    High Pressure Encapsulated O-Rings FKM For Oxygenated Automobile Fuels
    FKM® is the trade name for DuPont-Dow Elastomers Fluorocarbon or FKM material. FKM® has a temperature range of -20F to +400F, and provides excellent resistance to a wide variety of chemicals, weather and conform to FDA requirements, making it ideal for use with foods and medical devices.. The relatively high level of fluorine in FKM® materials allows for exceptional resistance to chemical attack, but with limited low temperature capabilities. Intermittent exposure to +600F can be tolerated for brief periods of time
    FKM® O-rings have established new performance standards in advanced fuel and engine systems, and provide improved system reliability for extreme temperatures for fuels, oils, transmission fluids and acid condensates. FKM® orings can help extend maintenance intervals and protect against seal failure.  Low temperature resistance is not preferred in static applications for traditional FKM® o-rings , and is limited to approximately -15°F (-26°C). When used in dynamic applications, the low temperature is between 5°F and 0°F (-15°C and -18°C). Gas permeability is low and similar to butyl rubber.
    ASTM D1418 Designation: FKM
    ASTM D2000/SAE Type, Class: HK
    ORK Compound Designation: VT
    Standard Color: Black
    Description: Combining high temperature resistance with outstanding chemical resistance, Fluorocarbon-based compounds approach the ideal for a universal O-ring material.
    Key Use(s): Seals for aircraft engines. Seals for automotive fuel handling systems. High temperature/low compression set applications. Wide chemical exposure situations. Hard vacuum service.
    Temperature Range
    Standard Compound: -13° to +446°F
    Special Compound: -40° to +446°F
    Hardness (Shore A): 55 to 90.
    Features: High fluorine grades offer higher resistance to swell in high octane and oxygenated fuel blends. This give superior performance in Ethanol/Methanol blended gasoline. Base resistant grades offer improved resistance to amine based oil protectants found in new transmission oils.  Also, improved resistant to steam for higher temperature services. Low temperature bases can improve performance to -40°F.
    New Polymers being offered have improved chemical resistance and low temperature performance.
    FKM® Extreme™ ETP offers similar chemical compatibility as Kalrez™ with temperature performance with a TR(10) of -40°F and brittleness to -76°.
    Limitations: Fluorocarbons (FKM®s) are not recommended for exposure to ketones, amines, low molecular weight esters and ethers, nitro hydrocarbons, hot hydrofluoric or chlorosulfonic acids, or Skydrol® fluids. They are also not recommended for situations requiring good low temperature flexibility.
