All-Union State Standards 3333-80
Graphite Lubricant is intended for greasing hard, heavily loaded mechanisms including open gear-boxes, screw joints, guide screws, jacks, springs etc. The lubricant is efficient at the temperature varying from minus 20°С up to 60°С. The exploitation of the lubricant for springs and other analogous mechanisms at the temperature lower than minus 20°С is permitted.
Guarantee period of storage - 5 years from the day of manufacture.
