Greant 6 PCS O Ring for HydroFlask Wide Mouth Lid, 2'' to 2.3'' Rubber Seal for Hydro Flask Lid, fit Hydroflask Gasket Replacement, 3 Sizes for Different Lids

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!

The HydroFlask thermos we have looks exactly like the blue one in the picture. The new rings fit perfectly.

These were a little loose fitting in my hydroflask compared to the one that originally came with the lid, but when the lid is screwed shut, it does not leak and works as advertised. These are good value for the price.

I bought this for an older Contigo water bottle that was missing the rubber seal. It would leak when I would take sips of water. I measured the opening and realized that it could fit other bottle lids as well. Took a chance and got these seals. Surprisingly, the seal fit and I am able to use my water bottle without having it leak all over the place. Before you try throwing something out because of a leak, I would give these seals a try. It's much cheaper than buying a new bottle and good for the environment.

Does not fit the hydroflask coffee cap as it states. Cap won't close properly. The seal fits in the cap but it appears slightly loose and too thick of a seal

For a wide-mouth water flask. Works perfectly.

The gaskets are not identical to Hydro Flask--those fit snugly in all dimensions and has a 3D profile so that water has to pass through three planes of contact (either through the outside or inside where the lip is). In contrast, these are simple rectangular gaskets that do not reach from side to side, so there is only one point of contact where the lip touches the gasket and in turn presses it against the lid. However, that being said...it appears good enough and doesn't leak when turned--at least the first one I tried.

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.

Perfect fit

Need seal for expensive stainless steel bottle, the seals where the exact size as described.

Fits the Coldest water bottle 32oz wide mouth lid. Good replacement after previous gasket started to have dark molds.

For the price, I decided to try out these gaskets for my Hydroflask wide mouth container. I read reviews saying they were slightly thicker than the factory originals. They indeed are, but not enough to cause issues. The original Hydroflask gaskets lasted a year or so with heavy coffee use and got stained/gunky. These worked for my and I now also have a bunch of spares. Hydroflask are no longer making the flip top lids, so this is a great find for me to extend the lifespan of an otherwise great travel mug. (The included ‘coaster’ is a bit odd.)
