C&Berg Pack of 3, 30 oz Replacement Rubber Lid Ring, 3.7 Inch Diameter - Gasket Seals, Lid for Insulated Stainless Steel Tumblers, Cups Vacuum Effect, fit for Brands - Yeti, Ozark Trail, Beast - Black

Was struggling to find a good replacement lid seal for a 30oz Yeti. Not only do these work great, but they're an excellent price as well!

Fits perfect for the yeti

Worked like they were suppose to. Rare these days

I was searching for replacement lids for my original edition RTIC tumbler without success when replacement *gaskets* came up in my search. Oh happy day!!After all these years the gasket had started to break down and leave black residue inside my mug. The mug will last forever - and the lid, which was not original, is in good shape. The replacement gasket has extended the life of my tumbler and lid by another 250,000 miles. I am very pleased to be able to re-use a perfectly good tumbler, lid, and handle that aren't being made anymore. No leaks!!Highly recommended!!

I absolutely love the cup. It is the only one I’ve found that was completely leakproof.The seals fit perfectly..
