Contralube 770 is a premium electrical contact protector in the form of a clear gel that prevents moisture ingress, oxidisation, corrosion, verdigris, contact wear and fretting corrosion and ensures your connections remain as reliable as the day they were first made. It is ideal for use in areas where connections are subject to harsh environments and is especially useful for the protection of marine electrics. It can be used on all types of electrical contacts: push-fit, screw, multi-way, battery terminals etc. and is also suitable as a weatherproof packing grease in terminal entry holes.

The gel itself is non-conductive so cannot cause accidental shorting and it does not increase contact resistance because it is pushed aside by the contacts when they are mated so that the micro 'peaks' of the contact surfaces touch, whilst the gel sits in the 'troughs' and around the outside of the contacts.

To use, simply apply to the terminals or contact surfaces to be protected ensuring full coverage. For multi-way connectors it can be applied directly onto the pins and into the sockets.

Sold individually in 8g sachets.

  • Fretting corrosion is an abrasion of metals in contact caused by low amplitude vibrations or thermal expansion/contraction.

Contact grease

Difficult to review as more time needed to see if it works. May provide protection stated on new untarnished connections. Does not say in instructions what you should do with existing tarnished connections, do you need to clean them?

Great product

I.m dropping the mast on the yacht - a major operation. I use Contralube to protect the bulb contacts in the masthead lights from corrosion as they won't be accessible again for years.
