Replacement Gaskets for ThermoFlask Water Bottles

All You Need In One Place

PERFECT COMPATIBILITY: Our replacement gaskets are designed to fit perfectly with ThermoFlask water bottles with straw lids in 16oz, 24oz, 32oz, and 40oz sizes. Installing them is easy, just like the original gasket. (Please check your water bottle model before purchasing. Not for spout lid water bottles.)

SAFE AND DURABLE MATERIAL: Our straw lid replacement seals are made from high-quality, food-safe silicone that is BPA-free and odorless. Built to last, they won't wear out or warp over time.

SAVE MONEY AND REDUCE WASTE: Instead of buying a new lid or bottle, replace just the lost or damaged rubber gasket with our O-ring. It’s an affordable and eco-friendly solution to save money and reduce waste.

PREVENT LEAKS AND SPILLS: A damaged or missing gasket can cause leaks and spills, ruining your drink and creating a mess. Always have a spare gasket on hand for a tight seal and a leak-free experience.

CONVENIENT PACKAGE: Each package includes 4 replacement gaskets for ThermoFlask water bottles. For best results, wash the gaskets before your first use. (Note: This package does not include a mug or lid.)
