Krytox™ | McMaster-Carr
Tackier than gear box grease, this grease sticks to open gears and roller chain. It resists moisture for corrosion protection and can lubricate under heavy loads.. NLGI viscosity grade is a rating of a grease's consistency. NLGI 2 is about the consistency of peanut butter. Synthetic-oil-based grease lasts longer than mineral-oil-based grease and withstands a wider range of temperatures.
