Chemical Resistant Fluorocarbon FKM O-Rings have an excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals. FKM has a temperature range of -20F to +400F, and provides excellent resistance to a wide variety of chemicals, weather and compression set requirements. The relatively high level of fluorine in Fluorocarbon FKM materials allows for exceptional resistance to chemical attack, but with limited low temperature capabilities.
Chemical Resistance:
Mineral oil and grease, low swelling in ASTM oil No. 1, and IRM 902 and IRM 903 oils
