This is the traditional one piece "bubbler" air lock.
Attach to carboys and fermentors to prevent oxidation and spoilage of wine and beer. Acts as a valve which allows carbon dioxide gas to escape while keeping air out.
This 3 piece air lock comes apart for easy cleaning.
Air Locks are usually coupled with the correct size rubber bung for your fermenting vessel. Please see our chart for available sizes.
