Klean Kanteen® Classic Cap Maintenance Kit

After a few years, it is not uncommon for the silicone seal in the matching lids of the Classic, Reflect, Kid and TKPro stainless steel water bottles from Klean Kanteen to become porous and thus leak. So that you don't have to do without your bottle and, in the interest of sustainability, don't need to buy a new one, you can buy this set of 2 O-rings for these caps online from us. This gives you two new seals that you can quickly and easily replace in the Classic Cap and your bottle will be reliably leak-proof again.
