Pack of 4-30 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, White by C&Berg

Searched long for a slightly larger rubber ring/gasket for Simple Modern 32 Oz tumbler. This tumbler’s lid is incrementally larger than Yeti and Ozark tumblers of similar size. This gasket fits perfectly and seems to be better quality than original. Nice tight fit - no leaks. Simple Modern is often a tumbler with a sports team logo on it. Also fits Thermal Craft 32 oz tumbler which is often a mug used for custom branding logo for companies or events. Cup brand symbol is a TC with a flame above the T.Hope this helps someone find what they need faster/easier. Good product, high quality, good price and buy 4 for like .50 cents more than 3.

So, upfront, if you have the same/similar BUILT mug as I do, these scores are not accurate. Please see below for information.These arrived right on time with four gaskets in one bag as I ordered, no damage. I have a BUILT mug (holds 8 cups) from Wal-mart (or Target, can't remember which) and the gaskets fit the circumference of the lid perfectly; however, they're not quite as thick as the original gasket. I don't hold this against the seller, which is why I scored five stars, as I wasn't quite sure if they'd work when I was ordering them but wanted to try anyway.I tried doubling them up (two gaskets instead of one) and it sort of fits okay. Still not as tight of a seal as the original gasket. My coffee and/or tea still stays hot (it doesn't seem to affect temperature loss). The only concern is the lid obviously doesn't stay sealed into place. Not a big deal, I just make sure I'm careful not to pick my mug up by the lid (bad habit of mine anyway).Again, even though they're not quite what I was looking for, this is my fault, not the sellers. If you have a mug in which these seals fit more snugly, I'd highly recommend these gaskets. My scoring reflects how pleased I am overall; if I can get a mug in which these fit, I'm golden.

Works great!

I was worried it would not fit on a 40 OZ cup, but it did.

What I found with my container was….it is a 30 Oz, purchased through Amazon 2-3 years ago, when I put one of the rings on the lid, tried to use, the lid fell off and everything went into the floor…so I added a second ring…one on the upper half of plastic lid and one on the lower half of lid. It works perfectly. The original was just one ring….. so idk why it takes 2 of these, but it works.
