Gaskets for ThremoFlask straw lid

I wish I'd known about these sooner. I once threw away a water container I loved because the gasket was just impossible to clean. These look so fresh and have stayed clean, but I know I'll eventually not be able to clean them well and can just go to the next one that's in the multipack.

I add electrolytes and flavor to my water bottle which does, even with regular cleaning, shorten the life of the gasket. These gaskets fit perfectly in my ThermoFlask and are very easy to install.

Perfect fit for the ThermoFlask kids 16 oz water bottles purchased from Costco

They fit just right (compatible as promised), and installing them was a breeze — no wrestling, no weird stretching, just pop them in and get sealing. The material feels sturdy but flexible, and they’ve held up great after multiple uses and washes. Honestly, it’s the kind of purchase you don’t think much about until your old gasket gives up mid-smoothie and you end up wearing half your breakfast. These saved the day — and my shirt. Great value, solid quality, and now my blender is back in business. Would definitely buy again... but at this rate, I won’t need to for a while!

Not the right size. But nice et great product.

Solved the leaking problem

These did not fit any of my bottles

En realidad no es compatible con termoflask Tuve que ponerle dos. A ver si funciona Por lo menos se sintió que sello la tapa

Es para mis nietos y le encanta
