Genuine Chemours Viton® washers are made from FKM (fluoroelastomer) rubber making them the ultimate solution for sealing in demanding conditions.
What makes the Viton washers superior?
Chemical resistance
Due to high fluorine content, fluoroelastomer provides resistance to acids, oils, fuels and solvents, as well as ozone, fungus and mould.
Temperature tolerance
FKM rubber can withstand temperatures ranging from -29°C to 200°C.
Compression resistance
The material will return to its original shape after lengthy periods of compression, even under high and low temperatures.
Tear resistance
Its tear resistance of 20kg/cm makes it suitable for environments where sharp edges and rough surfaces are present.
Durability
Made out of very strong material, genuine Chemours Viton® washers offer longevity and will help reduce downtime and maintenance costs.
Commonly used in automotive, aerospace, chemical processing, marine and oil & gas industries, it’s use ranges from sealants in pipelines and fuel tanks, to combustion chambers and turbine sections.
