If you're looking for a lubricant of the highest purity, choose LOCTITE^® LB N-5000. This nickel-based anti-seize lubricant paste is carefully produced under controlled conditions to ensure the lowest practical levels of halogens, sulfur and heavy metals, including copper. The high-purity formulation prevens stress corrosion during operations – even at operating temperatures up to 2400°F (1315°C). During disassembly, it prevents seizing, galling, and destruction of threads to ensure their robustness and longevity. LOCTITE^® LB N-5000 is ideal for use on bolts, studs, valves, pipe fittings, slip-fits, and press-fits in industrial installations such as nuclear power generating plants, chemical plants, pharmaceutical plants, and paper mills where stainless-steel fasteners are used.
