VOLVO EXCAVATOR PARTS MADE IN CHINA NEW EC220D EC220E EC235D 14683841 SEAL KIT SPARKLING MACHINERY
SPARKLING MACHINERY NEW EC220D EC220E EC235D 14683841 Seal Kit is a dedicated, all-in-one sealing solution exclusively designed for VOLVO EC220D, EC220E, and EC235D crawler excavators—versatile heavy-duty equipment widely used in construction, mining, and infrastructure maintenance projects. As a core protective component for the excavators’ hydraulic systems, 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, gravel, 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 high-intensity tasks like deep excavation, 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 36 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 hydraulic systems of EC220D/EC220E/EC235D models. Backed by strict performance verification, it guarantees uninterrupted sealing support for these VOLVO excavators.
