Tel: 732-747-9200

Perflas® 7265 Seals, gaskets, and O-rings

are made of a chemical resistant, highly fluorinated (~ 67% Fluorine by weight) elastomer (ASTM D1418 Class: FEPM). Perflas 7265 seals offer outstanding resistance to high temperatures (230°C/446°F) and aggressive chemical environments. Perflas 7265 seals resist attack by many chemical reagents, including organic and inorganic acids, alkalines, ketones, esters, alcohols, fuels and hot water. Perflas 7265 can frequently withstand enviroments handled by FFKM's at a lower cost.
