   • Material: FKM for high-temperature endurance (200–250°C).
5. Power Steering Oil Seal
   • Design: Low-friction PTFE or FKM ensures reliability in high-speed steering systems.

Specialized Seals

• Vition Oil Seal (FKM): Resists temperatures up to 250°C and chemical corrosion, ideal for aerospace and chemical industries.
• Combination Gasket: Multi-layer static sealing solution for extreme temperature fluctuations.
• Hub Oil Seal: Dual-lip design for dust/waterproofing in trucks and construction machinery.

O-Rings and Accessories

• Viton O-Ring: Fuel and chemical-resistant for high-temperature environments.
• Silicone O-Ring: Bio-compatible and low-temperature tolerant (-50°C), suitable for medical and food-grade applications.
• NBR/EPDM O-Ring: Cost-effective solutions for oil-based or aqueous media.

Feiyun’s Competitive Advantages

• Material Science: Utilizes FKM, PTFE, NBR, and silicone to cover extreme conditions (-50°C to 300°C).
