Dielectric Grease
Dielectric grease is a non-conductive silicone grease that seals electrical connectors from moisture.
What is Dielectric Grease?
It is applied to seals and housings. It is used on bulb holders and plug boots. It does not improve conductivity. It is often applied to the rubber boots of ignition coils and to trailer sockets that are exposed to water. Some connectors with gold-plated pins or very small signal currents should be left dry, so follow manufacturer advice. Grease will not fix a connector that is already corroded; clean it first.
How it works
The grease keeps water and air out.
Why it matters for your car
Do not fill sensitive connectors unless approved. Clean corrosion first.
