  • Non-conductive formula safe for rubber, plastic and ceramic

Dielectric Grease for Electrical Connectors

This 1 oz tube of non-conductive silicone paste protects automotive and electronic connections from moisture, corrosion and voltage leaks. It is formulated for mechanics, builders and engineers who need reliable insulation on battery terminals, spark plug boots and sensor connectors. The grease seals out contaminants while remaining safe for rubber, plastic and ceramic components.

Wide Temperature Range -40°F to 428°F

The single specification that decides suitability is the operating window of -40°F to 428°F. This range covers extreme cold starts, engine bay heat and marine environments without melting, freezing or washing out. If your application exceeds these limits, a different compound is required.

1 oz Capacity for Targeted Jobs

The 1 oz tube (0.05 kg) provides enough material for dozens of connector coats, boot installations or terminal treatments. It comfortably handles routine vehicle maintenance, boat wiring and outdoor lighting repairs. Large-scale harness work or fleet servicing will consume the tube quickly and demand a larger container.

Questions about this item

What does the 12 g tube size mean for typical connector jobs?

The 1 oz container holds about 12 g of grease, enough for dozens of battery terminals, spark-plug boots or sensor plugs in automotive and marine use.

How does the silicone dielectric formula affect voltage leakage on live circuits?

The non-conductive silicone seals out moisture and contaminants, preventing arcing, short circuits and voltage leaks up to the product's rated temperature limits.

What temperature range can the grease withstand once applied to a connector?

It remains waterproof and salt-resistant from -40 °F to 428 °F, so it stays effective in engine bays, exhaust areas and marine environments.
