Y VAC 3 is 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 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.
