Industrial Fluorine Rubber O Ring Seals , Fluorocarbon Oring TS16949 ROHS
FKM O-RINGS:
FKM® O-rings from ORK offer excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals making it excellent for o-ring, gasket and seal materials. ORKFKM o-rings (FKM o-rings, fluorocarbon rubber o-rings) provide excellent permeability and compression set resistance.
FKM® O-rings (FKM o-rings) have low gas permeability and FKM o-rings (FKM o-rings) are commonly used as gaskets in fuel system sealing applications. Other fluorocarbon compounds can also offer improved resistance to acids, fuels, water and steam.
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 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.
