Dedicated Old-Style Block Matching Structure
Specially engineered for Bobcat 4BD4FI old-type manifold blocks with precise 46mm mounting thread. It achieves seamless assembly with 6680018 female coupler, serving as the original standard male cartridge for early Bobcat hydraulic systems without any modification.
Optimized Flow Channel & Stable Hydraulic Output
Internal smooth flow channel minimizes fluid resistance and pressure drop. It maintains stable and consistent hydraulic power output under long-term heavy-load operation, effectively improving the working efficiency of various hydraulic attachments.
Heavy-Duty Wear & Corrosion Resistance
Constructed with high-strength carbon steel and premium zinc surface treatment, the male cartridge features excellent pressure resistance, wear resistance and environmental adaptability. It stably copes with harsh construction, farm and outdoor working conditions for long-term service.
Modular Design & Low Maintenance Cost
Independent modular cartridge structure supports single-part replacement, avoiding overall manifold block replacement and greatly reducing equipment maintenance costs. One-hand tool-free quick connect design realizes fast switching of hydraulic attachments with high universal interchangeability.
