Protection For Electrical Contacts

[Amp1ng]

Hi All,

What's the best thing to prevent oxidisation of electrical contacts in a marine environment.

Thanks.

Gold plating ???

 

[Portofino]

Something to form a barrier to the O2 in the air
WD40 a light oil or petroleum jelly ( Vaseline) .

Contralube 770! Made for the purpose.

Haven't actually been using it long enough to see results, but it certainly seems convincing.

Fantastic stuff, no boatowner should be without it.

Brilliant stuff, also switch cleaner before application if the contacts are not new, but quality contacts to start with don't hurt either.

Is that similar to ACF50?

ACF50 is in aerosol form so, while it's dearer, it seems to combine the penetrating ability of WD40 with the coating ability of Contralube.

No - it's a kind of clear gel. I would blob it over plug pins before inserting them.

ACF-50 has to be reapplied annually. Contralube 770 is fit and forget.

Electrolube is another good alternative, designed for this application, contains lubricants and adds a protective film.

+1 for ACF-50 (& corrosion block) It's an active ingredient that kills rust which becomes inactive after a while but it is also used for protection, a barrier for electrical systems, once on it stays on and continues to act as a conductive barrier. I first used it about 3 years ago and it's still acting as a barrier against corrosion under my bonnet. It used widely by Land Rover owners for protecting their electrics when wading, brilliant stuff... Doesn't wash off etc...

My cockpit Raymarine instruments are in a stainless enclosure sealed from the front (hopefully adequately) but I am concerned about the connections at the back which are just push on tags.

The inside of the enclosure is (via conduit) in contact with engine air so should be warm and dry but only when the engine is running. Condensation is inevitable otherwise,

Would Contralube be effective here?

Squirt/blob of this and job done

http://www.acf-50.co.uk/marine.htm

Used by Navy, Military etc, I use it on clients brand new Land Rovers (ever seen the wiring on a Landy ) If it's good enough for the Naval & Military electrical systems it's good enough for me... An electrical engineer I knew used to use it in the Navy he has come out of the services and has discovered they use it on the ferry cats he now works on.

I think NigelMercier has right.
In the text off ACF50 (Corrosion block) you can read,
(it has a 12 to 18 month active life).
So you need to apply after this time again.

FYI,
My local Maplin told me last weekend that they are no longer stocking Contralube. Some stores have tubes in stock at £7.49. No idea if its true so drove across town to buy one of two tubes left in Bristol

I think they are aiming for the trade market, Maplin are a bit Tandy, IYSWIM.
