Product Description

Principle: The one way airlock uses the principle of water seal, which can effectively isolate the oxidation of the fermentation medium by the outside air. The whole fermentation process is automatic fermentation and exhaust at normal temperature, without manual control, convenient to use, simple to operate, and can be reused for a long time.

The fermentation airlock is made of transparent plastic material that gives you a clear look inside, so you can watch the airlock do the hard work for you.

Each bubble airLock with cover which is preventing the entry of fruit flies, etc.

Product Features

• ✬Transparent plastic material fermentation airlock that gives you a clear look inside, so you can watch the airlock do the hard work for you.
• ✬4 pcs airlocks a set，each airlock with a cover. Prevent the entry of fruit flies, etc.
• ✬ The s-shape airlock use for secondary fermentation of homebrewed beer, wine, cider, juice, and more; Can be used for long-term repeated use on fermenters typically.
• ✬Effect: For red wine fermentation, it can conduct good air isolation during the second fermentation, and at the same time emit CO2; alcohol fermentation of honey wine, white wine and milk wine can prevent oxidation
• ✬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.
