Big Mouth Bubbler® Universal Lid Replacement Seal
From EVO 2 and Plastic to first-generation glass and even the Little Big Mouth Bubbler®, ribbed silicone rings ensure a completely air-tight seal. Easy to clean, just pop it in the top rack of your dishwasher and run it through a standard cycle. You can also use your standard homebrew cleaners and sanitizers.
Fits the Big Mouth Bubbler® Universal Lid single- and dual-port configurations.
**This replacement seal is only compatible with the Big Mouth Bubbler® Universal Lid, it will not fit lids from earlier versions of the EVO 2, or standard plastic lids for Big Mouth Bubbler® Plastic Fermentors.**
Fits and works well
If you install the seal wet and with the smallest fin to the bottom and largest at the top, the lid will often push itself out of the bottle.
Turn the seal over so the largest fin is on the bottom and it seals MUCH better, going in with a positive pop and it is actually sometimes hard to pull the lid off.
I was not happy with it in fact i found it use less.
The team packed the big mouth bubbler very well so that it is having a save and unbroken arrival at final destination
I purchased the Single & Duel port lids and have used the Duel port with a 6 gallon plastic BMB. Fermented a batch of Hard Cider and the lid sealed fine!
