Specifications
Superior Anti-Wear (AW) Performance:
Packed with advanced zinc-based anti-wear additives that shield high-pressure pumps (vane, piston, and gear pumps) from severe friction and scuffing.
Excellent Viscosity-Temperature Stability:
Minimizes fluid thinning under intense heat, ensuring stable operating pressure and preventing internal systemic leakage.
Outstanding Demulsibility (Water Separation):
Rapidly separates from water, preventing emulsification and safeguarding internal components against rust and cavitation.
High Oxidation & Thermal Resistance:
Resists oil degradation, sludge, and varnish formation at high operating temperatures, significantly extending oil drain intervals.
Superior Air Release & Foam Control:
Rapidly releases entrained air to eliminate sponginess in controls, ensuring precise hydraulic responses and preventing pump cavitation damage.
🏗️ System Applications & Machine Years
Universal Compatibility: Suitable for heavy machinery manufactured across all years (from retro legacy models up to current 2026 models), provided the OEM manual specifies an ISO VG 68 (L-HM 68) hydraulic fluid.
Note: HM 68 is the heavy-duty industry standard for high-temperature climates and heavy-load systems.
Shantui Heavy Equipment: Hydraulic systems for bulldozers (SD16, SD22, SD32), wheel loaders, and road rollers operating in hot environments.
Komatsu Excavators: Main hydraulic circuits for medium-to-large excavators (PC200, PC300, PC360, PC450 series) operating in tropical, subtropical, or high-load summer conditions.
Industrial & Mining Applications: Heavy-duty hydraulic presses, injection molding machines, die-casting equipment, mining conveyors, and marine deck machinery.
