Description
This double bubble airlock is a reliable fermentation tool designed to allow carbon dioxide to escape while preventing oxygen, dust, and contaminants from entering your fermenter. The dual-chamber design makes it easy to visually monitor fermentation activity and pressure changes.
Made from soft, BPA-free plastic, this airlock comes fully assembled with a snap-on cap, making it more secure and harder to misplace during fermentation. The vented cap allows the airlock to breathe while protecting the contents inside.
A rounded stem at the bottom provides a better seal when used with rubber bungs, reducing the risk of air leaks. Compatible with 38 mm screw caps and standard drilled bungs, this airlock works well for both winemaking and homebrewing.
