Professional O-Ring and Oil Seal Manufacturer, Sealing Solution Supplier Since 2008.
FEP Encapsulated FKM Composite Elastic O-Ring Seal
High Temperature Corrosion Resistant Double Layer Combined Sealing Ring
This composite sealing ring makes up for the performance defects of single material O-rings. FEP outer layer isolates harsh chemical media to avoid material swelling and erosion, while the elastic FKM inner core provides stable compression resilience to adapt to assembly gaps and mechanical vibration. It solves common failures such as seal aging, medium corrosion and elastic failure, and serves as high-reliability sealing parts for high-standard hydraulic, chemical and high-temperature equipment.

1. Product Advantages
The dual-material composite structure endows the O-ring with strong comprehensive performance, the outer FEP layer resists strong acid, alkali and various organic solvents effectively without being corroded and deformed, and the built-in FKM rubber core delivers good elastic recovery and high temperature resistance to keep stable sealing state under long-time working condition. The whole ring features compact structure, stable size and good fitting performance, which can adapt to frequent pressure changes and slight vibration, effectively prolong service life and reduce the frequency of equipment maintenance and parts replacement.
2.Installation Recommendation
3. Working Principle
After being installed inside the sealing groove, the composite O-ring is squeezed by matching parts to produce elastic compression deformation. The outer FEP layer contacts and isolates flowing medium to prevent chemical erosion, while the inner rubber core provides lasting elastic supporting force to fill assembly gaps completely. It can block internal medium leakage and prevent external harmful substances from entering equipment interior, realizing stable and durable sealing isolation effect.
4. Product Details
The product is made by professional integral encapsulation molding technology, with tight combination between FEP outer skin and FKM inner core without peeling off. The surface is smooth and uniform, free of cracks, bubbles and deformation flaws, with accurate overall dimension and stable hardness. All finished products pass strict performance and appearance inspection, and are stored and delivered with dustproof and moistureproof independent packaging.
5. Application Range
Widely used in high temperature hydraulic systems, chemical fluid pipelines, precision mechanical fittings and corrosion-resistant industrial equipment. It is applicable to sealing scenes with diverse corrosive media, high working temperature and strict sealing requirements.
6. FAQ
Q1: What are the advantages of FEP+FKM composite structure?
A1: It takes both corrosion resistance and high elasticity into account, overcoming the weakness of single material and adapting to more harsh working conditions.
