Chemical Resistant Fluorocarbon FKM O-Rings 75/80 Durometer:

Chemical Resistant Fluorocarbon FKM O-Rings:, has excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals. Fluorocarbon 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. Fluorocarbon FKM is quickly becoming the go to Oring in many applications.
