4 x 09915 pressure plugs for pressure cookers, durable plastic replacement parts, compatible with Presto pressure cookers and jugs (black)

It's doing the job. These work great on our pressure cooker.

Justo lo que necesitaba, muy buena

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

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.
