Silicone rubber. You can buy silicone hose in a variety of diameters and
in relatively short lengths from eBay. It's widely used by those who
tinker with motor vehicles. It's also handy for replacing fuel hoses on
mowers, chain saws, etc since it is more flexible than PVC, and doesn't
harden.

You might also consider Sugru which (I think) is silicone, but they do
claim an upper temperature limit of 180C.
