Core Performance Features
Standardized Universal Design: Integrated spin-on structure, tool-free quick replacement, seamless direct replacement for multi-brand filters of the same specifications, compatible with most universal filter heads, extremely low installation and maintenance costs.

High Dirt-Holding Capacity & Long-Term Protection: Optimized folded filter media structure with high dirt-holding capacity, efficiently capturing metal wear debris, solid particles, and gelatinous contaminants in oil, significantly extending the service life of hydraulic system components.

High Reliability & Operational Adaptability: High-strength metal housing + built-in bypass valve design, resistant to hydraulic shock, equipment vibration, and extreme temperature fluctuations. The bypass valve opens when the filter is clogged to ensure continuous oil supply, preventing flow interruption and equipment damage, suitable for complex conditions such as outdoor mining and construction sites.

Full Range of Precision Options: Same size and structure available in full gradient precision models, selectable as needed: P161553 (2μm), P161551 (10μm), P161552 (25μm).

Core compatible application scenarios
Core compatible equipment: Hydraulic systems, power shift transmissions, and drivetrain oil filtration for Caterpillar (CAT) series excavators, loaders, bulldozers, motor graders, generator sets, and agricultural machinery.
General application scenarios: Purification and filtration of medium-low pressure hydraulic circuits, lubricating oil circuits, and gear oil systems in industrial hydraulic stations, injection molding machines, mining machinery, marine auxiliary engines, and sanitation equipment.
