Newell, parent company of Jarden, producer of, Ball, Kerr & Golden harvest lids & jars is the best known US producer.
I have been happy with lids from Superb Manufacturing out of Ohio. They only make lids.
Tecnocap has also been around a while, their lids are unbranded, but I have found them to be of good quality. In the past they were indicated as US manufactured on the box, I do not know anymore, I have not received any lids from them for at least 2 years. They make a lot of the one piece lids where the lid and ring are all one piece. Like you might find on a jar of home style peaches at a grocery store.
I have used all of the above lids and been satisfied. I have used Chinese sourced lids as a test for comparison to US lids but prefer not to - even though they did seal when we did our part. They are thinner, I am not sure of their rust resistance, and I do not trust chinese gasket material or metal to be food safe.
Ball is the best known brand, followed by Kerr.
