I got backups to my grain grinder too….for the same reason.
My cheap thrift store purchase of a pressure cooker [not canner] was simply so that I’d have an extra weight thing-a-bob. In case the first one on my got lost.
Anyone saving extra seals for canners….if you’re in arid country like I am, put them into your fridge. Not freezer, just fridge for the humidity. I keep hair bands, and other rubber type things in a crisper drawer. Else they dry up and crack quick. I should be keeping Bandaids in there too…since they go gooey way too soon. 🙁
