When using wide mouth jars for storage, these lids are a lot more convenient than 2-piece canning lids. I'm using 64 qt jars to culture marine phytoplankton, which requires two 1/4" holes for an airline and vent. Metal canning lids, once drilled, would begin rusting quickly when exposed to the saltwater splatter. That's a non-issue with these plastic lids. I can't speak to their sealing capabilities, but they're easy on, easy off, and I like them.

Great choice!

Love, love, love these lids. They are great quality, easy to use and a great price. Great alternative to the lids and bands that come with canning jars. Of course they are not to be used for canning, but I love using them for storing things in the kitchen, especially my fresh pressed juices. The only complaint that I have is that they are not leak proof. Still would purchase again and again!

If the jar is wide mouth canning the lid fits. It may not seal tight enough to prevent liquid leaking if the jar is not upright. Other wide mouth jars don't have enough turns for the lid to fit on. I use my 2 quart canning jars and these lids for fridge storage of soup recipes. Those are awesome!
