VNII NP-282 А and VNII NP-282М А are lubricants intended for sealing and greasing attrition faces of various equipment units functioning at different loading in contact with aggressive media and gaseous oxygen. It is permissible to use lubricants in powerful mechanisms and the armature of oxygen-respiratory devices at the temperature not lower than minus 60 °С. The lubricants possess increased stability against oxygen and the influence of aggressive media (acids, amines, hydrazines). The stability decreases because of a continuous contact with nitric acid and hydrogen peroxide.
