Bostik Never-Seez Pure Nickel Special Compound

This has been an industry-leading thread lubricant applied to nut and bolt assemblies. Serving as a protective coating, it remains on metal parts even after extended exposure to the elements.
Copper-based, this type of Never-Seez protects parts against the following in particular:
Rust and corrosion
Excessive wear due to extreme pressure and/or high temperatures
Additionally, with a temperature range of -297 to 1800°F, the Regular Grade product provides protection for easier dis-assembly. This allows for faster, more accurate repairs.
Application
stainless steel pipe fittings
flanges
steam generators
fasteners exposed to high temperatures
fasteners in exhaust manifolds and boilers
