About

One Way Exhaust: Airlock lets carbon dioxide escape during fermentation while helping keep outside air out, supporting a cleaner setup for beer, wine, cider, and secondary fermentation
Water Sealed Check: the air check valve uses a water-sealed design that helps reduce back-flush into the chamber during ambient temperature changes, making fermentation control easier for homebrew batches
Standard Fit: Sized at 4.72 x 1.49 x 1.49 inches, this homebrew airlock is made to fit common homebrew stoppers, corks, caps, plugs, bungs, and grommets with a hole for routine brewing use
Easy Setup: Fill the exhaust valve with water, insert it into the barrel cover or rubber plug, and close the lid to create a simple one way valve for home wine making and fermentation vessels
6 pack Supply: Includes 6 airlocks for batch brewing, replacements, or backup use, giving you a practical supply for home brewing supplies and everyday fermentation projects
