Technical Information and Features

Based on Restoreplus Proplus HD-68, here are the common technical values of equivalent products in this segment:

• Advanced Friction Management: Contains special friction modifiers for clutch discs and wet brake systems in powershift transmissions. Prevents Clutch Slippage and minimizes brake noise (chatter).

• High Load-Carrying Capacity: Forms a strong Oil Film that prevents metal-to-metal contact in the final drive and differential gears of construction machinery.

• Wear and Corrosion Protection: Prevents wear in high-pressure hydraulic pumps and sensitive valves. Protects internal components against rust Like a Molecular Shield.

• Thermal Stability: Maintains viscosity even at very high operating temperatures. Prevents oxidation of the oil and Sludge/Residue Formation inside the system.

• Air Release and Foam Control: Quickly suppresses foaming to prevent power losses and Cavitation Damage; ensures quieter system operation.

• Seal Compatibility: Fully Compatible with advanced sealing elements (elastomers) used by manufacturers like Caterpillar, Komatsu, and Volvo; prevents oil leaks.

• Specification Compliance: Meets industrial heavy-duty standards such as Caterpillar TO-4, Allison C-4, and ZF TE-ML 03C.

• Long Service Life: Extends Oil Change Intervals even under demanding construction and mining conditions, thanks to advanced base oil and additive technology.

Application Area: This product is especially used safely in the powershift transmissions, differentials, final drive units, and high-load hydraulic systems of giant construction machinery such as Caterpillar and Komatsu.
