Silicone Airlock Grommets for Fermenting Jars - Bulk Quantities

QRP's White Silicone GROMMETS are designed to fit any brand of Mason jar plastic caps, featuring a 1/16" groove. These grommets can be easily inserted into a 9/16" lid hole. However, a 1/2" hole may be too tight, potentially pushing the airlock into the lid and causing it to crack, while a 5/8" hole may result in a loose fit for the grommet. The grommet's center hole measures 3/8", which is the standard size for Fermentation Airlocks.

PLEASE NOTE: THE 1/16" GROOVE IS TOO NARROW FOR FIDO GLASS LIDS, so do not order these grommets for use with glass lids.
