2 Pack New OEM Replacement Rubber Lid Seals for 14 or 30 Ounce Insulated Stainless Steel Tumbler Lids Such As Yeti RTIC Ozark Trail Mossy Oak Atlin Beast

Fits the Yeti 30oz Rambler perfectly! It took a little adjustment, because it twisted when I put it on the lid, and I had to take it off and check to see which way it went on, but once I got it on there, it fit perfectly. My original seal gave up after about 6 months, and I poured water all down my front while taking a sip. I was pretty irritated, because that's a lot of money for a cup with a lid, only to have the lid fail after such a short period of time. I thought I was going to have to give up on it, then thought to search Amazon. I am not disappointed! Other reviews say it didn't fit their Yeti, I'm wondering if they were trying to use it on a smaller cup, or if they didn't get the seal on the lid correctly, because it works great on mine. UPDATE 27 January 2019: I ordered two more as spares, but got a completely different seal. The original ones were oval in shape, and the exact size to fit the Yeti 30oz Rambler. These are very small, and round, and they look far too small for the big Yeti. HOWEVER, much to my delight, they fit perfectly!

These fit my Yeti 14 oz coffee cup perfectly.

Works perfectly.

Purchased as a replacement for the rings on my 30oz Yeti Rambler. Easy to remove and replace but these new ones are slightly different. They have deeper ridges which make installing and removing the lid a bit more difficult. Comparing the original with one of the new ones you can see the difference. I expect the durability to be the same and haven't noticed any leakage. After almost 9-years my Yeti is still going strong.

Good product. No issues.

I bought these to replace the original rings for my Sam's Club 30 oz. insulated tumblers. They fit fine but when I was trying to push the lid down on the cup, it was a little tight. It's better with it being tight than loose. There is no spill with I lay the tumbler sideways.

I have a 14oz RTIC tumbler whose seal is finally starting to go bad. It's gotten to a point where, while driving, I worry with each sip of coffee that the lid's gonna pop off and pour STEAMING HOT CAFFEINE ALL OVER MY LAP AND NETHER REGIONS! So to remedy that I just bought a IIIA soft plate and put it on my lap wherever I drove. It was only a pound and didn't really deter me from driving, but after getting caught speeding by the cops and having to deal with explaining why I had body armor on my crotch, I decided maybe I should just get a new seal. This one was not the one I should have gotten. It was a two pack, so I figured, I'll have one for whenever this first one fails. It's not from RTIC so I don't really know when it will, but at least it's just six bucks. Ordered, shipped, waited for it to arrive, got snowed in, finally got it. And it looks like an adequate seal. The only problem, and it's sort of a main problem, is that it doesn't even fit. It's got more stretch out of the baggie than my current, five-year-old seal has, and that one still fits tighter than the tighty whiteys my wife says don't fit me anymore because I'm like thirty pounds heavier than when she married me. By the way, she's right I get it now. Anyway, This thing just isn't for me. Even after following the instructions, I just can't get the darned thing to fit on my lid. I can't ... I can't make it smaller. The thing is big and proud and just wants to show off. Unfortunately, it's just a little too much for me.

This replacement seal was a perfect fit for my cold travel mug. While I did not had a Yeti brand cup, it was nearly identical. It has a square cross section with a gap between the middle to give two sealing surfaces. I at first struggled to get the replacement seal on my mugs lid. I ended up running HOT water on it with some dish soap as lubrication and then it slipped into the grove in the mugs lid. The original one got a musty, or moldy smell to it that I could not get rid of. Thankfully these fit and seal perfectly
