A FEP/PFA encapsulated O-ring seal is a high-performance composite sealing element that features a structure design of 'outer fluoropolymer coating (FEP or PFA) + inner elastomer core'. It combines the advantages of both fluoropolymer materials and the inner elastomer core. Its key feature is its superior chemical resistance; the outer fluoropolymer coating can resist erosion from most chemical media, except for molten alkali metals and certain fluorine compounds. The inner core typically uses materials like fluoroelastomer or silicone rubber, ensuring the O-ring has excellent elasticity and sealing recovery, effectively compensating for gaps in the sealing surface to prevent leakage. This product also has good high-temperature resistance and high cleanliness, with a smooth surface that does not release impurities. Additionally, it is resistant to aging and compression set, offering a long service life.

Composite structure advantages: outer layer of tetrafluoroethylene (FEP/PFA) + inner core elastomer (fluororubber), combining the corrosion resistance of tetrafluoroethylene with the elastic sealing force of the inner core, avoiding the shortcomings of a single material.
Superior chemical resistance: resistant to the erosion of most acids, alkalis, alcohols, ketones, solvents, etc., except for molten alkali metals and some fluorine-containing compounds, suitable for highly corrosive environments.
Wide temperature range adaptability: withstands operating conditions from -60℃ to 280℃, maintaining stable sealing performance at high and low temperatures without risk of brittleness or deformation.
High cleanliness characteristics: the tetrafluoroethylene surface is smooth with no impurities, meeting the stringent cleanliness requirements of the pharmaceutical, food, and semiconductor industries, preventing medium contamination.
Long-lasting durability: strong resistance to aging and compression permanent deformation, reducing the frequency of seal replacement and extending equipment maintenance cycles.
