Loctite C5-A Copper Anti-Seize Lubricant

Loctite C5-A is a copper-based anti-seize lubricant supplied in a one-pound brush-top can. The formula suspends copper and graphite in a high-quality grease to protect metal parts from rust, corrosion, galling, and seizing. It helps establish greater clamp load during assembly. Suitable for automotive and industrial maintenance tasks where threaded fasteners require reliable lubrication and protection.

Thermal stability and application

The copper and graphite formulation maintains lubricity across a wide temperature range typical of exhaust manifolds, brake calipers, and engine components. It reduces friction during tightening so torque readings reflect true clamp load without galling. The brush-top container allows precise application to threads and mating surfaces with minimal waste or mess. No special ventilation or curing time is required for normal use.

Questions about this item

How do I apply the Loctite C5-A Copper Anti-Seize Lubricant using the brush-top can, and what step is often missed?

Brush a thin, even coat onto clean, dry threads or mating surfaces; the step often missed is wiping away excess lubricant after assembly to prevent contamination of nearby components.

Will the Loctite C5-A Copper Anti-Seize Lubricant need replacement or maintenance after application?

The lubricant remains effective until the joint is disassembled; at that point, old compound must be cleaned off and fresh lubricant reapplied for continued protection against rust, corrosion, galling, and seizing.
