Chemours aims to boost exhaust gas recirculation valve performance with a PFPE grease for actuator gears. Extensive testing proves its effectiveness in this sealed-for-life application at temperatures ranging from -36 degrees Celsius to 210 C and under heavy vibration conditions, the company says. Krytox XP 2C5 grease contains anticorrosion and anti-fretting additives and is resistant to diesel exhaust fumes and high operating temperatures, extending EGR valve life. The company’s e-book gives details on this product and other under-hood lubes. Web: www.chemours.com
