Lid Grommets, 2 pces

Not all grommets are created equal. We selected this grommet after struggling to find one that would fit a 1/2" hole in the lid, and have a sufficient size opening to allow a standard airlock to be inserted. The airlock fit is tight but that is ideal for ensuring there are no leaks.

For convenience, we have bagged these in pairs so you will always have a spare.
