Big Mouth Bubbler® Universal Lid – Dual Port

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. Dual Port design allows for the ability to continuously monitor temperature with a thermowell/temperature probe why still having an airlock in place to release CO2.
Available in single- and dual-port configurations. Dual-port gives you the ability to constantly monitor temperature through one port while allowing CO2 to escape through the second port.

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.
