Product Description
FEP Tetrafluoro Silicone Rubber Fluororubber Coated O-ring & Gasket
Ultimate Chemical & Abrasion Resistance
Dual-Material Innovation • Superior Sealing Performance • For Extreme Environments
Product Overview
A FEP/PFA encapsulated O-ring seal is a high-performance composite sealing element featuring an innovative 'outer fluoropolymer coating (FEP or PFA) + inner elastomer core' structure. This design combines the superior properties of both fluoropolymer materials and the inner elastomer core, delivering exceptional performance in demanding applications.
The key advantage lies in superior chemical resistance; the outer fluoropolymer coating resists 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 excellent elasticity and sealing recovery that effectively compensates for gaps in sealing surfaces to prevent leakage.
This product offers excellent high-temperature resistance and high cleanliness, with a smooth surface that does not release impurities. Additionally, it provides strong resistance to aging and compression set, ensuring a long service life.
Key Features & Benefits
- Dual-Layer Protection: Silicone/FKM core for elasticity + FEP coating for chemical resistance
- Chemical Inertness: Resists 1,800+ chemicals, including acids, solvents, and plasmas
- Wide Temperature Range: Performs from -60°C to +280°C (short-term to +230°C)
- Zero Permeability: FEP coating prevents gas/liquid permeation, ensuring long-term sealing
- Non-Stick Surface: Prevents adhesion of sticky media and simplifies cleaning
