Applications of Fluorosilicone Seals in Automotive Fuel Systems, Aerospace, and Hydraulic SystemsFluorosilicone seals, with their unique resistance to high and low temperatures, oils, solvents, and chemical stability, play an irreplaceable role in automotive fuel systems, aerospace, and hydraulic systems. Specific applications are as follows:
  
1. Automotive Fuel Systems
Fuel Pipe Seals
Used in fuel pipe joints, fuel pump diaphragms, and other areas, they withstand long-term corrosion from gasoline, diesel, and methanol-containing fuels, preventing fuel leaks.
Fuel Tank System Seals
Fluorosilicone is used in fuel tank cap gaskets and fuel filler rings to ensure volatile oil vapor isolation and reliable sealing.
Critical Engine Components
Suitable for high-temperature and high-pressure environments such as turbocharger seals and exhaust system seals, improving fuel economy and safety.
  
2. Aerospace
Fuel and Hydraulic Systems
Components such as aircraft fuel tank seals and hydraulic line bellows must withstand aviation fuel, hydraulic oil, and extreme temperatures (-50°C to 250°C). Fluorosilicone provides long-term, stable performance. Engine Seals
  
Used for dynamic seals in high-temperature engine areas, resistant to jet fuel corrosion and maintaining elasticity at high temperatures.
Avionics Protection
Seals cockpit instruments, sensors, and other electronic components, providing both insulation and radiation resistance.

️3. Hydraulic System
Hydraulic Cylinder Seals
Using nano-filling technology (such as carbon fiber/bronze powder) to reduce the friction coefficient (to 0.02), reduce energy consumption, and improve high-pressure extrusion resistance.

Valve and Pipe Seals
Used for hydraulic control valves, high-pressure oil pipe joints, and other applications, resistant to corrosion by mineral oils, ester hydraulic fluids, and chemical media.
Extreme Operating Conditions
Replaces perfluoroelastomer in oil drilling equipment (such as submersible electric pumps), reducing costs and extending seal life.

Core Performance Advantages
Temperature Adaptability: Long-term temperature resistance from -68°C to 232°C, short-term resistance to 250°C.
Chemical Stability: Resistant to fuel oils, engine oils, aromatic hydrocarbons, and acids and alkalis. Mechanical properties: low compression set, high resilience, suitable for dynamic sealing scenarios.
