Loctite C5-A Copper Anti-Seize 4 oz

Loctite C5-A is a copper-based anti-seize lubricant supplied in a four-ounce can. The grease suspends copper and graphite to protect metal parts from rust, corrosion, galling and seizing while establishing greater clamp load. It is intended for automotive and industrial maintenance where threaded fasteners must release cleanly after high-temperature service. Mechanics and DIY owners working on exhaust, brake or manifold hardware will find it matches the requirement.

Brush-top can for direct application

The container includes an integrated brush lid so the compound can be applied straight to threads or mating surfaces without extra tools. Surfaces should be cleaned first to ensure the grease adheres and the copper-graphite mix distributes evenly. Over-application can attract dirt or contaminate nearby sensors, so a thin, uniform coat is recommended. The product is not a penetrating oil and will not free already seized bolts without prior mechanical effort.

Questions about this item

How can I confirm the Loctite C5-A is protecting threads after assembly?

After torquing the fastener, disassemble it later and inspect the threads; they should turn freely without galling, rust or corrosion, showing the copper-graphite grease did its job.

What comes in the box and is anything else required to use the Loctite C5-A 4 oz can?

The box contains one 4 oz can of copper-based anti-seize lubricant with a built-in brush-top applicator; no additional tools or accessories are needed for application.
