Repair steps
Check the bottle and lid
Empty the bottle and separate only the lid parts the maker identifies as removable. Do not use this guide for a pressurized or insulated bottle with a damaged body.
Remove the seal gently
Lift out the loose or damaged gasket with clean fingers. Do not cut or stretch it, and keep it away from children and pets.
Match a food-safe replacement
Match the gasket to the lid’s exact model and groove. Use a food-contact-safe replacement approved for that bottle; do not substitute a generic ring that only looks similar.
Reseat and leak-check
Press the clean, dry gasket evenly into its groove. Close the empty bottle, turn it upside down over a sink, and check for leaks before using it with a drink.
