Review: They Seal the Deal 🌀👌 - 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!
Review: Perfect fit - Absolutely perfect replacements for water bottles. I rather replace than wash.

## Features

- PERFECT COMPATIBILITY: Our replacement gaskets are fit perfectly with ThermoFlask water bottle with straw lid in both 16oz 24oz 32oz and 40oz sizes. They're easy to install and use just like the original gasket. (Note: Please confirm your water bottle model before buying. NOT FOR Spout lid Water Bottle）.
- SAFE AND DURABLE MATERIAL: Our straw lid replacement seals part are made from high-quality, food-safe silicone that's BPA-free and odorless. They're built to last and won't wear out or warp over time.
- SAVE MONEY AND REDUCE WASTE: Instead of buying a whole new lid or bottle, simply replace your lost or damaged rubber gasket with our O ring. It's a affordable and eco-friendly solution to save money and reduce waste.
- PREVENT LEAKS AND SPILLS: A damaged or missing gasket can lead to leaks and spills, ruining your drink and making a mess. Always have a spare gasket on hand to ensure a tight seal and leak-free experience.

Very happy! These gaskets do fit the 24oz straw lid ThermoFlask. Wish they came with the small air vent plugs.
