Tony's Tips

This Airlock Grommet will support the stem of the more lofty "Bubbler" Airlock due to its greater Aperture Depth as well as the shorter "Handy" Airlock normally used with  Fermenting bins with the standard shallow grommet. Wet the seal and Bored hole with cooled boiled water before fitting and inserting the Airlock Stem for improved sealing and smooth handling.
