VNIINP-279 grease

VNIINP-279 grease (GOST 14296-78) is a synthetic hydrocarbon oil thickened with modified silica gel. Main performance characteristics: good antiwear characteristics, high mechanical, thermal, colloidal stability and low protective properties; stable when working in aggressive environments. The grease has the sealing properties. It is efficient in contact with aggressive environment at temperature ranges from - 50°C to + 50°C and air at temperatures ranges from - 50°C to + 150°С.

It is used in rolling and sliding bearings, threaded connections, connectors, valves and other parts operating in air in aggressive environment.
