I am replacing the original gasket that developed a tear on the edge. This fits the lid perfectly and provides a nice tight seal on the tumbler. UPDATE 4 1/2 years later: I purchased these to replace original Yeti gaskets that had torn. I have since purchased complete third-party replacement lids for my indestructible Yeti tumblers. These lids started having trouble by being too tight making them hard to remove. Or, they had the opposite problem of falling off because they didn't fit tight enough. A problem I have previously encountered is that the Yeti gaskets are tapered, so it is possible to put them on upside down (as shown in another reviewer's photo). Still, even oriented correctly, my third party lids no longer fit well. I was ready to order some ridiculously expensive original Yeti lids when I started looking more closely at the problem replacement lids. The problem seems to be the quality of the gaskets. They had shrunk or expanded due to what I assume are inferior materials. The third party clear plastic lids themselves were fine (except for the magnets which is a different story). I remembered that I still had one of these Bay State gaskets in my coffee accessory drawer in the kitchen. I put it on a problem lid and was astonished that it now fit perfectly. Not too tight and not too loose. Just a perfect fit. After sitting in the drawer for more than four years, it still worked perfectly. So I am buying more of the Bay State Importers brand and I feel compelled to update my original review.

Fits our 20oz yeti lids no problem. Seal so well lids are tough to remove. Better than the originals.

Llegó muy bien, tuve un error con la medida pero al final si quedó en el vaso.

YETI 10OZ 295mlに使っているが、値段以外は満足。 純正のゴムより高さ方向にやや薄く、密閉度もやや劣るが、自宅で使う分には支障無し。
