What is TKPS-1 lubricant and why is it needed?
Conductive preservative grease is a multi-component material based on mineral oils thickened with lithium soap, with the addition of dispersed graphite and copper powder. It is the presence of metal and carbon particles that provides the composition with the ability to conduct electric current, while the oil base acts as a preservative. Unlike dielectric lubricants, which isolate the contact from the external environment, but do not participate in the transmission of current, TKPS-1 is actively included in the electrical circuit, reducing the transition resistance.
The main purpose of this product is to provide reliable electrical contact in low voltage DC and AC circuits. TKPS lubricant prevents sparking, overheating and welding of contact surfaces, which is especially important for units with high current load. In addition, it effectively protects metal parts from corrosion caused by stray currents and exposure to an aggressive external environment.
⚠️ Attention: Despite the conductive properties, TKPS-1 cannot be used to lubricate contacts of high-voltage ignition systems (plug tips, coils), as this can lead to breakdowns and unstable engine operation.
Application conductive lubricant justified in places where not only protection against oxidation is required, but also improvement of the conductivity of an existing connection. These can be massive power contacts, grounding buses, connections of starters and generators. A properly applied layer of material is able to work in a wide range of temperatures, maintaining its properties even under extreme loads.
Key technical characteristics and composition
Understanding the question of where buy conductive grease, it is important to understand what parameters make TKPS-1 unique.

Instructions: how to apply lubricant correctly
To achieve maximum effect from use conductive preservative grease it is necessary to strictly follow the technology of its application. The process begins with thorough surface preparation: contacts must be cleaned of dirt, old grease, oxides and corrosion. For cleaning, you can use a wire brush, sandpaper, or special contact cleaner sprays.
After mechanical cleaning of the surface, it is recommended to degrease them with solvent or alcohol. This will ensure better adhesion TKPS-1 to metal. The lubricant is applied in a thin, even layer to both contacting surfaces. Do not apply too thick a layer, as this may lead to excess squeezing out when tightening the connection and contamination of surrounding parts.
Sequence of actions:1. Turn off the power source.
2. Clean the contacts to a metallic shine.
3. Degrease surfaces.
4. Apply a layer of TKPS-1 with a brush or spatula.
5. Connect the parts and tighten the fasteners.
6. Remove any excess that appears.
After connecting the parts and tightening the fasteners, excess lubricant that has come out should be carefully removed with a rag. This will prevent the adhesion of dust and dirt, which over time can turn into an abrasive paste. Conductive Grease inside the connection will remain functional for decades if the installation was done correctly.
☑️ Application quality control
Where to buy TKPS-1 and how to distinguish the original
The question is where buy conductive grease TKPS-1 is becoming relevant for many car enthusiasts and specialists. The products are produced in metal cans of various sizes, as well as in tubes and syringes for more convenient dosed application. It is best to purchase material in specialized auto parts stores, radio parts stores, or from official dealers of industrial lubricants.
The market is full of analogues and counterfeits, so it is important to pay attention to packaging and labeling. Original TKPS-1 has a specific dark brown, almost black color and a homogeneous paste-like structure without foreign inclusions. The label must indicate GOST or TU, production date, expiration date and contact details of the manufacturer.
When purchasing through online platforms, you should beware of offers with a suspiciously low price. A quality product cannot be cheap due to the cost of raw materials (copper, graphite) and production technology. Conductive Grease low quality may contain cheap graphite in excess instead of copper powder or even be simply a bitumen composition, which will not give the desired effect.
⚠️ Attention: Avoid buying lubricants by weight without the original packaging - dust, moisture and metal shavings could get into such a product, which will make its use dangerous for electronics.
Trusted suppliers can always provide a quality certificate for a batch of goods. If you are planning buy conductive grease for regular use in a car service, it makes sense to consider wholesale purchases from manufacturers, which guarantees the freshness of the product and the authenticity of its origin.
Why might the price differ?
The price of TKPS-1 depends on the volume of containers, type of packaging (bucket, jar, tube) and logistics costs. Wholesale quantities are always cheaper than retail, and products in aerosol cans will cost more due to the cost of the sprayer.
Comparison with analogues and substitutes
There are many products on the market that are marketed as conductive lubricants, however TKPS-1 occupies a special niche due to its classic composition. It is often compared to graphite lubricants such as USsA, but the latter lacks the copper component, which makes them less effective for power contacts with high currents.
There are also foreign-made honey-containing pastes (for example, Permatex, Liqui Moly), which are often much more expensive. They may have improved temperature characteristics or special additives, but for standard automotive electrical service tasks TKPS-1 often turns out to be more than sufficient in its properties.
It's important not to confuse conductive lubricants with dielectric. The latter are used to isolate contacts from moisture (for example, in spark plug wells or headlight connectors), but they do not conduct current. Using a dielectric instead of TKPS on the power terminals will result in poor contact and overheating.
- 🥇 TKPS-1: Classic composition, optimal price-quality ratio, time-tested formula.
- 🥈 Foreign copper pastes: They often have a wider temperature range, but are significantly more expensive.
- 🥉 Graphite lubricants: Cheaper, but inferior in conductivity at high currents and less resistant to washout.
Choosing between the original TKPS and an expensive imported analogue, specific operating conditions should be assessed. For an ordinary car parked in a garage or on the street, a domestic product copes with the task no worse than famous brands.
The main difference between TKPS-1 and its competitors is its balanced composition, tailored to the operating conditions in the post-Soviet space and an affordable price without loss of quality.
Frequently asked questions (FAQ)
Is it possible to use TKPS-1 to lubricate contacts in high-frequency electronics?
No, conductive lubricant TKPS-1 Designed primarily for low-voltage DC and AC circuits with relatively low frequencies.
