3 Pack Replacement Rubber Gasket Seal Ring for 20 oz Insulated Stainless Steel Tumbler Lids fit for Yeti, Ozark, Beast, KOODEE, SUNWILL, Umite Chef, BPA Free (3 Pack)

None of the gaskets listed for sale mentions the Built brand stainless steel insulated tumblers, whether these will fit or not. I took a chance with this order and was pleasantly surprised that these gaskets were a perfect fit for the Built 20oz tumbler, which can be purchased at Walmart. I am a happy camper with this find.

These are by far the best replacement gaskets I have used. I have bought everything from the Yeti brand gaskets to no name brand. These are great! The fit my Yeti, my Hogg and my Ozark Trail. I'm sure they also fit Magellan and other brands because my lids are interchangeable. The best thing, for me, is the fit snugly BUT not so tight that the lid is difficult to go on or come off OR won.t even go on correctly like some have in the past. And the price can't be beat!

Works OK, gasket needs to be about half a millimeter thicker.

Fits my 20oz Ozark Trail tumbler perfectly! Easy to replace old one. No leaks.

Good quality

Fit perfect, and does not leak.

Does not fit yeti 20oz properly. Leaks. Won't stay on.

I am bad about breaking them when cleaning. I'm picky about clean. I think I stretch them to Much. But I want them clean. These are a good replacement. I will be ordering more. It's a lot less cost than a new tumbler.
