O-Ring Materials
FKM | Viton®
One of the most advanced and resistant materials for O-Rings: FKM, also known as fluoroelastomer or Viton® (its best known commercial name).
What is FKM?
FKM is a synthetic elastomer that stands out for its exceptional resistance to extreme conditions.
It is especially valued in industries that demand high performance and durability.
Advantages of FKM
FKM, also known as fluoroelastomer, is a high-end material widely used in O-rings because of its exceptional strength properties. Its main advantage lies in its ability to withstand extreme temperatures, both high and low, as well as its outstanding resistance to aggressive chemicals such as acids, bases and solvents.
This makes it the ideal choice for applications in industries such as automotive, aerospace and petrochemical. FKM also stands out for its durability and reliability, offering effective sealing and long service life, which reduces the need for maintenance and improves system efficiency.
Chemical Resistance:
FKM offers outstanding resistance to a wide variety of chemicals, including oils, fuels, solvents and strong acids.
High temperature resistance:
It performs optimally in a temperature range from -25°C to 230° (even up to 265°C for short periods), making it ideal for high temperature applications.
Durability:
It has excellent resistance to aging, ozone and weathering, ensuring a long service life in exposed applications.
Low permeability:
It has low permeability to gases and liquids, which makes it an excellent material for applications requiring hermetic sealing.
Common FKM Applications
Automotive:
Components in engines, transmissions and fuel systems.
Aerospace:
Seals and gaskets in engines and fuel systems.
Chemist:
Chemical processing and storage equipment.
Oil and Gas:
Seals on pumps, valves and other equipment in extreme conditions.
Limitations:
FKM is a premium material, but its performance can be compromised in low temperature environments below its optimum range.
