Includes 13 QRP BPA-FREE FOOD GRADE WHITE SILICONE Grommets for any brand Mason jar plastic caps (1/16" groove). 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). Grommet center hole is 3/8" and is the standard size for Fermentation Airlocks. The 1/16" groove is too narrow for glass lids.
