O-ring 10x2,5 FFKM75

FFKM O-rings – Superior Resistance in Extreme Conditions

O-rings made of FFKM material (also known as Kalrez) are designed for the most demanding industrial environments. They combine the flexibility of classic elastomers with the exceptional chemical resistance of fluoroplastics, ensuring reliable sealing even in conditions where other materials degrade.

Key advantages of FFKM O-rings:

• Unmatched chemical resistance – resistant to most aggressive chemicals, including acids, amines, solvents, and hydrocarbons.
• Wide operating temperature range – from -20°C to as much as +327°C, depending on the type of compound.
• Excellent thermal stability – retain flexibility and tightness even after prolonged exposure to high temperatures and pressures.
• Minimum outgassing and material purity – enable use in processes requiring high purity, such as in the semiconductor and pharmaceutical industries.
• Extended service life – significantly reduces the need for frequent inspections and seal replacements.

Applications for FFKM O-rings:

• Chemical and petrochemical industry
• Semiconductor and electronics production
• Pharmaceutical and biotechnology industry
• Pumps, valves, process reactors
• High-temperature and vacuum applications

Why choose FFKM?
Perfluoroelastomer O-rings are the highest class of elastomer seals. Their unique chemical structure provides exceptional resistance to extreme operating conditions, translating into longer equipment life, greater process safety, and lower operating costs.
