Two pack Italian twin bubble airlock set with grommets and universal carboy bungs for fermenters. Designed to fit 3, 5, 6 and 6.5 gallon carboys, these airlocks allow CO2 to escape while keeping contaminants out for clean, reliable fermentation.
North Mountain Supply Italian twin bubble fermentation airlocks with grommets and universal carboy bungs provide a complete solution for managing fermentation in a wide range of carboy sizes. This convenient 2 pack is well suited for home brewers and winemakers who run multiple batches or prefer to keep spare airlocks on hand.
Each set includes:
2 Italian twin bubble airlocks
2 grommets
2 universal carboy bungs with pre drilled holes
The universal carboy bungs are designed to fit standard 3, 5, 6 and 6.5 gallon glass carboys, making them a flexible choice if you use more than one fermenter size. The pre drilled bung holes accept the airlocks directly, creating a snug fit and a secure pathway for gas release.
The included grommets are intended for drilled lids and help create a double seal when used with compatible plastic buckets or fermenting vessels. This tight, leak free interface channels CO2 through the airlock while helping keep oxygen, dust and airborne contaminants out of your fermenting beverages.
Italian made twin bubble airlocks are easy to use and read. Simply fill to the marked line with sanitizer or boiled and cooled water, insert into the bung or grommet, and begin fermentation. As CO2 is produced, it escapes through the airlock in visible bubbles, while the liquid barrier protects the ferment from outside air and microbes.
