Twin Bubble S-Shaped Airlock for Beer & Wine Fermentation

Quick Overview

• PREVENT BACK-FLUSH: Use the S-Shape Bubble Airlock for Fermenting, Exhaust Seal Valves – Beer Wine Making Fermentation to prevent back-flush in the fermentation chamber (cut off outside air oxidation and allow gas to escape)
• BREW YOUR FAVORITE BEVERAGES: For secondary fermentation of homebrewed beer, wine, cider, juice, and more; Can be used for long-term repeated use on fermenters typically up to 20 gallons
• EASY TO USE: Fill part-way with water in the exhaust valve, affix to the fermenter with a brew barrel cover or rubber plug/stopper on the top of the fermentation container, and cover with a lid; Instead of unattractive and poor quality drilled holes in the cap, these airlocks release CO2 through the ridges inside the cap that keep it from forming a complete seal
• WATCH THE MAGIC HAPPEN: Clear, transparent plastic standard traditional fermentation airlock that gives you a clear look inside, so you can watch the airlock do the hard work for you
