1R0773 Caterpillar Hydraulic Filter | Heavy-Duty Protection for CAT Machinery

Core Features & Benefits

Precision Filtration Performance for Hydraulic Systems

• Notably, it achieves 99.9% filtration efficiency for 3μm+ particles, meeting ISO 4406 Class 10 cleanliness standards and effectively trapping wear debris, metal shavings, and sludge to prevent premature wear of hydraulic pumps, valves, and cylinders.
• Moreover, the OEM-specified multi-layer gradient filter media (CAT-equivalent quality) balances filtration precision with low pressure drop (≤0.02 Mpa), preserving hydraulic system energy efficiency and stable pressure output even under extreme heavy-duty loads.
• Additionally, its enhanced dirt-holding capacity (35% higher than standard replacement filters) extends service life to 4500-6000 operating hours, aligning with CAT’s recommended maintenance schedules for heavy machinery.

1R0773 Caterpillar Hydraulic Filter Machinery Precision Compatibility

• Precisely engineered to match CAT core machinery models, enabling seamless integration without modifications or adapters—directly replacing original CAT 1R0773 components.
• Meanwhile, its standardized thread size, precision-molded gasket, and dimensional accuracy ensure leak-free installation, eliminating unfiltered oil bypass and preserving the hydraulic system’s factory-set operational parameters.
• Even for diverse fleet applications (including CAT excavators, loaders, bulldozers, and agricultural tractors), its premium build quality guarantees full compatibility with CAT’s core machinery lineup, avoiding installation mismatches or operational disruptions.

Industrial-Grade Durability for Harsh Scenarios

• Crafted with a rugged pressure-resistant housing rated up to 35 bar (508 PSI), effectively withstanding extreme operating pressures and sudden pressure spikes common in heavy-duty hydraulic systems.
• Furthermore, it boasts a wide temperature tolerance range (-20℃ to 100℃/-4°F to 212°F), adapting to harsh cold, high-heat, or humid industrial environments without compromising filtration efficiency or structural integrity.
• Thanks to its corrosion-resistant materials, reinforced internal support skeleton, and vibration-resistant design, it maintains performance against dust, chemical exposure, and mechanical impact—preventing housing deformation or media tearing.

Easy Maintenance & User-Friendly Design

• Its spin-on design enables quick, tool-efficient replacement (completable in 15-20 minutes), directly minimizing downtime for production-critical CAT machinery.
• In addition, clear part number marking and compatibility labeling simplify inventory management and model matching, reducing procurement complexity for fleet operators and maintenance teams.
• Notably, its lightweight yet robust structure facilitates hassle-free handling during installation and replacement, even in tight equipment compartments common in heavy machinery.

Cost-Effective Premium Protection/1R0773 Caterpillar Hydraulic Filter

• As a premium alternative to original CAT filters, it delivers OEM-level performance at a more competitive price point, successfully cutting spare part procurement costs for enterprises without compromising quality.
• Simultaneously, its efficient contaminant capture extends hydraulic oil service life by 30% compared to standard filters, reducing lubricant replacement and disposal expenses.
• Overall, it protects expensive CAT hydraulic components from premature wear, lowering long-term repair costs and maximizing equipment uptime for heavy-duty operations.
