BOSORIO 4 Pack Gaskets Compatible with Contigo Snapseal Byron Travel Mug 16oz & 20oz, Replacement Rubber Seal & Silicone Part for Contigo Coffee Travel Tumbler

Worked perfectly for my coffee cups! Perfect fit!

These replacement gaskets fit my Contigo travel mugs perfectly. Easy to install. No more leaks!

I bought these to create a seal on a rechargeable blender, not the advertised product, because they were the right dimensions I needed. I have no idea why with parts like these one cannot just put in the materials and dimensions in a search and have the search pop up with the right size and materials, yet I digress.If your O-ring/gasket isn't sealing, look to see if it is twisted. These are highly malleable and can twist or not seat in the base correctly and thus will not seal and leak. I used some special tools for patting down the gasket into the seal circle and viola, perfect seal, USB portable blender is salvaged. Whatever you use to maneuver and pat down the gasket into place should not have a sharp tip, else the o-ring will be damaged.

Oops - bought these for my wife's Contigo Autoseal (AUTO!) Byron mug. These do NOT work with the Contigo Autoseal Mug as they are too large. If you must depress a button to drink out of your Contigo Mug, these are not for you! Still haven't found a replacement gasket for my wife's mug - sad to say. Gave these gaskets four stars as these are probably fine for Snapseal Mugs :)

Fits perfectly. Saved money on new coffee cup.😊

These are great gaskets and fit my Contigo perfectly. When they started leaking from the lid, I was heartbroken, but now I’m so excited because they are some of my favorite cups and they leak no more!

I love my Contigos, and refuse to throw them away even though they get ugly. After lots of washing and cleaning the seals, they just didn't work anymore. I ordered these to replace the seals and my Contigos work like new again, even if they don't look like it.

These are not made for the Contigo coffee mug I have. Really hoping that the seals would work but sadly not. Seals were slightly too loose and tall for cap to sit flash to the mug close the cap. When unscrew cap to wash mug the seal just loosen and come off. Returning these seals.
