The first-ever universal lid for Big Mouth Bubbler® fermentors. Engineered by brewers to suit any fermentor in the Big Mouth Bubbler® family, from EVO 2 and Plastic to first-generation glass and even the Little Big Mouth Bubbler®.

The Big Mouth Bubbler® Universal Lid is just like a traditional carboy bung, only bigger! Just as easy to sanitize and set in place too. Ribbed silicone rings ensure a positive seal to keep out pests, while the non-threaded design allows the lid to move preventing an out-of-control fermentation from dangerously pressurizing your fermentor.

Better yet, 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.

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.

The universal lids all use a:

Small universal stopper
Standard 6.5 rubber stopper.
