How Do I Select the Right FFKM O-Ring Material?
Selecting the correct FFKM material requires more than simply checking the maximum temperature.
The main factors include:
Chemical compatibility
Operating temperature
Pressure and vacuum level
Static or dynamic sealing
Plasma exposure
Compression set requirements
Required service life
Cleanliness requirements
Semiconductor process conditions
Regulatory or certification requirements
For replacement projects, the existing material grade and actual operating conditions are especially useful.
If you are replacing a Kalrez®, Chemraz®, Perlast®, or another FFKM O-ring, providing the original material grade can help our technical team identify a suitable BoilPeak alternative.
