Grommet easily inserts into 9/16″ lid hole (1/2″ may be too tight, pushing the airlock into the lid may cause the lid to crack; 5/8″ may cause a loose fit for the grommet).

Use to add an airlock port to a container of your choosing. I know of several grommet offerings, most don’t claim to be food grade. That’s probably not a big deal considering that most of the time this gets little to no contact with your beer. Having said that, it’s nice to have a food grade option.
