Features:
The double bubble allows air to escape while preventing the flow of air, making it suitable for more delicious homemade beers. The S-type airlock has two vertical chambers connected by the exhaust valve. Cold collisions will not allow liquids to be absorbed into the beer.
The double bubble is strong and durable, so you can use this airlock to insert it into your fermenter for a long period of time to form a sealing system that prevents carbon dioxide from entering and harmful substances. Fill the marking line with sanitizer or fresh water and then use the drill plug.
