The 6 Best Airlock caps (2023 reviews)

We are personally inclined towards masontops airlock cap, it is not so pricy, but it overachieves its purpose and outstanding in important aspects. Silicone retains odors, not truly food grade. These lids are made for fermenting Sour Kraut and for burping when there is too much gas pressure build up. The lids work perfectly and clean up quickly. It comes with the silicone tops and the glass fermenting weights. The pickle pipes are made to let the jar "burp", to let out the escaping gas without juices running down the side of the jar.

The glass fermentation weights are perfect and also easy to use and clean. It is good to keep the veggies under the liquid. These are maintenance-free and their low-profile design makes them easy to store in cupboards and drawers.

Why We Like This:

Works on regular and wide mouth jars
Allows co2 to escape easily while keeping all veggies under the brine
Perfect fit for regular mouth mason jars

Best For Mason jar: Zazolyne Airlock cap

Buy on Amazon

Best part: zazolyne airlock cap costs comparatively low and it is available to ship in 24 hours. Different than other normal S shape airlocks in the market, its made of healthy material, more harder (no fragile)and more transparent. These have the best gaskets. This new type of dust cap has a zigzag design on the surface and will not slide when opened. There are 3 buckles inside, press it down gently, you can close it with a snap, pull it up and rotate to open it. It provides a great seal.

These do not need the holes in the top because they vent differently than the ones with clear caps. The lid does not need to be drilled as there is a gap around it, which allows the gas to escape.

Improved cap easy on and off
Good investment for long term
