does this fit the old style wide mouth hydroflask 32 and 40 oz?

Hello, Miguel from Tall Ridge here! Yes, this is designed to fit both the newer versions as well as the older generations of wide-mouth bottles. I hope you find this helpful.

Does it fit a 32 ounce?

Caps are universal. Standard and wide mouth is all you need to know. So, yes it will indeed fit a 32 oz.

Would this lid fit on a 40oz wide mouth Hydroflask water bottle?

It does,but you should be aware it's a tight fit. I put mine on a 32oz wide mouth bottle and it seals tight and does not leak when knocked over or held upside down. But putting the lid on and taking it off can be difficult.
