About PTFE O-Rings
PTFE (Polytetrafluoroethylene) O-rings provide the broadest chemical resistance of any elastomer, withstanding virtually all acids, bases, solvents, and oxidizing agents. They are FDA-approved for food and pharmaceutical applications and operate from -320°F to +500°F (-196°C to +260°C). PTFE O-rings are used in semiconductor manufacturing, pharmaceutical equipment, and aggressive chemical processing where other materials fail.
