Fastrack Twin Bubble Airlock and Carboy Bung (2-Pack) | Fermentation Airlocks for Homebrewing Beer, Wine, Mead, and Kombucha

Works great. Great price b

Works good for wine jug

I recently bought this 2-pack of the Double Bubble Airtight Compartment and Carboy Cap, and I’m really happy with my purchase. The quality feels solid and durable, not cheap plastic at all. It fits perfectly and creates a tight seal, which is exactly what I needed.

Ordered two airlocks, but only received one. But did receive gallon jug with bing and cap for jug. I’ll call it a wash in my favor! I read the description more than once-said two airlocks and 0 about the other items. Guess have to try it out! Plastic airlock…

Been using these for three years and they’re still kicking so they still work rubber still good everything

Great for homemade wine making. I used these without the stopper on my primary fermenter and with the stopper on my secondary glass carboy. They are well made and work very well. I did notice the stoppers liked to slip up out of the neck of the glass carboy a little so I had to tie them down into the neck but this may be unrelated to the stopper itself.

Bought these a few years ago and still using them every year to make wine. If you haven't tried it, plant some vines and go for it. It's very satisfying.

I purchased these to use with my 1-gallon glass jugs (apple cider vinegar jugs). Unfortunately, the bung did not fit in my tiny hole. However, that is my fault. I truly didn't know and just hoped for the best! My rating does not reflect that as that is in no way the manufacturers fault. My rating is based off the quality. They are incredibly thin plastic - 1 individual piece arrived broken out of the 8 pieces I bought. Putting them into the bung hole and removing them from the bung hole truly makes me worry I will simply snap it off. I also had a problem of getting the water in the right location for the product to work properly. Mind you, there are no directions included. I tried adding the water before and also after inserting it into the bung hole. Before and after inserting it into the jar opening. No matter what method I used, the pressure of inserting it (and closing the path for air to move freely) would push or pull the water one way or another and it simply would not settle where it was supposed to be. On top of that, cleaning these is mildly annoying - not too bad though. However, since these bungs did not fit my jars, I ordered a different size (with success!) and also different 3-piece airlocks. The other airlocks were much more durable feeling and the bungs fit my jars perfectly. I did use one single 2-piece airlock with the newer bungs (interchangeable) just to thoroughly test it. I still didn't like the 2-piece airlocks. I would personally recommend getting either a more durable 2-piece airlock, or simply a 3 piece airlock. I would choose a 3-piece airlock any day over a 2 piece airlock. Overall, pretty decent for the price. I wouldn't recommend to others, but that's personal preference - not because it's a bad product. I know many people have an easy time with 2-piece airlocks. I just happen to find 3-piece airlocks far easier to deal with.

It only just arrived, so I only gave gotten to test the fit so far, but it's absolutely perfect. I'm brewing cider in a 23L glass fermenter. The bung I got from the homebrew shop just did not fit at all and I had to tape it down for the previous brew. This one fits perfectly, very securely, and the air lock fits just as securely. I was looking at caps and was astounded at their price in Australia. This fella will surely provide a better seal, though. And the hollow design means that it should fit a slight range of diameters with its ability to flex. Simple is best!

Muy funcionales, material resistente de buena calidad, fácil de lavar, cabe en la boquilla de una garrafa de un galón, muy útil para que las fermentaciones no se avinagren

These are actually great quality for the price. The rubber stoppers are good quality rubber and the plastic is decent quality as well. They work perfectly as advertised. I recommend for anyone interested in buying to check rubber stopper measurements and the measurements of the hole on your jug or carbon to make sure you buy the right size. Would recommend to others and buy again in the future.

Quality is good
