DEPA.TG68 Precision Rail Oil - High-Performance Hydraulic Oil from China Suppliers & Factory
Advantages
- Very long service life.
- Excellent anti-scuffing property gives special protection even when high speed, high pressure and high temperature conditions are encountered.
- Excellent corrosion and rust prevention.
- Good demulsibility promotes quicker water separation. If water is an unavoidable contaminant, this advantage effectively retains lubrication.
- Anti-foam additive allows any entrained air to be released and burst quickly, ensuring enough lubrication between machine parts at any time.

Frequently Asked Questions
Q
What viscosity grade should I choose for my equipment?
The right viscosity grade depends on your equipment's operating temperature and manufacturer recommendations. TG32 and TG46 are suitable for lighter-duty or lower-temperature applications, while TG68 and TG100 are better suited for heavier loads and higher operating temperatures. Always refer to your equipment manual for the specified ISO viscosity grade.
Q
How does the anti-scuffing property protect my machinery?
The anti-scuffing additive forms a protective film on metal surfaces, preventing direct metal-to-metal contact under extreme pressure, high speed, and elevated temperature conditions. This significantly reduces wear and extends the service life of gears, bearings, and other critical components.
Q
What happens if water enters the lubrication system?
Thanks to the excellent demulsibility of this oil, water separates quickly from the lubricant rather than forming a stable emulsion. This means the oil retains its lubricating performance even when water contamination is unavoidable, protecting your equipment from corrosion and wear.
Q
Why is the flash point important, and what are the values for each grade?
The flash point indicates the minimum temperature at which the oil can produce ignitable vapors, making it a key safety parameter. TG32 has a flash point of 215°C, while TG46, TG68, and TG100 all reach 250–260°C, providing a wide safety margin for most industrial operating environments.
Q
How does the anti-foam additive benefit my system?
Foam in a lubrication system can cause oil starvation, increased oxidation, and poor heat dissipation. The anti-foam additive allows entrained air bubbles to collapse and release quickly, maintaining a consistent oil film between moving parts and ensuring reliable lubrication at all times.
Q
What is the pour point, and why does it matter for cold-weather operation?
The pour point is the lowest temperature at which the oil remains fluid enough to flow. TG32 has the lowest pour point at -20°C, making it the best choice for cold-start or low-temperature environments. TG100 has a pour point of -10°C and is more suited to warmer operating conditions.
