Professional O-Ring and Oil Seal Manufacturer, Sealing Solution Supplier Since 2008.
FVMQ Fluorosilicone O-Rings – Exceptional Sealing Performance for Demanding Environments
Engineered with Fluorosilicone (FVMQ) for Superior Resistance to Heat, Oil, and Harsh Chemicals
Our FVMQ fluorosilicone O-rings are precision-engineered sealing components designed to excel in challenging environments. Made from fluorosilicone (FVMQ), they combine the thermal stability of silicone with the chemical resistance of fluoropolymers. These O-rings offer outstanding resistance to high temperatures, oils, fuels, solvents, and a wide range of harsh chemicals. Their robust construction ensures reliable sealing performance, durability, and longevity, making them indispensable for critical applications in automotive, aerospace, industrial machinery, and other sectors where stringent sealing requirements and exposure to extreme conditions are the norm.

Product Advantages
Forever Seals’ FVMQ fluorosilicone O-rings stand out with unmatched thermal stability (operating range: -55°C to 200°C) and superior resistance to oils, fuels, solvents, and harsh chemicals. They combine silicone’s flexibility with fluoropolymer’s durability, ensuring long-lasting sealing performance without deformation. The material’s low compression set and excellent weatherability reduce maintenance frequency, delivering cost-effective reliability for critical systems.
Working Principle
These O-rings create a secure, leak-tight seal by leveraging radial compression between mating surfaces. When installed in grooves, the FVMQ material’s inherent elasticity exerts continuous pressure against contact points, blocking the passage of fluids, gases, or contaminants. The fluorosilicone composition maintains structural integrity even under extreme temperatures or chemical exposure, ensuring consistent sealing efficiency in dynamic or static applications.
