2 Pack Replacement Rubber Gasket Seal Ring 30 oz Tumbler Vacuum Stainless Steel Cup Flex Spare Fits Yeti Fits Ozark Trail Fits Rocky Mountain Top Lid CocoStraw Brand (2 Pack Gaskets - 30oz)

I ordered a set of replacement gaskets for both of my 30oz tumblers. One is a Yeti, the other is an Ozark Trail. I've have both for quite awhile, and I had started to notice that the Yeti gasket wasn't keeping the lid on as well as it did when it was new. I ordered this gasket set, and figured I'd switch out both - although there was nothing wrong with the gasket in my go-to, live-in-the-Jeep Ozark Trail tumbler that I probalby use more than the Yeti. The gaskets arrived when promised, and the quality was very good - no obvious cut marks, blemishes, or defects in workmanship. The gaskets were both round (I've seen some reviews where the gaskets weren't shipped or packed flat), flat and exactly as promised when ordered. They were easy to install as well; you simply remove the old gasket make sure this one is facing the same way, and slip it on. Easy, peasy! The one thing I did find out - which was somewhat disconcerting - is that no matter how clean you THINK you're cleaning your tumbler lid, there is gunk, goo, and general nastiness in that divot where the gasket lives. I have religiously cleaned with hot water and the appropriate soap the tumblers and their lids after every use - at least once a day. I wouldn't say I'm a 'clean freak' but I do like to keep my equipment in good and serviceable condition at all times ... you never know when there may be a coffee emergency that requires and immediate evac of 30 ounces of delicious hot beverage from a coffee shop. And let me tell you: whatever that stuff was, it was nasty. So a good safety tip is to make sure you remove that gasket and clean under it every now and then. It might shoten the life of the gasket by a bit, but cleanliness is next to Godliness, right? Absolutely THRILLED with the gaskets, the do fit the Yeti ($30) and Ozark Trail ($9) 30oz. lids, and they both work fabulously. Good investment!!!

My old one was getting moldy and really REALLY gross. Yeti tumblers are expensive and this saved mine! I took away only star (I'd only do a half if I could) because they feel ever so slightly loose, so that if you push the lid down even slightly crooked, it pops out in a weird way. This could be because my mug is older, maybe the newer ones are slightly bigger? But it's a super easy fix to just pop it off and try again. Worth the price for sure!

After a while, as we all know these gaskets get moldy and gross. I am so glad I found these as a replacement! Affordable with a great seal! Now my husband's tumbler is like new! Works with all of our 30 oz tumblers which is a plus instead of having to purchase a whole new tumbler because who has the money to do that!

Fits my Yeti 30 oz tumbler well. I find using a butter knife aids in flipping out gasket. Yes, you should be removing gasket on a regular basis to clean out tumbler parts. Mold and bacteria are always growing! Soap and water and a brush to the gasket, top and cup. When you notice little black rubber particles when cleaning and when it becomes harder to form a good seal when drinking, it's time to change gasket. Mine lasted about 2 years per gasket.

Works like a charm as long as you put it on right! LOL I have had a Yeti aluminum tumbler for approximately 8 years. I have had ice in it when I go to bed and there will still be ice in it when I wake up! Well the gasket finally quit on me. I would be lucky if the ice lasted half a day! I ordered these ring replacements and kept my fingers crossed! Put it on and the first couple of days I wasn't very happy...so I thought "hmmm.. Could I have it on wrong?" So I took it off and turned it inside out and put it back on and WAH LAH! works great! Seemed a little pricey at $5 plus dollars for 2, but hey! If it lasts another 8 years I am more than happy with this purchase!!

Gasket is not tight enough for the lid. After short period of use does not stay in place after removing lid from cup.

Our original gaskets for our tumblers were disintegrating and my husband said “ugh I wish I could just get replacements”. Little did he know Amazon comes in handy for stuff like that! These fit perfectly into our Yeti and Ozark lids. They came super fast and price was great! Super easy to pop into our existing lids. Much better than replacing the entire cup!

They worked as described just what I needed for mug

Fit my Rocky mountain tumbler but seemed looser than the original gaskets. No leaks so far and the lid isn't loose at all.

We'll happily buy this product again when needed.

These do not work as Yeti replacement gaskets, they are very tiny, leaks

Not oem but fit just perfect on My yeti

Like others have said. they are way undersized. definetly not ment for Yeti Large Lids. most likely ment for the medium lids
