Permatex Anti-Seize Lubricant 12 oz Aerosol Can — Aluminum/Copper/Graphite, High-Heat Protection to 1600°F

Permatex 81464 Anti-Seize Lubricant is a high-temperature aluminum, copper and graphite blend in a 12 oz aerosol that prevents galling and seizing and makes metal parts easier to disassemble.

When you’re assembling or maintaining engines, exhaust systems, marine fittings or fasteners exposed to weather and chemicals, a reliable anti-seize helps protect threads and metal surfaces from corrosion and binding. Permatex 81464 delivers a refined mix of metallic particles and solid lubricants formulated to resist salt, moisture and high heat so parts release cleanly after long service or exposure to extreme temperatures.

How does Permatex 81464 protect fasteners in high heat?

The formula contains aluminum, copper and graphite solids that form a heat-stable barrier between metal surfaces. That barrier reduces metal-to-metal welding, galling and cold-seizing at elevated temperatures, preserving thread integrity and making future removal far easier.

• Temperature range rated up to 1600°F (871°C) for hot applications
• Aluminum and copper particles prevent corrosive bonding
• Graphite adds dry-film lubricity to reduce friction under load

Is this safe for marine and corrosive environments?

Yes — Permatex 81464 is designed to resist salt, moisture and corrosion, making it appropriate for marine hardware, trailer fittings and other outdoor metal assemblies. Its corrosion-resistant solids help maintain a protective film even when exposed to water and road salts.

• Formulation resists salt spray and moisture intrusion
• Useful on propeller shafts, fasteners and boat hardware
• Helps prevent galvanic corrosion between dissimilar metals

Where and how should I apply this aerosol anti-seize?

Apply during assembly to threads, studs, bolts, splines, hinges and mating metal surfaces to prevent future seizing and ease disassembly. Shake the can, spray a thin even coat, and allow any carrier solvent to flash off before final assembly for best performance.

• Suggested on spark plugs, exhaust bolts, cylinder head bolts and anchor pins
• Works on u-bolts, spring bolts, gears, chains, sprockets and rollers
• Aerosol delivery reaches tight areas; wipe excess to avoid contaminating sensors

What performance benefits can I expect during maintenance?

Expect reduced torque variation and smoother removal of fasteners after exposure to heat or corrosive conditions. The anti-seize layer lowers friction and stops parts from freezing together, which saves labor time and reduces the risk of damaging threads when disassembling.

• Simplifies removal of rusted or heat-exposed bolts and nuts
• Helps preserve torque accuracy on future assemblies
• Reduces the chance of broken studs and rounded fastener heads

Who is this for? Permatex 81464 Anti-Seize Lubricant in a 12 oz aerosol is suited to professional mechanics, marine technicians, fleet maintenance teams and DIYers who work with high-temperature or salt-exposed metal assemblies. If you regularly service engines, exhaust systems, trailers, or outdoor fasteners and need dependable protection against galling and corrosion while preserving ease of future maintenance, this product provides a durable, heat-resistant layer to protect metal parts during assembly and long-term use.
