fluorocarbon rubber seal ring
Trade Names:
Viton® . . . DuPont Performance Elastomers
Fluorel . . . 3M Company
Technoflon . . . Solvey Solexis, USA
ASTM D1418 Designation: FKM
ASTM D2000/SAE Type, Class: HK
Apple 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.
Viton® Extreme™ ETP offers similar chemical compatibility as Kalrez™ with temperature performance with a TR(10) of -40°F and brittleness to -76°.
Limitations: Fluorocarbons (Viton®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.

| Common Name | FKM, FPM, FFKM |
| Chemical Name | Fluoro Rubber |
| Trade Names | VITON® (registered trademark of the DuPont Dow Elastomers)
FLUOREL® (registered trademark of the 3M Company) |
| General | FKM is a M Class Rubber
Contains a saturated chain of the polymethylene type
Fluoro rubber of the polymethylene type having substituent fluoro and perfluoroalkyl groups on the polymer chain
Fluorocarbon elastomers are inherently compatible with a broad spectrum of chemicals. Because of this extensive chemical compatibility, which spans considerable concentration and temperature ranges, fluorocarbons have gained wide acceptance as a material of construction for butterfly valve o-rings and seats.
Excellent resistance to mineral acids, salts solutions, oils and many aliphatic and aromatic hydrocarbons.
Attacked by caustic (sodium hydroxide) and low molecular weight organics.
There are several different grades of material available. Care should be taken in selecting the right grade for the application. |
