Encapsulated O rings, also known as "fluorinated O rings" and "Silicon-coated O rings" also have "Double-layered O rings".The external use of FEP or PFA special high temperature resistant fluoroplastic, and internal coated elastic rubber (fluorine rubber/silicone, etc.) Besides, O rings coated with FEP or PFA have good resistance to swelling and chemical stability (unless they are attacked by alkali metals, fluorine, and some halogens at high temperatures) and have good elasticity near the rubber O rings.
FEP-encapsulated O-Rings (Fluorinated Ethylene Propylene):
* Outstanding chemical and corrosion resistance
* Low coefficient of friction
* Resilience with choice of elastomeric cores
* Low compression set
* No mould charge
* Solid silicone, Viton cores
PFA-encapsulated O-Rings (Perfluoroalkoxy). Same as FEP above but with these added benefits:
* Higher mechanical strength
* Better flex-life
* Low vapor permeation
* Excellent stress and crack resistance
* Longer wearability
* Solid silicone & Viton core
