O-ring FKM Material Characteristic
FKM (FPM, Viton®, Fluorel®) is often used for its resistance to extreme temperatures and aggressive chemicals. The strong carbon-fluorine bonds that make up the polymer structure have high thermochemical resistance and other excellent properties, such as low compression set at elevated temperatures.
FKM offers excellent resistance to mineral oils and fats, aliphatic, aromatic and some chlorinated hydrocarbons, fuels, silicone oils, and fats. However, FKM exhibits poor resistance to ethers, ketones, esters, and amines.

Temperature Range: -20 to +200°C , temporarily +300°C
has significantly lower mechanical properties in hot water and steam (medium mechanical strength, low gas permeability)
| FKM O-ring is resistant to | temperatures, ozone, weather, aging, acids, mineral, animal and silicone oils and fats, synthetic hydraulic fluids, HFD pressurized fluids, fuels, aromatic hydrocarbons (benzol, toluene), high vacuum, organic solvents, and other chemicals |
| Not resistant to | polar solvents (acetone, etc.), glycol-based brake fluids, superheated steam, ammonia gas, amine alkali, low molecular weight organic acids (formic, acetic) |
