VOLVO EXCAVATOR PARTS MADE IN CHINA NEW EC135B EC140 EC140B EC160B 14514937 SEAL KIT SPARKLING MACHINERY
SPARKLING MACHINERY NEW EC135B EC140 EC140B EC160B 14514937 Seal Kit is a dedicated, all-in-one sealing solution exclusively designed for VOLVO EC135B, EC140, EC140B, and EC160B excavators—key equipment in construction, mining, and municipal infrastructure projects. As a core protective component for the excavators’ hydraulic systems, it covers critical areas such as 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 or debris 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 operations like trench digging, material loading, and site grading.
Engineered to match 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 excavators’ hydraulic systems. Backed by strict performance verification, it guarantees uninterrupted sealing support for EC135B/EC140/EC140B/EC160B excavators.

VOLVO EXCAVATOR PARTS MADE IN CHINA NEW EC220D EC235D EC250D EC250E EC300D 14592299 RELIEF VALVE SPARKLING MACHINERY
SPARKLING MACHINERY NEW EC220D EC235D EC250D EC250E EC300D 14592299 Relief Valve is a dedicated hydraulic safety component for VOLVO EC220D/EC235D/EC250D/EC250E/EC300D crawler excavators (heavy-duty equipment for construction/mining). As the hydraulic system’s core safety guard, it precisely limits max pressure to protect pumps, cylinders, and pipelines from overload damage during rock breaking or bulk loading.
Meeting VOLVO OEM standards (part no. 14592299), it endures 34 MPa pressure, -25°C to 105°C temps, and heavy vibration. It resists oil contamination and wear, ensuring long-term reliability for the five VOLVO models, with strict testing guaranteeing compatibility and safe operation.
