Dimensions: Inner diameter x Outer diameter x Thickness (mm) Fluorocarbon skeleton oil seals are high-performance sealing components composed of fluorocarbon rubber sealing lips and metal skeletons, widely used in harsh conditions such as high temperatures, high pressures, and strong corrosion. Their core advantage lies in the excellent properties of fluorocarbon rubber: a wide temperature range (-20°C to 200°C, with special formulations reaching up to 260°C), resistance to hot oil, fuel, acids, alkalis, and organic solvents, as well as excellent wear resistance and elasticity, ensuring long-term sealing reliability. The metal skeleton provides rigid support, preventing the oil seal from deforming during assembly and operation, and ensuring precise contact between the sealing lip and the shaft. Structurally, it typically includes a main lip, a secondary lip (for dust protection), and a spring. The main lip is tightly pressed against the shaft surface by the spring's preload force, preventing medium leakage. It is commonly used in automotive engines, transmissions, hydraulic systems, and industrial pumps and valves, serving as a critical component in sealing solutions for extreme environments.

• 1.Basic composition: Consists of a fluorine rubber sealing lip and a metal skeleton. The skeleton provides support, while the fluorine rubber provides sealing.
• 2.Material advantages: High temperature resistance (-20°C to 200°C and above), oil and chemical corrosion resistance, and strong anti-aging properties.
• 3.Main function: Prevents oil leakage inside the equipment, blocks external dust and moisture intrusion, and protects components such as shafts and bearings.
• 4.Application scenarios: Mainly used in harsh environments with high temperatures and strong corrosion, such as automobiles, construction machinery, and petrochemical industries.
• 5.Distinctive features: More resistant to extreme conditions than ordinary oil seals (such as nitrile rubber), but more expensive, suitable for high-end or harsh operating conditions.
