Pack of 3-30 oz Replacement Rubber Lid Ring, Gasket Seals, Lid for Insulated Stainless Steel Tumblers, Cups Vacuum Effect, fit for Brands - Yeti, Ozark Trail, Beast, White Model 2019

This is a true game charger for me and my household. We all use reusable cups and that rubber seal can get kind of nasty after time. I thought for sure I would have to retire my favorite cup until I found you could just re-order the rubber seal. They come in different sizes so just select the size for your cup. Next the shipping with this seller was phenominal. They come 3 to a pack and ease to place onto your lid. The seal and suction is exactly as stated in the description. Honestly, I almost had a time trying to get my lid back off my cup. It's like it was brand new again. Great product. Great Seal. Great Cost. I get to keep my favorite cups in rotation a little longer.

I got these rings to replace the ones that came with my stainless steel 32oz Reduce tumbler from Costco. The rings fit fine around the lid but are very tight when the lid is placed into the cup. The serve the purpose as the cup is leak proof, but sometimes the suction is so strong it is difficult to get the lid back off. The were cheaper than buying a new lid but I won't buy them again for this style of cup.

These gaskets slide onto the lid just fine. But they’re too thick so the lid no longer fits into the tumbler.

When the gaskets arrived they were ribs out, when you install them the ribs should be reversed, if you don't they will leak.

It could have been a bit thicker for a better seal.
