Vitron for the win!
Vitron are better where heat is concerned. You get them on glass-cups in TIG set-ups.

Viton are black. Green ones are Nitrile and softer. More often used in aircon units.

Apart from these ones which are green of course.
But then there's this.... which as @wammers says says a specialised Nitrile (often made in Green) is used for temperature resistance, and that is not Viton.

Again from memory, about an inch, but I think that it's open at the back so a slightly longer bolt will not hurt. I coat the stainless bolt in silicone grease in the hope of making removal easier next time.
