Over 32 Years ago-when the world's first rescue tool was still in development- MCS2361 synthetic hydraulic fluid was selected as the driving fluid for Hurst's life-saving rescue tools. Originally created for aerospace hydraulic systems, Hurst synthetic fluid is fire resistant and is known to perform well in a wide range of temperatures. It is also electrically non-conductive and non-corrosive, thus contributing to a safer environment in inherently hazardous situations. These superior characteristics combine to make Hurst synthetic hydraulic fluid the ideal choice of today's fire and rescue professionals. Features/Benefits: *Fire Resistant *Electrically non-conductive *Non-corrosive *Maintains viscosity over a wide range of temperatures *Long Lasting *Does not evaporate Note: recommended to be changed annually
