Ecolubrium High Temperature 46 is a very high viscosity hydraulic oil which maintains its viscosity and strength at higher temperatures as well as its ability to remain constant under lower temperatures. This ability helps maintain accuracy of movement in machine rams, protects seals and pump parts whilst increasing the life of the oil. This is the ideal product for hedge cutting equipment, hydraulic wenches, and other high temperature high pressure situations. DIN 51524 Part 3.
