Blue Color FVMQ Fluorosilicone O Rings
Fluorosilicone O rings are recommended for general purpose service in aerospace and fuel applications, and provide good high, low temperature
performance in sealing fuels and mineral oils. Fluorosilicone rubber is a widely used elastomer that can be compounded to meet a wide range of
applications. The mechanical and physical properties are very similar to silicone rubber. However, fluorosilicone offers improved fuels and mineral
oil resistance but poor hot air resistance when compared with silicone.
Advantages
• Improved fuel & mineral oil resistance than silicon
• Excellent resistance to aging & weather-sunlight
• Resistant to oxidizing chemicals, fules
• Resistant to animal & vegetable oils
• Good heat & ozone resistance
• Good chemical resistance
Application
• Petroleum oils & hydrocarbon fuels enviroment
• Jet fuel and dry heat enviroment
• High or low temperature usage
• Most chemical enviroment
• Chlorinated Solvent., etc
