Can silicone rubber soft-sealed valves be used for ethylene glycol solutions at temperatures ranging from minus 50 degrees to 60 degrees??:handshake

No! Due to the properties of the material itself, ordinary rubber generally cannot be used at temperatures below -50 degrees! Modified polytetrafluoroethylene (PTFE) can be used. Theoretically, PTFE can be used down to –196 degrees. :)
