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?
