Where can I find replacement hardware?

I would try on here, reword your inquiries if you don't find it the first time example bail closing for canning jars.... hope this helps

Are these for canning?

I would say no. These are gaskets that seal by pressure of the top lid against the jar rim. For canning you need the heat seals that create a vacuum seal like the Ball brand canning rings and inserts.
