Big Mouth Bubbler® Universal Dual Port Lid

The first-ever universal lid for Big Mouth Bubbler® fermentors. Engineered 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®, ribbed silicone rings ensure a completely air-tight seal. 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.

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.

The universal lids all use a:

Small universal stopper

Standard 6.5 rubber stopper.
