Blue-Colored FVMQ Fluorosilicone O-Rings
Model:KXT 1710FVMQ
Blue Color FVMQ 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.

Frequently Asked Questions About FVMQ Fluorosilicone O Rings
- Q: What is FVMQ fluorosilicone rubber and how does it differ from standard silicone?
- A: FVMQ (fluorosilicone) is a type of silicone rubber that has been modified with fluorine atoms to improve resistance to fuels, oils, and solvents. While it retains silicone's excellent low-temperature flexibility and wide temperature range, it offers significantly better resistance to petroleum-based fluids compared to standard silicone (VMQ). It is the material of choice for aerospace and automotive fuel systems where both fuel resistance and low-temperature performance are required.
- Q: What is the temperature range for FVMQ O-rings?
- A: Standard FVMQ O-rings are rated for continuous service from -65°C to +175°C. They maintain excellent flexibility at very low temperatures, making them suitable for aerospace and cryogenic applications.
- Q: What chemicals is FVMQ resistant to?
- A: FVMQ offers excellent resistance to petroleum oils, jet fuel, gasoline, diesel, mineral oils, synthetic lubricants, and many chlorinated solvents. It has good resistance to acids and alkalis, but limited resistance to hot air and steam compared to silicone. It is not recommended for use with strong oxidizers or high-temperature steam.
- Q: Why are FVMQ O-rings blue in color?
- A: The blue color is a standard industry identification for fluorosilicone materials, helping to visually distinguish FVMQ from other elastomers (e.g., black for nitrile, green for Viton). This prevents material mix-ups in assembly and maintenance environments. Custom colors are available upon request.
- Q: What sizes and hardness grades are available?
- A: We manufacture FVMQ O-rings in all AS568 standard sizes, metric sizes, and custom dimensions. Hardness grades range from 40 to 80 Shore A, with 70 Shore A being standard. Contact us with your size and hardness requirements for a custom quote.
