SAF-T-EZE Nickel Grade Anti-Seize is recommended where very different metals are used together such as brass and steel because Nickel is a very unreactive metal that protects and lubricates the metallic surfaces. It is also used where high Nickel alloy metals such as Stainless Steel, or where Titanium or other hard metals are involved. Nickel Anti-Seize is also used where metals such as copper cannot be present such as in caustic, ammonium or high acidity processing plants. Surface need not be cleaned before application unless grit or low quality oil/grease is present and ultimate performance is required. Use on threaded parts, bushings, gears, valve stems, chain sprockets, levers, hinges, pivots, rollers, heat exchanger or manifold bolts, or as a gasket release agent, etc.
