Plastic airlock with dust cap
Allows CO2 to escape
Prevents air from contaminating your beer or wine
Priced just right
These are good and perform well.
We used to make kraut in a large crock. No more, with grommet lids, these airlocks and gallon jars we make wonderful tasting kraut in variety of flavors. Thank you for having all the supplies I needed.
I will buy these again.
Nice standard air lock gets the job done at good price
