Grease for deckplug ?

[webcraft]

.
All the cables that come down our mast go into one large, complex deckplug. There are nine terminals inside the main part of the plug, plus a co-ax cable. I have now got it all apart to fit a new wind instrument (which is 5 of the nine terminals in the plug!)

Everything was covered in grease of some sort but there was still some green corrosion. I've cleaned it up but am now wondering whether to refill it with grease when I re-assemble it - or at least smear some grease over the terminals. Should I, and if so what sort of grease should I use?

I use a Canadian spray called Corrosion Block. It is actually a thin grease intended for the job and it works. It is expensive, but a can goes a long way.

I've used Vaseline in the past, but not found it to last very long.

Thanks, I'll have a look for 'Corrosion Block' when I go to Ardfern today or tomorrow. If however it comes down to a choice between Vaseline and ordinary marine grease, which is best?

a di-electric grease is preferable for multiplugs and various other types of electrical fittings.

corrosion block which the other op mentioned is dielectric, so a good choice. http://www.ebay.co.uk/itm/ACF-50-AC...54?pt=UK_Motorcycle_Parts&hash=item564fc7c71a

Is Vaseline di-electric?

I've always used a bit of silicon grease. I don't know if it is right or wrong but it seems to work.

Nick,
try Lanolin.

It is di electric, anhydrous and can be used in many boating applications for corrosion protection, propellers for anti barnacle, and sore nipples for breastfeeding mothers.

I used to use vaseline but didn't find it too effective for long. I have just bought and applied some of this: - Contralube

Early days - we will see if it lives up to its promise.
I am also a fan of Lanolin, always have a tub on the boat. Bought mine from a theatrical riggers at a good price.

don't think it is, it does perish rubber gaskets in time, where dielectric grease does not.

I have used radiospares (RS components) silicon grease successfully for years.

(Sigh) Silicon is an element, symbol Si, used in the manufacture of computer chips, transistors etc. It is widely found in nature as silica - silicon dioxide - in sands and quartz.
Silicone is the "friendly" but potentially confusing name for polysiloxanes. These are complex synthetic polymers which contain silicon, but other elements as well. They are used in sealants, adhesives, lubricants, implantable medical devices, cookware, electrical insulation etc. etc.

I use Contralube 770 which I thought I'd bought from Maplins but they don't seem to stock it now I look. This has taken over from vaseline which might be what you have found in your deckplug, Contralube is the pukka stuff : it's more expensive than vaseline and has other properties I know nothing about

Well, I ended up using some expensive silicon grease I got from a swindlery for a tenner. Fingers crossed.

Contralube 770

Contralube 770 has just been re-launched in a smaller pack size. Maplins may not have restocked yet. I bought some recently on eBay in the old larger pack size after reading of it's praises on here. There are still some to be had in the larger pack size on eBay.
