Better than rubber!

I bought a bunch of rubber grommets and they would split apart after one use. These worked great. These have enough pliability and being food grade silicon won't add a rubber flavor.

Works great!

These work great for proper seal in a lid of a bucket or a gallon bottle for your airlock. I am very pleased.

Good product works as described.

It fits well on the airlock and the 5/8 inch holes in lid. Solved leakage on lid.

Exactly what I needed

Use them on plastic mason jar lids, drilling 5/8" hole

Work great

Much better than Rubber stoppers

item as stated

They work well and are as advertised

Fermenting beer or wine

They are made for airlock grommet for fermenting beer or wine. I also used it to ferment food in the Mason jar. It was awesome.The air lock is inserted into the gasket to completely ensure the sealing of the air lock,prevent bacteria from entering, fermented food tastes particularly good!!!
