  2. Tophat Grommet
    $2.70

    Tophat Grommet

    The top-hat or T-shaped grommet is a popular choice for use with an airlock in a fermenter lid. Tophat grommets are more robust than the black doughnut shape alternatives which can become damaged, however they are more easily popped out if there is excessive pressure build up in your fermentation vessel due to a blocked airlock.
