Discover the properties of our FFKM seals

FFKM joints are the solution when FKM has shown its limitations.

FFKM O-ring seal, or perfluoroelastomer, is a rubber that contains more fluorine (72.50%) than standard FKM (66%), enabling it to reach higher temperatures and greatly improving its resistance to aggressive fluids.

Special applications

Aerospace

FFKM perfluorinated O-rings are widely used in the aerospace industry for their resistance to the most extreme conditions, such as high pressure, ignition circuits and high resistance to degradation.

Chemical processing

FFKM is used in the manufacture of O-ring seals, suitable for high-temperature environments or those exposed to aggressive chemicals used in the oil industry.

Food and beverages

ULTIMA® materials offer proven high sealing performance and are suitable for CIP and SIP processes used in the food industry.

Oil and gas

FFKM seals are the best choice for withstanding high pressures and temperatures, while offering excellent resistance to corrosion caused by chemical reagents.

Medicines

FFKM, renowned for its exceptional chemical stability, heat resistance and anti-aging properties, is establishing itself as a key material in the medical field. It is able to withstand a wide range of chemical substances, and offers excellent tolerance to the strong acids, bases and organic solvents commonly encountered in medical environments.

Semiconductors O-Rings

In semiconductor applications, FFKM O-rings provide protection against contamination, while offering excellent chemical resistance and thermal stability. Thanks to their anti-expansion and anti-fragility properties, they are also ideally suited to the chemical processes used in advanced electronics.
