4pcs 09915 Pressure Cooker Overpressure Plugs, Durable Plastic Replacement Parts for Presto Pressure Cookers & Canners (Black)

These worked for my presto pressure cooker.

They work fine

These are acceptable but they fall out easily so I've lost a few. I am looking for a better brand that works more efficiently.

I actually picked these up to use as bumpers on my mailbox because the lid if opened just so opens straight up and will not close so I picked these up to use as a bumper to prevent opening up as much but not cause issues. Works great for this. They are super tiny, but also nice and bouncy/squishy is a good rubbery sort of way, while also being durable. I do have a pressure cooker that this also works with, I just got these for multiple uses.

works perfectly

Don't fit tight enough, comes out with slight touch/pressure
