Electric contacts protection spray

[the green vanper]

Hello,

I'm looking for good protection spray to protect electric connectors.

I know such things exist, playing with a part for my non-FIAT daily I got from a breaker once I removed the sealed plug with like 20 connectors inside, they were all covered with a blueish fluid. The donor car was like 20 years old, I sprayed the contacts with IPA and they look like new.

So, it must be conductive and protect from oxidation on the other hand.

Any recommendations, please?

Vapourmatic and whoever owns the AC auto brands (AC90 etc) both do good contact cleaners and sealers

You don't want it conductive for multicontact connectors! , think about it.

The only time you want it conductive (say copper loaded etc) is when it's a single connector/connection like a battery post.

The pressure mechanisms of the connector will push through it and make the connection.. you're just trying to prevent the atmosphere getting to the metalwork of the connection surfaces and causing tarnishing/corrosion.

Google stuff like "SGB20S" or generally just "contact grease"

I use dielectric grease from a tube. I spread it with one of those cheap plastic paint brushes the kids use. The kind that come with those paint by number kits. Not sure if there is anything better but it seems to work well.

Hello @the green vanper

Bit late to the party, but ACF50 is my choice - I have put it to good use on a number of my past commuter motorcycle electrics.You don’t need a lot in connectors, in fact I tend to brush some on with a touch up brush. If I’m using crimped connections which are exposed to the elements I dip the wire and crimp in it, then seal over with heat shrink.

It’s a good product developed for Aerospace but utilised in Marine and Automotive Industries
