FLUOROSILICONE O-RINGS
Fluorosilicone, commonly abbreviated as FVMQ, is a high-performance elastomer widely used in sealing applications across industries where resistance to fuel, oil, and chemical exposure is critical. Known for its exceptional thermal stability and chemical resistance, fluorosilicone is ideal for environments requiring reliable performance under extreme temperatures and harsh conditions.
With a chemically stable and inert structure, fluorosilicone resists degradation from exposure to fuels, oils, and environmental factors such as ozone and UV radiation. It maintains flexibility and elasticity across a broad temperature range, making it suitable for demanding applications where standard silicone or other materials may fail.
Fluorosilicone is commonly used in industries such as aerospace, automotive, and chemical processing, where its durability and fuel resistance make it a preferred choice for sealing solutions. For optimal performance, fluorosilicone O-rings and seals can be paired with compatible lubricants when needed to enhance sealing efficiency and reduce friction in specific applications.
FEATURES AND SPECIFICATIONS TEMPERATURE RANGE
Standard fluorosilicone O-ring temperature ranges typically extend from -75°F to 400°F, with some specialized formulations capable of withstanding even higher temperatures. These temperature limits are based on dry air, but actual performance may vary depending on the specific application and environmental conditions.
DUROMETER
Standard durometer (hardness) for fluorosilicone O-rings typically ranges from 50 Shore A to 80 Shore A, with 70 Shore A being the most common. This range provides versatility, allowing fluorosilicone to be tailored for specific sealing applications by balancing flexibility for sealing performance with hardness for enhanced durability in demanding environments.
COLOR
Fluorosilicone O-rings are often blue but can also be manufactured in various colors to meet specific application requirements.
