AS568 70 Shore FKM O Rings Sealing Industrial For Fuel / Engine
Systems
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. ORK FKM 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.
