High Temperature Sealant?

I am going to need some high temperature sealant where the exhaust line for my cookstove penetrates the floor of the van. I will be wrapping the exhaust line with a heat shielding exhaust tape which will block most of the heat, but in the interest of prudence, I want to use a high temperature sealant for this application.

Any suggestions?

Any Home Depot/Lowe's type place is going to have fire block sealant for sealing cracks around chimneys. It comes in a caulk cartridge tube. I've seen it used on Propex exhaust installs through the floor.

My floor penetrations for the propex exhaust are rubber fine.....the ducts don't get that hot........don't know the specifics of your cook stove...
