Replacement Gaskets Compatible with Thermos Stainless King 16 Ounce Travel Tumbler Mug Gaskets Seals, Fits Stainless King and Comparable Travel Tumblers Mugs - Food Silicone Seal Without Leakage (2)

Did the trick. For some reason I lose one of these now and then.

I'm so glad I found these. I drink coffee and ice tea, so the seals on my cups look really sad. These fit perfect on my Thermos insulated cup.

If you own a thermos just replacing the inside washers will work for another year!

Good fit for my travel mug

They somewhat fit, but the close does not lock into place. I put them in correctly, tried flipping them, the old gaskets allow it to lock into place, but the new ones do not. Just leaves a flimsy feel for the lid really

Replaced the gasket in my cup because the original ones were getting harder to clean. These gaskets were exactly what I was looking for. A package of 2 gaskets was a plus.

Es UN poco grande se suelta rápido y no sella correctamente

Sure not much to say but they work well and we are happy to extend the life of our favorite thermal mugs! They do seal well and stopped the leaking we had on our several year old seals.

worked great in our cups which we had purchased second hand - old seals were badly stained. new seals = new life for cup

Great quality but then realised I could have bought the brand new Thermos mug for the same price!

I'd lost a gasket for my mug after putting it in the dishwasher. These ended up fitting perfectly as replacements. It also worked well to renew the other gaskets in the mug as there was some "patina" from regular use.

They don’t fit well to high having to yous them

Used to replace same in older model thermos mug. Exact fit!
