Product Description iThrow away those old rubber gaskets on your stainless steel tumbler and replace it with a new seal! These replacement gaskets fit most major brands such as Yeti Tumblers. Simply pull off the old ring then stretch the new ring in its place and let it seat in the groove for a perfect seal. Each package contains two new seals. Lid sold separately. Due to variations in tumbler lids our seal may fit slightly differently than your original seal. These seals do not fit brands such as Thermos, Big Bubba, Contigo, Kleen Kanteen, or Hydroflask.
