LOCTITE® LB 771 Nickel Anti-Seize

LOCTITE® LB 771 Nickel Anti-Seize is a heavy-duty silver metallic paste engineered for maximum efficacy in lubricating and protecting metal assemblies. This industrial-grade lubricant permanently shields components against harsh environments, preventing costly seizing, galling, and rust caused by extreme load, high temperatures, and corrosive elements. Whether you are securing stainless steel bolts or threaded pipe fittings, this premium anti-seize paste provides a robust, defensive barrier on all metals—including specific difficult materials like stainless steel threads and high-pressure press fits.

Why Choose LOCTITE LB 771?

• Exceptional Galling & Corrosion Resistance: Prevents seizing, rust, and wear under extreme load and high temperatures.
• Extreme Temperature Performance: Operates reliably from –65 °F to +2,399 °F (–54 °C to +1,315 °C) while keeping its nickel content intact at elevated heat.
• High-Pressure Wear Protection: Formulated with tenacious metals, oils, and graphite materials that cannot be burned away by slow-moving parts.
• Corrosive Media Tolerance: Exceptionally resistant to attack by acids, ammonia, acetylene, and vinyl monomer.
• Reliable Disassembly: Facilitates easy removal of parts after long-term exposure to extreme heat or corrosive conditions.

Simple Application Instructions

1. Clean: For optimal results, remove dirt, oil, and grease from all mating surfaces and let dry. Stir the paste thoroughly before using.
2. Apply: Apply a light, even coating of the liquid metallic paste to the threads or parts requiring protection.
3. Assemble: Assemble and tighten the parts as required. The formula will provide immediate protection and lubrication without curing. Wipe off any excess paste.

Frequently Asked Questions (FAQ)

What is LOCTITE LB 771 used for?

LOCTITE LB 771 is a heavy-duty anti-seize paste designed for high-temperature and high-pressure assemblies. It is specifically formulated to prevent threaded fasteners and press fits from seizing and galling due to extreme heat, pressure, or chemical attack.

Can LOCTITE LB 771 be disassembled?

Yes. Because it is a non-curing paste, it allows for easy disassembly of parts using standard hand tools, even after prolonged exposure to temperatures up to +2,399 °F (+1,315 °C).

Does LOCTITE LB 771 work on Stainless Steel?

Yes. LOCTITE LB 771 offers robust performance across all metals. It is highly effective on stainless steel threads as well as press fits, reducing friction during tight assemblies where galling is highly common.

Is LOCTITE LB 771 safe for all environments?

LOCTITE LB 771 is highly resistant to acid, ammonia, and acetylene environments. However, it is not recommended for use in pure oxygen or oxygen-rich systems, should not be selected as a sealant for chlorine, and should not be used on high-speed bearings or high-stress Grade 8 bolts.
