HG/T20583-2020 P474 4.4.7 In cases where the medium is ethylene oxide, gaskets made of polytetrafluoroethylene are recommended; for iron-based equipment where the medium is brine or wet chlorine gas, gaskets made of EPDM rubber should be used. What do you think? Can’t PTFE be used as gaskets for saline and wet chlorine?

For this application, EPDM material offers a better sealing performance than PTFE. PTFE gaskets also have their drawbacks.
