Black O-Ring

AFLAS is an elastomer copolymer made of tetrafluoroethylene (TFE) and propylene. It stands out for its resistance to petroleum products, steam, brake fluids, and phosphate esters. It has properties similar to ethylene propylene and fluorocarbon in terms of media compatibility. AFLAS offers fair resistance to brake fluids and phosphate esters, but good resistance to petroleum oils.
