trailer plug grease

glennster · Oct 30, 2018

what is your favorite trailer plug grease? i have always used white lithium on the trailer plugs for corrosion. other guys are using silicone die electric, and some just syl-glyde silicone grease or just vaseline. what seems to work best?

I use silicone dielectric grease, seems to hold up a long time.

I'm a firm believer in dielectric grease vs anything else for automotive/trailer wiring

The problem I have is the grease draws dust and dirt then made it hard to plug in.

I have at least six trailers,, never have seen the need for grease in the trailer plug in here, if I did it would be full of dirt,,, as long as both plugs are in good shape in my area there is zero need for it,, now the trailer balls bumper and 5th wheel always get greased to stop wear

I just clean them with contact cleaner otherwise the accumulate a lot of dirt and get hard to plug in.

I use silicone based di-electric paste on all pins and sockets to repel moisture and improve conductivity. When plugged in, wipe it dry. The plug should be booted and sealed against moisture, so if dirt is getting in, maintenance is required.

Can go a little different here. Here in South jersey the salt spreader capitol of the world. I use dielectric grease on the plugs. The socket on the truck has a little molded rubber plug that will squish into it and protect everything. Now the male plug is nice and greasey. Take one of those snack size zip lock bags and stick the plug in and zip it shut. You want to position the wires and bag so no rain can possibly get in. I use a brick sitting on the tounge. Been doing it for years. While you are at it... pour a little drain oil down into your crank up jack stand so it doesn't bind up.

I normally use diarrhea electric grease.

Try Fluid Film. I have used it for years. It does not get hard like the grease does. Plus you can stick the straw back into the plug far enough to keep the back side lubed too. That way if you need to change the wiring the screws are still in good shape.

Don't know. But, a pal of mine is a commercial fisherman (gill net). They have floats with a light on top at the ends of the net (sticks about 2' in the air). The thing uses 1/2 doz. or so 'D' batteries and he packs the case they are in with Vaseline. The case itself is submerged. Works.

Never used anything here in Ohio and never greased the hitch balls either, they don't get that much ware.

silicone dielectric compound... If the corrosion has gotten to the wire nuttin is gonna stop it other than a wire cutter...

I have pulled trailers for years, thousands of miles and never greased a trailer plug.

Stephen, I think the auto-correct gotcha.

I use silicone dielectric grease. I also use it on flashlight batteries.

Noalox. Used it on every main lug panel connection, outside electrical application, and on the battery connections on all power equipment. A little goes a long way.

"Noalox is a product specifically formulated to not only provide corrosion protection but also to improve the electrical connection itself. Unlike dielectric grease or Vaseline, it conducts electricity. It fills the tiny voids between the connectors with and lowers the resistance."

seen many 5th wheel ball sockets here wear through from no grease,, mine is like new with 150,000 miles at least on it,, you must not use yours much if you see no wear on them,, but I am not like most ,, I keep my stuff once I buy it and I want it to last,, I would guess you do not use 20 10 packs of grease a year either like I do,, no that would be silly to grease something to prevent wear,, I am just a dumb old long hair that has been on his own since he was 15, I am sure what you would call a loser

I use Noalax too had a large tub left from previous electrical projects has lasted for 20+ years and seems to work the best for me and better yet I haven't had to buy anything.

I dought I have put 10000 mile on my oldest trailer that I got used sometime over 20 years ago. The other trailer I bought new sometime about 18 years ago and got it wrecked 3 years ago and dought if I averaged 2000 mile a year, probably closer to a thousand and the new one in 15 dought over that many miles. And am retired now so not using grease but whem I was farming a lot of times I would use 5 tubes a day. Grease on that ball would just gather dirt to act as a grindstone to ruin them. Had to grease disk bearings 3 times a day, had one disk had to grease them every 2 hours. Impossible to see how a trailer could get as many miles 150,000 on it. Longest trip I ever made with a trailer was with camper and under 400 miles. And some years total miles were less than that. 30 miles to farthest town I have need to go to.

11 Trailers here
I have tried various compounds over the years and can not say any of them did anything more than cause more dirt to stick to them.

What I do that seems to get everything working 9 out of 10 times is;

Push plug in.

Pull it out and tap it against the bumper with open end facing down.

Repeat 4 or 5 times then blow the crud you have loosened up out of the vehicle socket.

Good connections and grounds are key to avoiding green dust death of wires and plugs.
