Florocarbon Coloured FKM O Rings 70 For Automotive Fuel Handling Systems
ASTM D1418 Designation: FKM
ORK Compound Designation: VT
Standard Color: Yellow
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.
