I recommend these!
They work great! I was about to throw two insulated cups away because they were leaking when I drank from them. I decided to try these rubber seals and they worked great.

Not thick enough
These rings do fit the lid for my Yeti tumbler, but they are not thick enough. They do not create a leak-proof seal. I would return them, but for $7.00, it's not worth the trouble.

Works for Rtic 20 oz. mug
These gaskets DO fit the lid of Rtic 20oz travel mugs they are just slightly thicker than the original one I had and that’s a good thing. The old one was compressed to the point where the sipping hole lined up with the handle or opposite side of the cup, making drinking slightly awkward. Now I have a few extra for when I over-torque the next gasket into uselessness.

Correct diameter, but was too thick for the cup I needed to apply it to.
I measured the diameter of the seal I wanted to replace very carefully before ordering, but while the diameter was correct, the thickness was off enough that it wouldn't allow the cup to close properly once applied, so it wasn't compatible. It would help to have the thickness as well as the diameter in the item description, in order to compare sizing. I ended up having to return these.

Perfect replacement part for our cups .
This is just what I needed! We have five people in our house who use a variety of cups with lids that need this size seal and some of them have gone missing. I was afraid I was going to have to replace all the lids (I did replace some) but having these gaskets available meant I could still use some of our original lids.

Silicone seals
They work for my cup which I’ve been looking for awhile not as thick as I needed but they do the job.

Diameter OK, but too thick
The diameter was correct, but it was way too thick. The lid no longer fit with it on.

They don’t fit my 16oz Starbucks cup but work great on the other random cups in our cupboard.
