Great fit, easy to clean.
Great replacement for water bottles seal. The original seals will get black over time from what could be mold. Yes, these must be removed and sanitized often. After a while the black is just imposible to remove and the seal must be replaced. These fit well and did the job!

If you're careful it works
Not much out there for Hydro Flask gasket replacements (don't know why). It does not have the raised edge of the original, but the silicone is thicker and should offset this problem with a tight squeeze of the lid. The problem is that the measurements are of the outside circumference is a bit smaller than the original. The inside measurement keeps it very tight. So if you slowly and evenly press down it sits well. If you push too far on one side it twists.

Great replacement for THERMOS brand funtainer water bottles
My son managed to lose the gasket from his THERMOS brand funtainer water bottle. You can get replacement straw parts for the funtainer bottles that use those, but I couldn't find replacement gaskets for the pour-style water bottles anywhere (even through THERMOS). After some research, I landed on these. They are slightly thicker than the funtainer ones, but fit the diameter fits perfectly and they make a water-tight seal. Considering how expensive these water bottles can be and how many my kids have, I'm glad to have found an inexpensive solution to prolong their lifespan.

Too thick, still leaks, lid comes off
I am an engineer. This gasket is too thick for the Hydroflask product line - it does not seal. When tightening the lid in an attempt to prevent leaking, it can become over tightened and become completely disconnected, thereby spilling hot liquid on oneself and surroundings. Be very careful if you go ahead and purchase this product. Test carefully before using with hot liquid.

Worked for my non-Hydroflask bottle!
I have a 40oz water bottle (unknown brand) with a lid that requires a 47mm ID 57mm OD gasket. This item worked despite being slightly different dimensions.

Not for hydroflasks
Rubber seals are completely flat and not molded like the original Hydroflask seals.
