerned in that they seem to let air in as well as out. Specifically, there is a seam under the flap which prevents a proper seal. Is this normal? Does it pose an issue? Thank you for the great content!
1 gallon carboys normally use a size 6, I'm only seeing these in size 7 or 10. I have tried using other size 7 bungs meant for regular airlock but it doesn't go well. I mostly make 1 gallon batches as well, but I can't find them in the smaller size.
Well, I tried it and have to say... slippery when wet. I was able to get the airlock on and deep as presented in the video, however the next morning when I checked on the brews. The silicone airlock had popped off. Took me by surprise and I popped it back on dry and I found that it was much harder to get the airlock back in to the initial depth I had it in. But my only suggestion is that don’t put it in when the silicone is wet.
No, but we usually ferment open (paper towel rubber-banded over the carboy neck) the first few days of fermentation while it is most aggressive. Been doing that for many years now. In the couple of times I've had foam sputter through it, it's done a good job of trapping it mostly. A quick swirl in sanitizer and it's ready to pop back on.

Good stuff!
Anyone know where you can buy these in the UK?
Still unavailable… any other recommendations?
Didn't know these existed! What about cold crashing? Any issues with these if doing that?
How are you getting the bungs so far into the Carboy mouth?
Mine only go halfway at most.

Are they unavailable?
Is there one that fits a PVC bucket lid?
But I love bubbles...hehe
Anyway, question is, how well does this work with reverse pressure?
update 3 years later, only sellers on Amazon selling them for $54 a piece lmao
Thanks for the tip! Shopping around for them right away. Well worth the initial investment.
Thank You!! We are now bunged all the way, bye bye bubblers!

One guy I met recommended filling the airlock with Vegetable glycerin as it never dries out.
Interesting choice. Hmm!
That's an awesome idea, cheers
Hey how do they work inside? what makes the air or other stuff not enter inside?
cuz it works as a one way valve
isn't it great t get a video that doesn't actually explain how the thing works and an answer to the specific question that "it just does? "

I also have the same concern, what has been your experience using it?
@@MrPenroy I sliced off the excess silicone with a razor blade, and only use them for relatively short term storage or during active fermentation.
That's what i thought.
I like tha "S" type sealers.
do these work well with 1 gallon glass carboys? I've seen mixed reviews on that, with some stating that they pop out easily.

Please send us the link to buying 'breathable silicone bungs' thanks DTM👍
Mahesh Lund They’re super easy to find on Amazon or Google Shopping these days. :)
...ahhh bungs!!! the joy of living in a country without Amazon (Ok, in a country where the delivery fee is standard at twice the object price)....
Cos we love watching the bubbles
Loose lids and rubber gloves with one hole. It gives you the finger when it's ready.🤪
anyone had issues with blowout for these?

Still i gotta see bubbling...i gotta....
Once you go silicone airlock you never go back!
