Loctite Silver-Grade Anti-Seize Lubricant 1 lb Brushtop — High-Temp 1600°F, Graphite/Metallic Paste

Loctite 501001 Silver-Grade Anti-Seize is a heavy-duty, petroleum-based lubricant with metallic flake and graphite designed to prevent seizing, galling, and corrosion in assemblies up to 1600°F (871°C).

This brushtop 1 lb can delivers a paste-like anti-seize compound for industrial and automotive fasteners, fittings, and assemblies exposed to extreme heat and pressure. Formulated to remain stable across very low and very high temperatures, the product resists evaporation and hardening so threaded connections and metal surfaces stay serviceable during maintenance and disassembly.

How does this anti-seize help with high-temperature assemblies?

The silver-grade formula includes metallic flake and graphite that create a durable barrier between metal surfaces, reducing friction and stopping threads from welding together under heat. It's rated for use in applications up to 1600°F (871°C), making it suitable where conventional greases fail.

• Temperature rating to 1600°F (871°C)
• Graphite and metallic flakes for long-lasting surface separation
• Resists evaporation and breakdown at high temperatures

Will it protect against corrosion and seizing in harsh environments?

Yes — the petroleum base combined with solid lubricants provides a protective film that slows corrosion and prevents galling on threaded parts and flanges. Because it stays pliable in both extreme cold and heat, it maintains protection during storage, operation, and maintenance.

• Forms a moisture-resistant barrier on metal
• Prevents rust-related locking and seizure
• Stable in extreme cold without hardening

How is the brushtop can convenient for maintenance tasks?

The integrated brush top lets technicians apply paste precisely to threads, studs, and fitting faces without separate tools, reducing waste and cleanup time. The 1 lb container supplies enough compound for multiple service jobs while keeping the product covered between uses.

• Brushtop for direct, controlled application
• 1 lb size balances capacity and portability
• Paste consistency clings to vertical surfaces and threads

What surfaces and parts are suitable for this lubricant?

Designed for metal-to-metal contact, it works well on steel, stainless, cast iron, and many alloys used in engines, exhaust systems, boilers, and heavy machinery. Avoid use where contact with combustible fluids or food-contact surfaces would be an issue; consult material compatibility for specialty alloys.

• Use on threaded fasteners, studs, flanges, and spark plugs
• Ideal for exhaust, manifold, and high-heat bolting applications
• Not intended for food-contact or certain specialty non-metal components

Who is this for: Loctite 501001 Silver-Grade Anti-Seize is aimed at mechanics, fleet maintenance crews, fabricators, HVAC and boiler technicians, and industrial service teams who need a reliable, high-temperature lubricant to keep fasteners serviceable and machinery maintainable. If you require a paste that endures extreme temperatures, prevents seizure and corrosion, and is easy to apply with a brushtop can, this product fits routine repair and heavy-duty industrial needs.
