The product in more depth: Contralube 770 is actually technically classed as a grease but we prefer to call it a gel. It has excellent 'stay-in-place' properties and will consistently out perform the competition. There are situations where a general purpose smelly spray lubricant (you know the brands we are on about) is not the best substance for the job at hand – you need a more permanent solution. Oils too can be very messy so on many occasions Contralube is the ideal tool to lubricate and protect your parts and components.
Contralube 770 will help protect your electrical, electronics and data terminations from moisture (inc. salt water), corrosion, wear, dust, rust, vibration (fretting) damage, verdigris (the green coating that builds up on copper) etc. Amazingly it doesn't affect the current/voltage or degrade the quality of the signal – no more intermittent circuitry problems or gremlins in your equipment!
It can be used on all connector types – multipin, spade, bullet, screw, bayonet etc. and will improve the reliability of connectors and extend connector life.
Note: The information on this page is based on the manufacturer's experience and reports from customers. There are many factors outside their control or knowledge which affect the use and performance of our products, for which reason information is given without responsibility.

Facts and Myths about using Contralube on Electrical connections:-
Surely using a grease on an electrical connection will interfere with the conductivity? Doesn't a grease attract dirt?
These myths are taken head-on and some facts are shared on our Why Contralube? - PDF (146KB). Why not take a look, very interesting document that will definitely enlighten you.
Uses - Multipin Connectors & Connections:-
Contralube770 is ideal for all your multi-pin connectors. Ever had a circuit fault/intermittent problem or annoying 'gremlins' in your circuit? Much of the time, just disconnecting connectors in the circuit and re-seating the connector will cure the problem. Why is this? Could be the build up of oxides on the contact surfaces? Could be water ingress, vibration corrosion..., the list goes on. It is the ideal preventative maintenance solution stop these problems before they occur and it causes less headaches and equipment down time.
You can load up your electrical and non-electrical connectors with Contralube and it will not interfere with the current flow or in the case of non-electrical connection, it will not harm or degrade the signal that is going through the connection, e.g. radio waves or digital signals – amazing hey!
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. Contralube has similar conductive properties to air, so if you do not experience arcing/shorting between pins in un-lubricated connectors then the addition of Contralube770 should not change the performance/characteristics of the component.
Whilst it protects you 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. Also it is effective at reducing the mating force required, ensuring solid connections and efficient assembly.
Uses - Electro / Mechanical & Terminals:-
Contralube770 is good for all terminals – spade, fork, bullet etc. Also battery connections, external antennae connections; pretty much everything electro/mechanical and all metal on metal surfaces. It will weatherproof your connection and help stop rust, vibration corrosion and the general build up of oxides. You can load up the electrical and signal connectors with Contralube and it will not harm/degrade the current/voltage or signal that is going through the contacts – superb!
With a snazzy ultra violet (UV) ingredient in it so that it turns blue when exposed to direct sunlight. Why would we do this? Well some engineer use Contralube in very small amounts and in hard to reach places with the UV ingredient you can use a UV 'black light' to inspect which contacts have been protected by Contralube.
When air gets to copper that green slime builds up on the surface. Well this slime will eventually affect the conductivity of the contact and the connection may fail. Prevention is better than cure right well Contralube has a special 'copper deactivator' that stops the evil green slime building up on the surface.
Here's another example. You know when your torch or remote control stops working if it hasn't been used for some time. You knock it on a hard surface or give it a shake, then it works! Well the reason for this is oxides building up on the contact faces of the battery connection. Contralube will stop this with just a small dab on the contact areas. This kind of problem occurs in many different machines and devices and is the cause of many a gremlin in your equipment – sound familiar?
Noble metals (eg. gold or silver) are sometimes used as a plating on a terminal. A plating can be microscopically porous and can easily be scratched away, even during the initial mating of a connector. Over time nasty oxides of the metal underneath (eg. copper) the noble metal can cause the connection to fail either by managing to ooze through the pores or take advantage of the noble metal being scratched during mating.
Uses - Communications & Radio Controlled Equipment:-
Contralube will weather proof your communications connections. 'But surely it will effect the signal?'….I hear you say. You can load up your electrical and non-electrical connectors with Contralube and it will not interfere with the current flow or in the case of an analogue or digital signal, it will not degrade the signal quality.
