Food grade gaskets?

climberdude · March 24, 2020, 2:30am

Hi there, with all this time at home I have been trying to tidy up and fix up some things that have been lying around for a while.

I have a nice vacuum flask for which I lost the gasket that was in the lid. Does anybody know of a relatively cheap source for a food-grade gasket that can hold hot liquids? it’s a flat one for sealing against a sharp edge and I think it’s ~1.75" diameter. Any ideas?

Thanks a lot!

Try looking for silicone gaskets for canning supplies. Like this Amazon.com

Edit: although these might be too big

Thanks, but they do look a little too large.

Buy some silicone sheet and use an exacto knife to cut one out?
