2 bored PET demijohn lids with rubber grommets fitted for homebrewing wine, cider and mead.
2x plastic caps with pre-fitted grommets, suitable for PET demijohns. Using a cap with a pre-bored lid means you don't need a rubber or cork bung for PET demijohns. Instead the grommet ensures that, when you fit the airlock inside the lid, an airtight seal is created and fermentation is able to begin.
The hole with grommet fits all standard airlocks.
2 bored lids in a pack.
