S-9892 pressure cooker gasket seal, fits Mirro.superus

I wish I had gotten a new one a long time ago; this new one fits so much better and thus seals so much faster. It is terrific!

You know, after writing that stunning review I've had 3 bad experiences; this new gasket is thinner than the original 1970's gasket, and 3 times it's rolled over when the lid is "screwed-on" and the pressure has forced it's way out the side of the lid, rather than out the top hole, which is scary and could be dangerous. I know the gasket is placed correctly and the lid is on correctly and the pressure hole is open; so it's just an unfortunate thing that this gasket does not fit and now I'm afraid of my pressure cooker with this gasket ...

Since I could not find this product locally; I ordered two thinking the old Mirro
would work for years; but neither would hold pressure. Went back to my old seal which
is about 12 years old and about shot; but will still hold pressure.

I felt paying $5.00 for shipping was ridiculous when the postage on the package plainly said $0.50. I have been unable to get the gasket to seal properly, despite my 50+ years of using a pressure cooker. I know how they work!
