Basic Parameters & Introduction
This premium genuine High-Pressure Hydraulic Hose Assembly features the Hitachi part number 4269807. As a high-end, heavy-duty fluid transmission unit, it is deeply engineered for Hitachi new-generation ZAXIS-7 series medium-to-large hydraulic excavators, accurately matching the Hitachi ZX300LC-7 and ZX300LCN-7 30-ton class flagship models. Based on first principles, it is constructed from multi-layer high-tensile steel wire braided reinforcement and an anti-impulse, wear-resistant special synthetic rubber compound. It seamlessly withstands ultra-high operating pressures and sudden alternating pressure impulses during main pump or control阀 direction shifts, ensuring absolute deterministic power transfer. The product packaging physical dimensions are approximately 650mm × 120mm × 60mm, with a net weight of around 2.15kg.

Maintenance Tips
"Daily Inspection (Every 10 Hours / Shift): Before each shift, a mandatory visual check of the entire hose length must be conducted. Inspect for any outer rubber abrasion, exposed steel wire, abnormal localized bulging, or fitting seepage to eliminate sudden burst blind spots.

Anti-Wear Verification (Every 250 Hours): Every 250 working hours, inspect the tightness of hose clamps and protective spring sleeves, thoroughly clearing away any black-box hard rubbing friction between hoses or against the chassis frame induced by high-frequency physical vibration.

Safety Preventive Replacement (Every 4000 Hours / 2 Years): Hose materials undergo irreversible thermodynamic aging. Regardless of visual condition, this core high-pressure hose must be rigidly and forcefully replaced at a maximum of 4000 hours (or 2 years) to completely eliminate high-pressure blowout risks."

Installation Tips
"Absolute Pressure Release & Fluid Dustproofing (Core Pitfall Avoidance): Before replacement, rigidly shut down the engine, cycle all joysticks 5–10 times to fully vent pilot accumulator pressure, and slowly open the hydraulic tank cap to vent residual physical air pressure. Upon disconnecting, immediately seal the ports with dedicated dust plugs to prevent external hard particles from entering the core hydraulic circuit.

Natural Streamline & Anti-Axial Torsion: When mounting the new hose, ensure it maintains a naturally smooth, curved streamline path. It is strictly forbidden to subject the hose to rigid axial torsion or forced stretching (use the layout line printed on the hose surface as a physical reference to ensure it stays perfectly parallel during tightening). Pressurizing a twisted hose triggers local wire stress concentration, leading to a lightning-fast blowout."
