   SPARKLING MACHINERY NEW EC220D EC220E EC250D EC250E 14718261 Seal Kit is a dedicated, all-in-one sealing solution exclusively designed for VOLVO EC220D, EC220E, EC250D, and EC250E crawler excavators—versatile mid-sized heavy-duty equipment widely used in construction, mining, and infrastructure development 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 robust leakproof barriers. This function is vital 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, bulk material loading, and site grading.

   Engineered to meet VOLVO’s original equipment standards, the seal kit maintains reliable sealing performance even under harsh conditions: high hydraulic pressure (up to 37 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/EC250D/EC250E models. Backed by strict performance verification, it guarantees uninterrupted sealing support for these VOLVO excavators.

   SPARKLING MACHINERY's new ZGAQ-00100 Hub Seal is a core sealing component specifically designed for Hyundai HL780-7A/HL7803A/R200W7 excavators, suitable for construction and mining applications. It serves to seal the hub assembly, preventing lubricant leakage and the ingress of dust, water, and other contaminants. 
   Compliant with Hyundai OEM standards (Part No.: ZGAQ-00100), this component exhibits excellent sealing performance and wear resistance, ensuring seamless compatibility with original equipment and long-term stable operational performance.

   SPARKLING MACHINERY NEW ZGAQ-02328 Taper Roller Bearing is a core rotating component for Hyundai excavators (construction/mining use). It withstands combined radial and axial loads, ensuring smooth rotation of key shaft parts. 
   Meeting Hyundai OEM standards (Part No.: ZGAQ-02328), it delivers high wear resistance and load capacity, guaranteeing seamless compatibility and long-term stable operational performance.
