    Product Details

    • Fermentaholics Fermentation Grommets: These dark blue rubber grommets are designed to hold all standard-sized airlocks, including 3-piece, Double Bubble, and S-style airlocks, and keep firm in place on fermenter lids for secure, sealed fermentation. Can also be used to seal blow-off tubes, tubing, or straws when dimensions are compatible.
    • Airtight Compression Seal: Creates a tight seal between the airlock stem and fermenter lid to allow CO₂ to escape during fermentation. Proper half-inch hole size is required for an effective seal. Choose between single pack or 20-pack. These grommets are ideal for setting up multiple fermenters or keeping replacements on hand.
    • Compatible With 1/2-Hole Fermenters: Suitable for use on plastic bucket fermenters, lids, and any drilled vessels used for beer, wine, cider, and other anaerobic fermentations with a half-inch hole lid. Need a DIY fermentation lid? Use a 1/2-inch drill bit to drill a hole in a lid you already have on hand.
    • Easy Installation: Simply press the grommet into the hole by hand; the airlock stem inserts directly into the grommet with no tools required. Proper hole size is required for an effective seal.
    • Durable Flexible Material: Made from a resilient rubber that maintains elasticity with repeated use and cleaning under normal fermentation conditions.
