The prudent sailor use them right now

them right now. The cult of keeping old parts
you don't trust is too bizarre. Anyway, those o-rings are good for years in actual use. I've used o-rings from the 30s that were in the original packaging without trouble (the key is that they were still sealed).
Always rotate your inventory.
