Description

Sealing of the shaft of agricultural machinery JOHN DEERE.

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.

Chemical resistance
Can be usedDo not use
High temperatures, continuously up to +200 °CAcetone, MEK, dioxane, ethyl acetate and similar solvents
Mineral and synthetic oils, incl. engine oil and oils with aggressive additivesBrake 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 petrolSteam 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.
