Don't know what that one is but we use the high temperature "Teflon Tubing" for this sort of thing all the time (not the heat shrink stuff).
Down side -> this stuff is e-x-p-e-n-s-i-v-e! See Alpha's TFT-200-18 (perfect size for MOV and inrush limiter used on Williams games) at Mouser for an example.
Once you see the price at Mouser, Digikey, others - you'll see why I sell it in 6" lengths.
