Klean Kanteen O-ring gasket for Pint and Tumbler lid

The silicone seal on the Pint and Tumbler Lid ensures that the lid sits securely on the drinking cups and prevents spilling during transport. Through contact with tea, coffee, and other colored beverages, the silicone ring can become unsightly over time. Thanks to this matching O-ring - an original Klean Kanteen spare part - you can easily replace the seal yourself, and the lid will be fully functional for your Pints and Tumblers again.
