Contralube 770 - Electrical Grease

Contralube770 was originally designed for the automotive industry. The auto industry are constantly battling with vibration corrosion and water ingress problems in their connectors/circuitry.

This state of the art grease can protect all your connections – multipin connections, spade contacts, battery connections, external antennae connections; pretty much everything electro/mechanical, its also compatible with most plastics so there is no need to worry there.

Contralube770 is primarily a electrical contact grease but it can be used for loads of different jobs.  A run through some of the many automotive applications for Contralube:

Electrical connections (multi-pin, bullet, spade etc), automotive bulbs contact areas, spark plug boots, distributor/ignition systems, hinges, locks, latches, trailer hitch electrical connections, springs, gears, seat tracks, battery terminals, door latches, antennas and much more....

Ever had those annoying ‘gremlins’ in you wiring – engine management type warning lights appearing now and then? This type of intermittent fault is sometimes a sign connectors or contact surfaces are being affected by oxidation or may be moisture finding its way in to your equipment – a small application of contralube770 would stop all this hassle and is more of a permanent solution than traditional solvent spray lubricants. Contralube is a big favourite in the classic car market for just this type of problem.

While contralube770 protects your connector, it also helps the assembly of connectors – especially the larger connections. Many connector faults are the result of forcing male and female parts together at incorrect angles, mostly due to the connectors being located in hard to reach places. Contralube770 is effective at reducing the mating force required, ensuring solid connections and efficient assembly.

How do I use Contralube770?
Apply generously to the connector or contact surface you wish to protect. In the case of multi pin connectors, squirt directly into the male and female pins/holes of the connector you wish to safeguard. Administer to any spade, bullet or any other type of push fit connector. Contralube is good for any metal to metal contact – for instance an external antenna /RF connection. It can be used to protect CCTV connections and is particularly useful for radio controlled model enthusiasts.

How much Contralube770 should I Apply?
So long as your contact forces are sufficient (the amount of pressure that is keeping the conductive contact areas together), you cannot over use contralube770.

How does contralube770 work?
Contralube will weather proof/protect your connection and help stop rust, vibration corrosion and the general build up of oxides. You can load up your electrical and non-electrical connectors and connections safe in the knowledge it will not interfere with the current flow or in the case of non-electrical connection, it will not harm or weaken the signal that is going through the connection eg radio waves or digital signals – amazing hey!
A good description of how contralube770 works is available in a downloadable PDF – Why contralube?
I am applying contralube770 to my multi-pin connector, will it cause ‘shorting’ between the pins?

Contralube can be termed ‘dielectric’ which translates to – A material which has negligible electrical or thermal conductivity. Although contralube770 may be physically bridging a gap between two separate pins/circuits it will not allow the current to pass between the pins. Contralube770 has similar conductive properties to air, so if you do not experience arcing/shorting between pins in unlubricated connectors then the addition of contralube770 should not change the performance/characteristics of the component.
Obviously, circuits utilising extreme currents/voltages are a different matter. We would recommend test/evaluation of contralube770 before using operationally in all circumstances where extreme currents/voltages are concerned.

How should Contralube770 be stored?
Tubes of contralube770 should be stored indoors with the screwcap in place and seated correctly. Storage should also be out of direct sunlight and not in extremely hot and cold environments. Please try to keep the tube inside the orignal carton along with the instruction/support information paper insert.

Contralube770 seems to turn blue, why is that?
The product contains a UV Tracer additive incorporatedinto it. Contralube770 will look clear in appearance although the UV tracer additive means that it will turn a shade of blue when exposed to UV light/sunlight.Sometimes only a small amount of contralube770 is used on small connectors. When dispensed in small amounts it is hard to see and the UV Tracer makes the product visible under UV light which assists with quality checks & inspections.

What about the functional life of contralube770?
Shelf life is the period following the lubricant’s manufacture during which it is deemed suitable for use without re-testing its physical characteristics. Functional life is determined by durability or accelerated life testing of contralube770 in a component under expected operating conditions.
Contralube770 is designed for lifetime component lubrication, which often exceeds 10 years in extreme operating conditions.

What is the shelf life of your contralube770?
The shelf life is four years from date of manufacture, provided that the oils and greases are stored in their original, unopened container. The product should be stored away from excessive heat.

How can I clean or remove contralube770 from my component?
Start by wiping off all the grease you can reach. Then wipe or brush all surfaces with a solvent cleaner (isopropyl alcohol or similar).
