Electrical Connections: Whether to Use Dielectric Grease or Not OEMs often use dielectric grease on the pins inside weather-tight connectors These kinds of sealed connections seldom give trouble: I could see an issue with trailer connections (like the example below), though the issue could be conductive debris and not the dielectric grease itself Again, this could be tested with a quality volt-ohmmeter
Dielectric grease for electrical connections - Adventure Rider Dielectric grease in these connectors will act as an INSULATOR and will significantly change the electrical signal which is sent through the circuit I have MEASURED this change using a Fluke meter and the change in current flow is measurable when dielectric grease is used in the connector
Dielectric grease - Adventure Rider Dielectric grease It is often applied to electrical connectors, particularly those containing rubber gaskets, as a means of lubricating and sealing rubber portions of the connector without arcing A common use of dielectric grease is in high-voltage connections associated with gasoline engine spark plugs
Dielectric Grease Properties? - Adventure Rider I use dielectric grease on every connection that I break and put back together I would think that "non conductive" would be good 'cause you want the current to go thru the connector, not thru the grease I got a can of it at a local auto parts place for about 8 buck IIRC It will last me a few years
Do Not Clog O2 Sensor Air Vents with Sealant, Anti-Seize Paste or . . . There are areas where you should not use dielectric grease, RTV sealant or anti-seize paste One worth mentioning is certain oxygen sensors (O2 devices) Some O2 sensors draw ambient air where the wires enter the sensor housing Sometimes There is a port like the vent opening shown in the illustration below
Has anyone used conductive grease. I have an electrical connection Dielectric grease does not conduct Dielectric means it's an insulator It repels water and helps prevent corrosion but the metal parts within have to make contact There are conductive greases on the market but it's not a good idea to rely on it to conduct enough power to light a headlight Also, if it migrates it can cause a short circuit
What do you use on electrical connections? | Adventure Rider I notice NAPA sells a decent sized tube of silicone based dielectric grease If you're a lab rat, Dow-Corning stopcock grease is silicone based and will do the job Honda auto dealers used to sell a tube of silicone grease for use in greasing lubing the rubber seals and mechanicals for their targa (del Sol) and convertible (S2k) topped cars
Electrical connectors WD40, grease, Vaseline? All . . . - Adventure Rider I am a huge fan of dielectric grease Mostly from my experience with leaky convertible VWs, but I digress You don't need much, and it works If you are cheap, Home Depot has Ideal No-Al-Ox in 4oz bottles, and it's half the price of the Permatex stuff, identical in content
