Description

Fits PET Carboys. A breathable Silicone stopper that acts as both a stopper and an airlock. Unique design allows CO2 pressure to escape but keeps Oxygen and airborne contamination out. Quickly became our stopper of choice for wine. Used by numerous commercial wineries. Also has great application for beer ferments: Will create a vacuum if fermenting wort cools (as opposed to pulling water in from your traditional airlock.) Air tight seal is great for extended fermented lager when CO2 production is still present but very slight.

I have tried a bunch of different ones so far, and these by far work the best.

I use PET carboys that use a #10 bung. I accidently bought the smaller one (for carboys) a while back. Pet carboys flex a little when you move them around and fluid from your air-lock can be sucked into the carboy. Not good. I use my small breathable bungs on gallon jugs. (so I did find a use for them)

Will this fit on a 30L Speidel fermentor in place of the air lock?

BEST ANSWER: The #10 Silicone Bung does not fit on the 20/30L Speidel fermenter.

Love these
I fell in love from the first moment I used it in my Fermonster. Seals perfectly and easily. No need to monitor sanitizer level over long fermentations. No bubbling sound. No risk of suck back.

Love love love these things
After much hemming and hawing, I picked up 3 breathable bungs for my wine Better Bottle carboys. I was sent 2 breathable and 1 solid, but that's ok, since I use the solid one on the oldest wine. I did a kitchen renovation in the fall, and used the 3 bungs and 1 airlock, and it was so nice only having to watch 1 airlock. The other awesome thing is that I can use the Brew Hauler to pick up the Better Bottle carboy without the bung sucking in whatever's in the airlock - the breathable and solid bungs seal it up so that the carboy doesn't flex during the move up to the counter for racking.

I bought a fourth bung to go on my fourth carboy so I don't have to deal with the airlock other than during fermentation. I'm a happy girl.

Mistook for barrel size
Not necessarily Morebeer's fault, I should have look farther into it but I assumed these were the same (colored) breathable bungs I have purchased in the past that fit standard wine barrel bungs. Unfortunately I cannot find those here anymore.
