A friend gave me 2 boxes of kerr jars that are about 25 years old. The boxes were unopened with their original lids. The sealing ring is a grey material instead of the reddish stuff that I'm accustomed to. Is it okay to use these lids? Will they seal properly?
Using older lids?

Replace the sealing rings the rest should be okay.

Actually the flat lids may be fine, if the rubber seal is still viable. I've bought many from estate sales where the boxes were stored in sheds and they worked fine.
Test by warming up a couple of them and put on jars filled with water and process. See how they hold up. If they fail chances are the rest are bad too since they were stored together....and vice versa.

I like mcnerd's idea. I think they are fine, as long as they aren't stuck together, but trying them out is a good idea.
And the rings will last a lot longer than the new ones, which rust as soon as you look at them.

Maybe it was the (removed) BPA that was protecting them, though I haven't noticed any new issues other than the cost in buying them.And the rings will last a lot longer than the new ones, which rust as soon as you look at them.

I don't think so, mc. I think it is cheap Chinese steel, myself.
The BPA, as far as I know, is still present--it lines the inside of the flats.

Here, here. Those new silver rings rust after one use, but the rings my mother gave me 25 years ago are still pristine. Go figure.And the rings will last a lot longer than the new ones, which rust as soon as you look at them.