Although the 'Why Contralube' information sheet mainly talks about electrical connectors, the same theory applies to non-electrical connections and its excellent background knowledge.
It is also ideal for your external antennae connections, it acts as a barrier/environmental seal against all things nasty that would harm the quality of the signal. From CB aerials to satellite comms terminations, this is a product you can rely on.
Radio controlled models are exposed to the elements; models using small two stroke engines also experience high levels of vibration. It is just the ticket to keep your model aeroplane, helicopter, boat or car in good working order.
Uses - Vehicle Electrics:-
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.
Our state of the art grease can protect all your connections – multipin, spade contacts, battery connections, external antennae connections; pretty much everything electro/mechanical. It is compatible with all metals (including gold and silver) and is compatible with most plastics so there is no need to worry.
Contralube is primarily an electrical contact grease but it can be used for loads of different jobs. A run through some of the many automotive applications...
Electrical connections (multi-pin, bullet, spade etc), automotive bulb 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 your wiring – engine management type warning lights or ABS 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 maybe moisture finding its way in to your equipment – a small application would stop all this hassle and is more of a permanent solution than a solvent spray lubricants. Contralube is a big favourite in the classic car market for just this type of problem.
Whilst it 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 connector ends together at incorrect angles, mostly due to the connectors being located in hard to reach places. It also minimises the mating force required, ensuring solid connections and efficient assembly.
Uses - CCTV and Audio Visual Equipment:-
Contralube will weatherproof your CCTV connections. 'But surely it will affect the picture?' I hear you say. You can load up your electrical and non-electrical connectors with Contralube and it will not interfere with the current flow or in the case of an analogue or digital signal, it will not degrade the signal quality.
Although the Why Contralube? - PDF (130KB) information sheet mainly talks about electrical connectors, the same theory applies to non-electrical connections and its excellent background knowledge.
Ideal for external audio visual applications, access and control devices – the signal will not be degraded and the contact points/multipin connections will be environmentally sealed against all the nasty things that would harm the connection – an ideal preventative maintenance tool.

How do I use Contralube 770?
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 Contralube 770 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 Contralube 770.
How does Contralube 770 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.
I am applying Contralube 770 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 Contralube 770 may be physically bridging a gap between two separate pins/circuits it will not allow the current to pass between the pins. Contralube 770 has similar conductive properties to air, so if you do not experience arcing/shorting between pins in unlubricated connectors then the addition of Contralube 770 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 Contralube 770 before using operationally in all circumstances where extreme currents/voltages are present.
How should Contralube 770/880 be stored?
Tubes of Contralube 770 and 880 should be stored indoors with the screw cap 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 original carton along with the instruction/support information paper insert.
Contralube 770 seems to turn blue, why is that?
The product contains a UV Tracer additive incorporated into it. Contralube 770 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 Contralube 770 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 Contralube 770?
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 Contralube 770 in a component under expected operating conditions. Contralube 770 is designed for lifetime component lubrication, which often exceeds 10 years in extreme operating conditions.
What is the shelf life of your Contralube 770?
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 Contralube 770 and 880 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).
Your product data sheet does not contain the details of the product formula, why is this?
We do not want the product to be copied. We do give the Recommended Service Range (°C) but we don't give details of the specialist formula use to create the Contralube range. We are very happy to discuss the composition of the product with customers that are interested in using large or regular volumes of the products.
Is Contralube compatible with the materials in my component?
Compatibility issues are usually related to the base oil of the lubricant. The link to the table below gives a rough insight into the compatibility of Contralube 770 with some of the more common plastics and elastomers - we currently do not have a compatibility chart for Contralube 880. However, due to the variability of plastics and elastomer, it is advisable to perform a compatibility test. Submerge the material in the lubricant for more than two hours at 100°C. A lubricant-free control sample of each material should also be subjected to the same temperature at the same time. Material measurements – notably weight, dimensions, shore hardness and tensile strength – should be made before and after the test. Lubricant incompatibility can cause materials to swell, shrink, harden, soften, become more or less brittle, change colour etc. Dimensional changes of up to 5% are usually considered acceptable.
The Contralube770 Compatibility Chart - (PDF 190KB) gives a rough guide to the compatibility of it with various plastics and elastomers. There are numerous types and combinations hence that this is only a rough guide and a compatibility test is recommended.
