KOMATSU EXCAVATOR PARTS MADE IN CHINA NEW 0501.206.521 JOINT DOUBLE SPARKLING MACHINERY
SPARKLING MACHINERY NEW 0501.206.521 Joint Double is a dedicated hydraulic connection component for Komatsu excavators (widely used in construction, mining, and infrastructure projects). As the "hydraulic pipeline linker", it connects two hydraulic tubes to ensure smooth, leak-free oil flow between system components—supporting key functions like boom lifting, bucket digging, and swing movements, while adapting to the excavator’s operational vibration and spatial layout.
Meeting Komatsu OEM standards (part no. 0501.206.521), it endures 30 MPa working pressure, -30°C to 95°C temperatures, resists hydraulic oil corrosion and wear, and maintains tight connection performance. Strict testing guarantees seamless compatibility with applicable Komatsu models and long-term hydraulic system stability.
