Parker tetrafluoroethylene propylene, TFE/P (Aflas®), o-rings offer superior chemical, heat, and even steam resistance. Aflas o-rings® are typically used in place of FKM (Viton®) to provide better resistance to bases, amines, sour gasses, H2S steam, and radiation. Aflas® o-rings very popular in oil exploration, biotechnology and pharmaceutical industries because of their unique features and benefits. TFE/P compounds carry excellent chemical, heat, and steam resistance. They will provide excellent performance in water, steam, and virtually all caustics, which makes them exceptionally suitable for pharmaceutical and biotechnology facilities requiring a sterilization process using steam and caustic chemicals. TFE/P provides excellent performance in SIP (steam in place), CIP (clean in place) and WFI (water for injection) applications. TFE/P is widely used in the oil exploration and drilling industry due to its excellent steam and H2S resistance. ETS is your AFLAS o-ring supplier!
