Quick Answer: Should I Use Dielectric Grease On Trailer Connections?

Is dielectric grease necessary?

I use dielectric grease on every electrical connector I touch because it is good preventative maintenance including spark plug wires.

But to answer your question it is not necessary but it is better than not using it..

How do I protect my trailer wiring?

Wire loom is basically a sheath that goes over the wiring to protect it from damage. Specifically, I used clean-cut expandable braided sleeving because it would be easier to pass through the tubes the wires on my trailer are routed through.

Is Vaseline electrically conductive?

Vaseline is petroleum jelly and is in fact electrically conductive. That’s why you use it in preference to other forms of grease. It’s purpose is to inhibit corrosion and fill any air gap that would promote ozone build up in the joint.

What gauge wire is trailer wiring?

16 gaugeTrailer wiring generally uses 16 gauge wire, part #16-1-1. However, with a long trailer like yours you may want to go with a larger like 14 gauge #DW07550-1 or even 12 gauge #12-1-1. Each size is sold by the foot.

How do you prevent trailer wires from corroding?

Your best bet to eliminate corrosion in your 7-way connector is to use some Dielectric Grease for Electrical Connectors, item # 11755.

What can I substitute for dielectric grease?

VaselineVaseline can work as a substitute for dielectric grease, the big differences are that it can degrade rubber and plastics over time, and it’s combustible – but I’ve used it in the past on car bulbs, wiring and battery terminals and it hasn’t been a problem yet.

Does dielectric grease improve connection?

Dielectric grease, or tune-up grease, is a silicone-based grease that repels moisture and protects electrical connections against corrosion. … The grease does not conduct electricity, so it shouldn’t be applied directly to the mating surfaces (pins and sockets) of an electrical connection.

Can you use dielectric grease on o2 sensor connectors?

Dielectric grease is fine on the connections; just don’t get any on the sensor.

Can Vaseline be used as dielectric grease?

Vaseline can work as a substitute for dielectric grease, the big differences are that it can degrade rubber and plastics over time, and it’s combustible – but I’ve used it in the past on car bulbs, wiring and battery terminals and it hasn’t been a problem yet.

Is it OK to spray wd40 on electrical connections?

Contact cleaner or in a pinch lacquer thinner or denatured alcohol should be the only thing you use to clean an electrical contact. WD-40 should never be used near anything that you want to remain free moving for any length of time.

What happens if you don’t use dielectric grease?

What happens if you don’t use dielectric grease? Chances are, without the dielectric grease, you will destroy the wire if you have to take one off the plug. The boot will be infused to the plug. That’s why you should use anti seize on bolts so they don’t break off due to aluminum oxidation.

Should I use dielectric grease on ignition coils?

For older ignition coils that have cracks, silicone dielectric grease can also be applied to the shaft of the coil to prevent spark jump, but the permanent way to repair spark jump is to replace the boot or the entire coil. … One common misuse of silicone dielectric grease is applying too much on one area.
