Professional Old-Style Block Cartridge Structure
Specially designed for Bobcat 4BD4FI old-type manifold blocks with precise 46mm mounting thread. It is a direct replacement for 6679837, featuring perfect size fitment and seamless assembly without any modification.
Low Pressure Loss & Stable Hydraulic Output
Optimized smooth internal flow channel reduces fluid resistance and pressure drop. It maintains stable and consistent hydraulic power output under heavy-load operation, effectively improving the overall working efficiency of loader hydraulic attachments.
Heavy-Duty Anti-Corrosion Construction
Constructed with high-strength carbon steel and premium zinc surface treatment, the cartridge delivers excellent wear resistance, pressure resistance and corrosion resistance. It adapts to harsh construction, farm and outdoor working environments for long-term stable operation.
High Compatibility & Cost-Effective Maintenance
