Extreme Fluoro Grease is made with 100% pure DuPont® fluorinated ingredients. Recommended for precision parts, especially bearings (including ceramic). Perfect for those seeking a significant drop in friction and maximum protection against extreme pressures and/or extreme rotational heat. Also works great on cable wires, derailleur pivots, stanchions, gaskets, pedal springs and as a clean alternative to conventional anti-seize compounds. Extreme Fluoro often provides 'lubricated for life' protection!
