It was a rubber door strip like this
It would probably be okay. I'm having a bit of a hard time understanding what you are wanting to do with it. Are you going to cut a hole in the cooler for the sous vide machine and are wanting to create a seal around that whole? The rest of the cooler should already be well insulated, including the hinges area.
Anyway, I would probably use something like this Weather Striping it has good insulation properties and will compress and create a good seal. The temperature range might be a bit of a problem on higher heat longer cooks. I've never used it in a sous vide project, but I've used this sort of foam tape in a lot of other DIY projects and my experience is that it will soften at the higher temps but won't melt unless it gets really hot.
