Product Description

Isolate your wine or beer from air, discharge CO2 gas, and prevent contaminates from tainting the brew with the G. Francis S-Shape Bubble Water Airlock Grommets - Exhaust Seal Valves for Fermentation of Homebrew Beer and Wine Making. These grommets are for secondary fermentation of homebrewed beer, wine, cider, juice, and more and can be used for long-term repeated use on fermenters. Sterilize by boiling water and disinfecting prior to use. To use, simply fill exhaust valve 1/3 full of water and gently insert a brewing bucket lid. The fermentation process will generate bubbles through the exhaust valve and discharged to the outside buckets. The transparent plastic airlock is standard for fermenters up to 20 gallons.
