Airlock Grommet

This standard brewing airlock grommet fits into a suitable fermenter-lid opening and holds the airlock securely while helping maintain a seal around its stem.

How to fit it

1. Check that the lid hole and grommet size are compatible.
2. Press the grommet evenly into the clean lid opening.
3. Insert the airlock stem carefully so the grommet is not pushed through.

Helpful addition

Use with a compatible Bubbler Airlock. Replace a hardened, split or loose grommet if it no longer seals reliably.
