Fluorosilicone O-Ring is a high-performance seal that combines the properties of fluoroelastomer and silicone rubber. It is made of fluorosilicone rubber (FVMQ), a material that is a copolymer of fluoroelastomer and silicone rubber, and thus inherits the advantages of both. Below are some detailed descriptions of Fluorosilicone O-Rings:

What is the FVMQ O-rings Material Properties ?

• High temperature resistance：Fluorosilicone rubber has good high temperature resistance and can usually be used in the temperature range of -60°C to +200°C, which makes it still maintain good elasticity and sealing performance in high temperature environments.
• Chemical resistance：Fluorosilicone rubber has good resistance to some chemicals, especially to oils, fuels and some organic solvents.
• Electrical insulation properties：Fluorosilicone rubber has good electrical insulation properties, suitable for sealing electrical and electronic equipment.
• Weathering and aging resistance：Fluorosilicone rubber has good weathering and aging resistance, and can maintain its performance in outdoor and long-term use conditions.

Which are the FVMQ O-rings Application areas ?

• Automotive：In automotive engines and transmission systems for sealing oil, fuel and coolant.
• Aerospace：In aerospace equipment, for sealing hydraulic systems and fuel systems.
• Electronics industry：In electronic equipment and circuit boards, to seal and protect electrical connections.
• Industrial equipment：in a wide range of industrial machinery and equipment for sealing lubricants and chemicals.

What should we pay attention to ?

Fluorosilicone rubber typically costs more than regular silicone rubber, but less than perfluoroether rubber, so fluorosilicone O-rings are priced somewhere in between.

What of the FVMQ O-rings Specifications and Standards ?

• Colors: Blue, Black
• Temp：-60℃ – 200℃
• Hardness range: 30~90 Shore A
• Processing technology: molding
• Standard: GB/T3452.1-2005, AS-568, DIN 3771, JIS B2401, ISO 3601-1
