Dielectric grease VS water proof grease
1 Attachment(s)
I was told by a Tech at MSD I should be putting a waterproof type grease on my connectors on my distributor.He said the waterproof grease that was white was better for conections than the Dieletric grease.
I cant find any stuff like he recomended. or do I really need it? Like for the plugs to this style GM 8-Pin Module Thanks for any input Rob:drink: |
I use whats called" tune up grease" by Permatex sold at Murrays auto.Might be the same as dieletric.

Try www.mcmaster.com search PN 1204K12 they have a few choices. I cant seem to link that page.

dielectric grease is great on new clean connections, it can cause all kinds of problems when used on slightly corroded connectors.
I use it everywhere possible on the boat and on my atv and have been doing so for a few years. |

Try your local motorcycle shop. Ask for bel ray waterproof grease. Used it on all the stuff on the jet skis , connectors , plug boots , I used to sink them a lot. http://www.belray.com/consumer/product.fsp?pid=13631
And no this wasn't photo shopped! |

there are some spray electrical contac cleaners out there that work well and one that the local marine shops seem to prefer, unfortunately i cant think of the name at the moment. I'll try and remember. |
Ive always used dielectric on all concealed connections new or used never had any problems. You shouldnt need waterproof grease there hopefully its not getting wet. Just get out the KY and use that!
|
I've been using the dielectric lube from Merc for years. Its good stuff.
|
NAPA has "waterproof" grease, it is red in color. Pennzoil makes a white grease;
http://www.pzlqs.com/Tech/Pdsheet/Do...eGrease705.PDF Spray Lithium grease is usually used for corrosion protection. |
You need to be very careful if using any actual "Grease" on low voltage electrical connections. Many types of waterproof "grease" contain enough mineral materials to conduct electricity. 5 volt signal circuits don't like losing any voltage across circuits( ie inside connectors ) so only a high quality dielectric compound should be used.

I've been using Corrosion Block Dielectric grease for several years on my boat with no problems. I figure it helps fight any corrosion that might already be on a connection.
|
so I shouldnt have put di-electric grease in my spark plug boots?
|
Isn't dielectric grease just silicone grease? That's what the 3M stuff is that I have.

It is a good place for it, stops water getting in and starting corrosion. |

Michael It is not di-electric unless it says it is. |
Okay so what is a good off-the-shelf dielectric grease brand that may come in a spray can or something besides those little squeeze tubes? I'm looking for quantity & good shelf-life in my shed when not in use.

Available in cans or 8 oz tubes from MSC |
Is this available off the shelf like in Pep-Boyz, or Advance Auto, etc.? Or via website?

Di-electric grease by definition is non-conducting, corrosion makes for poor conduction, put the two together and you may compound a problem, I have seen that happen on race cars.
Exactly, regular grease, even waterproof is not di-electric(non-conducting) whilst it is great for battery terminals etc. However di-electric grease is great for waterproofing a connection and sealing it from the air, thereby stopping oxidation and corrosion where it matters. Do they make a conducting water proof grease like for termanal conections.If the di electric grease does not make good conduction/conection,what should ya use ? |
