VNIINP-263 grease

VNIINP-263 grease (GOST 16862-71) - petroleum oil thickened with modified silica gel; contains a multifunctional additive. Grease has a good water and frost resistance, dries at temperatures above + 100°С; ensures the tightness of the threaded connection at normal pressure and shallow vacuum. It is efficient within the temperature range from -50 to + 100°С. Provides tightness of threaded connections, facilitates thread screwing in and out. Substitute - R-416.
