Temperature: -20 - +200℃
Material: FEP encapsulated FKM
FKM core – FKM (black) features very good rubber-elastic qualities. FKM has the capacity to re-assume its original form after its deformation thanks to its outstanding compression
Silicone core – The silicone core (mostly red) is considerably softer than an FKM core. In turn, it is more temperatureresistant. In addition to its superb thermal resistance, it has very good cold flexibility.
FEP encapsulation – FEP (fluorinated ethylene propylene) gives an O-ring its tremendous characteristics relating to its resistance to nearly all liquids, gases and chemicals. The exceptions are liquid alkali metals and some fluorine compounds.
PFA encapsulation – Perfluoroalkoxy copolymer (PFA) resembles FEP in its areas of application. It is distinguished by improved cold flow properties and optimized mechanical
qualities at higher temperatures.
