I’m so glad I bought them. Like brand new again.
They work great. You really have to tighten to keep it from leaking, but the original did no better.

Great fit
Exactly what I needed

Not worth it
I have a 16oz thermos travel cup that needed the seals replaced. Bought these & they don’t fit the lid! The big ring is too large in diameter & the thickness of the other two seals keeps the lid “closed” even when setup for drinking.

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

Replacement Gaskets Extending the Life of Our Favorite Termal Mugs!
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.

They Fit My Thermos Drink Lock Lids!
I bought 1 set to make sure these fit my Thermos drink lock lids—and they fit!

They work mostly
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

perfect fit, great quality silicone seals for Thermos coffee cups
worked great in our cups which we had purchased second hand - old seals were badly stained. new seals = new life for cup

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