Electrical Insulation Grease

AstraVox Silicone Dielectric Grease is a non-conductive paste designed to protect electrical connectors from moisture, corrosion and arcing. It suits automotive, marine and general electrical maintenance where reliable insulation is required. The 1 oz container includes an integrated brush for precise application on terminals, spark plug boots and O-rings.

Temperature Range -50 to 200 °C

The grease remains stable from -50 to 200 °C, maintaining its dielectric strength and lubricating properties across extreme cold and high engine-bay heat. It resists oxidation and decomposition, so it does not dry out or carbonise during extended service intervals. The 0.054 kg tube provides enough material for multiple connector jobs but will not cover large-scale harness rewiring.

Integrated Brush Applicator

The built-in brush eliminates the need for separate tools and reduces mess when coating battery terminals, bulb sockets or brake caliper pins. It allows targeted placement inside tight connector housings where a finger or rag cannot reach. The package contains only the grease tube; no additional solvents, cleaning wipes or protective caps are supplied.

Questions about this item

Will this AstraVox silicone grease protect the connectors on my older vehicle's ignition system?

Yes, the grease is designed for automotive ignition systems, spark plugs and battery terminals. Its insulation properties prevent leakage, short circuits and arcing on older electrical connectors.

How can I confirm the grease is performing correctly after I apply it to spark-plug boots?

After application the connection should remain free of moisture and corrosion. The grease maintains continuous lubrication and insulation across the -50 to 200 °C range, so no voltage leaks or misfires should appear.

Does the 1 oz container include the applicator brush, or must I buy one separately?

The 1 oz container comes with a built-in brush applicator. No separate brush or tools are required for applying the silicone paste to connectors, O-rings or caliper pins.
