The P557380 Hydraulic Filter is a premium-grade, heavy-duty filtration element engineered to protect high-pressure hydraulic systems in demanding industrial and construction machinery. It serves as a direct, high-quality replacement for original OEM parts, specifically designed for Komatsu bulldozers/excavators and Shantui heavy machinery.

Featuring a robust, precision-engineered perforated metal support structure and advanced high-precision filtration media, the P557380 is built to withstand significant pressure differentials and sudden hydraulic fluid surges without collapsing or sacrificing flow rates. It effectively captures damaging metallic wear particles, silica contaminants, silt, and sludge that can cause premature wear on sensitive hydraulic pumps, cylinders, and control valves. By maintaining fluid purity, this filter ensures ultra-smooth operation, reliable system response, and maximum uptime for heavy-duty fleets.

As a trusted global commercial filtration supplier, we provide P557380 hydraulic filters manufactured to strict OEM standards to ensure a flawless fit, long-term operational reliability, and maximum protection for your heavy equipment investments.

Please verify the precise technical dimensions and primary application details below to ensure exact compatibility with your system:

The P557380 hydraulic filter is equivalent to and can directly replace the following OEM and aftermarket part numbers:

• High-Pressure Resistance Structure: Built with a reinforced heavy-duty inner core and a thickened sealing end-face, this filter easily tolerates instantaneous flow fluctuations and pressure drops within heavy-duty hydraulic circuits.
• Micron-Level System Protection: Precisely captures fine metallic particles and airborne dust invisible to the naked eye, safeguarding high-precision hydraulic control valves and pumps from friction wear.
• Premium Mechanical Strength: The robust external and internal perforated metal cages prevent media bunching and pleat collapse under high oil viscosity and low-temperature startup conditions.
• Extended Fleet Service Life: High dirt-holding capacity media construction significantly reduces clogging frequency, lowering overall maintenance costs and safely extending service intervals.

This filter is highly compatible with a wide array of earthmoving equipment, large bulldozers, crawler loaders, and hydraulic excavators:
