This is the first universal lid for the Big Mouth Bubbler® family of fermentors. It was engineered by brewers to suit any of the Big Mouth Bubbler® fermenters, from the EVO 2 and Plastic to first-generation glass and even the Little Big Mouth Bubbler®!
This Big Mouth Bubbler® Universal Lid is just like a traditional carboy bung, only bigger! And it's just as easy to sanitize and put on your carboy, too. The ribbed silicone rings make sure that there's a positive seal to keep out pests, while the non-threaded design allows the lid to move which prevents out-of-control fermentation from dangerously pressurizing your fermentor.
Even better, the port is perfectly sized for all your standard homebrew tools, from a universal carboy bung and standard blowoff hose to a testing thief and auto-siphon.
And it's super easy to clean! Just pop it in the top rack of your dishwasher and run it through a standard cycle or you can also use your regular homebrew cleaners and sanitizers.
