Material
FPM / FKM (fluoroelastomer, Viton®)
- Operating temperature-20 °C to +200 °C
Good for high temperature, all fuels and oils, ozone and sunlight. Not for brake fluid, acetone-type solvents, ammonia, hot steam or severe cold.
| Can be used | Do not use |
|---|---|
| High temperatures, continuously up to +200 °C | Acetone, MEK, dioxane, ethyl acetate and similar solvents |
| Mineral and synthetic oils, incl. engine oil and oils with aggressive additives | Brake fluid (DOT 3, DOT 4, DOT 5.1): the ring swells |
| Benzene, toluene, xylene, trichloroethylene (aromatic and chlorinated solvents) | Ammonia, amines and alkaline liquids: the rubber breaks down |
| All fuels: petrol also with bioethanol (E10, E85), diesel, biodiesel, aviation petrol | Steam and hot water above +120 to +130 °C |
| Fire-resistant hydraulic fluid HFD-R (phosphate esters) | Formic acid and strong acetic acid (low-molecular organic acids) |
| Ozone, UV and sunlight (hardly any ageing) | Severe cold below -20 °C with standard FPM: it hardens and leaks |
| Deep vacuum (very little outgassing) | Hot fluorine gas and hydrofluoric acid (HF) |
Safety: if the seal is heated above +300 °C (fire, gas torch), FPM releases toxic hydrogen fluoride. Do not touch the burnt residue with bare hands: it forms hydrofluoric acid and causes chemical burns.
