FomblinŽ Y VAC3 YVAC3 YVAC 3 is a homogeneous white grease particularly suitable for use as a lubricant of mechanical parts operating at high vacuum and in contact with aggressive chemicals or oxygen. Y VAC 3 is used in "lubricating for life" applications. Its lubricating properties make it suitable for parts requiring boundary (extreme pressure) lubricating properties. Its welding point, in Shell four ball EP tests, is 620 kg. Y VAC 3 can be used to lubricate mechanical parts subjected to high thermo-mechanical stress. Y VAC 3 can be used for long periods of time and at very high operating temperatures (from -20° C to +200° C) and is therefore widely used in the manufacturing, aeronautical, and electromechanical industries. Sold in 100 gram tubes. For MSDS Sheet on FomblinŽ Y VAC3 See Available Downloads below.
