Seals Eastern, Inc.
Perflas® 9295 Seals, gaskets, and o-rings
Perfluorinated rubber for high temperature and chemically aggressive applications
Perflas® 9295 Seals, gaskets, and O-rings
Offer high temperature service and are resistant to aggressive chemicals. They are a thermally stable, perfluorinated elastomer (FFKM).
Perflas 9295 seals offer outstanding resistance to high temperature (320°C/608°F). Perflas 9295 seals resist attack by nearly all chemical reagents, including organic and inorganic acids, alkalines, ketones, esters, alcohols, fuels and high pressure steam.
