This red replacement rubber grommet is your airlock’s best friend, creating a seal with pre-drilled bucket lids. We suggest grabbing a couple because these rubber grommets have a habit of walking away when you need them most.

This replacement rubber grommet fits pre-drilled bucket lids.

Bought as a replacement for the original grommet that came with the fermentation bucket in the starter which seemed a little loose. Appears to fit slightly better
