About DuPont 240AZ_1_2oz Krytox Mil-Spec NLGI 1
The 240 Grade Greases are the original products that the MIL-SPEC PRF-27617 was written for and have been continuously certified as such since. Many synthetic greases show excellent performance in one or more categories, but only Krytox Greases combine stability, and chemical inertness with outstanding lubrication performance under a variety of conditions. Krytox greases have excellent mechanical stability in bearings. They do not break down under mechanical stress and lose their ability to hold oil. Krytox 240 series greases are mixed in a grease worker for 60, 10,000, and 100,000 strokes and tested for changes in hardness. All Krytox 240 series greases had changes of less than 30 points on the NLGI penetration scale and were within 1/2 grade of their original starting point. Roll stability tests were performed according to ASTM D1831 for 2 hr with the 4500-lbf reference load. The penetration change was minor and was within 1/2 grade of the original starting point.
