I can't seem to source any Teflon O-rings.
I've had Vitron suggested to me.
22mm id 2mm thickness
Viton® withstands high temperature and simultaneously retains its good mechanical properties better than most other elastomers. Oil and chemical resistance also are relatively unaffected by elevated temperatures. Compounds of Viton® remain usefully elastic indefinitely when exposed to laboratory air oven aging up to 204°C (400°F) or to intermittent test exposures up to 260°C (500°F). High temperature service limits are generally considered to be:
3,000 hr. at 232°C (450°F)
1,000 hr. at 260°C (500°F)
240 hr. at 288°C (550°F)
48 hr. at 316°C (600°F)
What do you think, could I use these for my system?
