VOLVO EXCAVATOR PARTS MADE IN CHINA NEW EC200D 14730969 SEAL KIT SPARKLING MACHINERY
SPARKLING MACHINERY NEW EC200D 14730969 Seal Kit is a dedicated, all-in-one sealing solution exclusively designed for VOLVO EC200D crawler excavators—versatile mid-sized equipment widely used in construction, municipal engineering, and light mining projects. As a core protective component for the excavator’s hydraulic system, it covers critical areas including hydraulic cylinder rods, valve connections, and pump interfaces, forming reliable leakproof barriers. This function is essential for maintaining stable hydraulic pressure, ensuring smooth and responsive operation of core mechanisms (boom lifting, arm digging, bucket tilting), and preventing dust, debris, or moisture from contaminating internal hydraulic parts. It directly reduces the risk of hydraulic system failures, avoids unplanned downtime, and eliminates costly repairs caused by oil leaks during tasks like trench digging, material loading, and site grading.
Engineered to meet VOLVO’s original equipment standards, the seal kit maintains consistent sealing reliability even under harsh conditions: high hydraulic pressure (up to 35 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous excavator vibration. It resists oil aging and wear, providing long-lasting protection for the EC200D’s hydraulic system. Backed by strict performance verification, it guarantees uninterrupted sealing support for VOLVO EC200D excavators.
