Permatex Nickel Anti-Seize Lubricant 8 oz — High-Temp Copper-Free Paste for 2400°F

When working with high-heat exhaust systems, specialty alloys or assemblies where copper contamination is unacceptable, this nickel-based anti-seize delivers durable protection. Formulated to perform under extreme pressure and temperature, it reduces friction between mating metal surfaces so bolts, nuts and threaded components remain serviceable after repeated cycles and harsh conditions. The 8 oz size offers a workshop-friendly supply for automotive, industrial and maintenance tasks.

How does this anti-seize keep fasteners from locking up in high heat?

The nickel compound creates a lubricating barrier that resists breakdown at elevated temperatures, preventing metal-to-metal contact that leads to galling and seizure. It stays stable and retains lubricity where many oils and greases would oxidize or burn off.

• Temperature stability rated to 2400°F (1316°C)
• Forms a thin, long-lasting film on threads and contact surfaces
• Reduces friction and eases later disassembly

Why choose a nickel anti-seize instead of a copper-based product?

Nickel anti-seize is recommended when copper contamination must be avoided or when working with stainless steel, titanium and nickel alloys that can be sensitive to dissimilar-metal corrosion. It provides similar high-temperature performance while remaining copper-free.

• Safer for use on stainless and specialty alloys
• Prevents galvanic reactions associated with copper traces
• Suitable for critical assemblies where copper is prohibited

What applications and parts benefit most from Permatex 77124?

This product is ideal for exhaust hardware, high-temperature clamps and any threaded joints exposed to heat, pressure or corrosive environments. It’s also appropriate for maintenance tasks where repeat removal and reinstallation of fasteners is expected.

• Exhaust manifold bolts and studs
• Muffler clamps, tailpipe assemblies and heat shields
• High-temperature flanges, bolts and threaded assemblies

How do I apply it for best results and safe handling?

Clean mating surfaces of dirt, oil and corrosion before application for maximum adhesion and protection. Apply a light, even coating to threads or contact faces; avoid over-application, then reassemble parts as instructed by equipment specs.

• Use a brush or applicator to spread thinly and evenly
• Remove excess with a lint-free cloth to prevent contamination
• Follow safety guidance on the product label for ventilation and skin contact

Who is this for? Permatex 77124 Nickel Anti-Seize Lubricant is intended for professional mechanics, fabrication shops, heavy equipment technicians and serious DIYers who work with high-temperature systems or specialty alloys and need dependable, copper-free protection. If you service exhaust components, turbocharger hardware, or assemblies that must be taken apart later without damage, this anti-seize offers a long-lasting solution that helps preserve fasteners and simplify maintenance cycles.
