2.3 / 5.030 ReviewsGreat lid but, has a draw backThe product is great however, the fermentation can cause enough pressure to raise the lid off. I would highly suggest a clamp ability to maintain a tight seal.September 8, 2019Purchased

3 months agoFor the love of God, please make a lid that worksI have several of these, and they never seal. Ever. Wet or dry, the pressure always pushes them up. Back when bubblers first came on the market, they had a decent lid that screwed on. Whats wrongs with going back to that? You really shouldn't have to use things like tape or weights to get it to work. This isn't hard, just make something that works easily, every time.April 20, 2019does not sealdoes not stay down. does not seal.
I see why people were using straps to hold the lid down.
Is anyone having success with this lid? I would like to know how.April 4, 2019Purchased
8 months agoBig Mouth Bubbler® Universal Single Port LidThe lid is great. You just have to set weights on it for the first time you use it, so that it stays completely down on the mouth. Otherwise, it will pop up on you. One pet peeve that I have was that the EVO 2 Big Mouth Bubbler no longer comes with this lid. Instead the vessel comes with the cheap screw on lid that doesn't seal as well as the Universal lid. You will probably have to buy this separate.December 9, 2018Purchased
11 months agoBuy the screw on typePoor seal batch dislocates it easily in secondary. Have to mitigate with duct tape - which is a pain in my arseNovember 14, 2018Purchased
1 year agoUpdated Bubbler lid with silicon rubber sealThis new lid looked like it should seal better than the screw on plastic with foam seal lid that came with the Bubbler , but it does not. 3 batches showed no gases to blow off bottle or air lock after 1 day of high activity. Adjusting lid up and down resealed it 1 time so gas was observed and putting 10 lbs of weight worked once for the rest of week . I might try glue on the smooth inboard side of the seal next time. I used a fuel tank O-ring under the stock lid and got pretty good sealing but this should work better if I can solve the problem of it bypassing gas.October 25, 2018Purchased
1 year agoWorst design everEpic fail...why would anyone design a lid that doesnt stay in place/slides up. Go back to a threaded lid. Its a no brainer peopleSeptember 19, 2018Universal Big Mouth LidsWhen I first used these & wasn’t real happy. Then I read another review someone said to turn the silicon gasket over. I tried this & it works great. I turned gasket upside down then wet it with sanitizer (goes on easier) & no creeping up. Before doing this I had to add weight to keep it down. Not now. Buying a few more.February 23, 2018great in theory but awful in executionI was horribly disappointed with this product. I was even more disappointed when I went to order Hills School ring and cap only to find they are no longer available. The unit consistently backs itself out of the bubbler. I was advised to reverse the Rubber seal but even that doesn't work and unfortunately I ended up cracking one of my plastic bubblers trying to work with this darn thing. my advice to people would be to not even waste their money purchasing due to the risk of contaminating the beer because of a poor seal and the extra steps you have to go through to keep the darn thing in place. I really wish they bring back the old ring system.May 22, 2017
