Chemours’ Krytox brand includes an automotive grease compatible with all seal materials, according to the company. The white, additive-free grease offers good adhesion properties and greater high-temperature stability than the seals themselves while resisting oxidation and carbonization. Krytox GPL 205 PFPE grease can aid in assembly and improve O-ring durability and reliability at temperatures from -36 degrees Celsius up to 210 C. The company’s e-book gives details on this product and other under-hood lubes. Web: www.chemours.com
