FEP | PFA Encapsulated O-Rings with silicone | FKM
Encapsulated O-ring with rubber O-ring as the inner core and FEP / PFA tube as the outer layer. FEP / PFA encapsulated o rings has the characteristics of heat resistance, cold resistance, oil resistance, wear resistance, climate aging resistance and chemical medium corrosion resistance. It can be used in various dynamic and static sealing occasions and can replace some traditional sealing rubber O-rings and expensive perfluoroether O-rings.
