   SPARKLING MACHINERY NEW EC135B EC160C EC235D EC290C 960259 O-Ring is a dedicated sealing component exclusively designed for VOLVO EC135B, EC160C, EC235D, and EC290C excavators—key equipment in construction, mining, and infrastructure maintenance. As a critical part of the excavators’ hydraulic, fuel, and coolant systems, it creates tight, leakproof seals between mating components (e.g., hydraulic valve connections, fuel line joints, and coolant hose interfaces). This function is essential for maintaining system pressure stability, preventing fluid leakage (hydraulic oil, fuel, coolant), and blocking dust or debris from entering internal mechanisms. It directly reduces the risk of system failures, avoids unplanned downtime, and eliminates costly repairs caused by leaks during high-intensity operations like digging, heavy material handling, or site grading.

   Engineered to match VOLVO’s original equipment standards, the O-ring maintains reliable sealing performance even under harsh conditions: high pressure (up to 30 MPa), extreme temperature fluctuations (-30°C to 110°C), and continuous excavator vibration. It resists fluid aging and material degradation, ensuring long-lasting protection for the excavators’ key systems. Backed by strict performance verification, it guarantees consistent sealing support for EC135B/EC160C/EC235D/EC290C excavators.

   SPARKLING MACHINERY NEW 8-98238255-2 EGR Valve is a premium China-made emissions control component designed for compatible diesel-powered construction machinery (such as excavators, loaders) and industrial engines. As a core part of the Exhaust Gas Recirculation (EGR) system, it precisely regulates the flow of exhaust gas back into the engine’s intake manifold—reducing the combustion temperature to minimize the formation of nitrogen oxides (NOx), a major harmful emission. This ensures compliance with global emission standards (e.g., Tier 4 Final, Euro V) while maintaining engine power output for heavy-duty tasks like digging, lifting, and material handling in construction, mining, and urban infrastructure projects.

   Engineered to original equipment standards, it maintains reliable performance even under harsh working conditions, including high exhaust temperatures (up to 650°C), vibration, and exposure to soot or exhaust contaminants. With a precision-machined valve stem and adaptive sealing design, it minimizes gas leakage and ensures smooth, responsive flow control. Backed by strict quality verification, it guarantees consistent emissions reduction and prevents EGR system-related engine issues, supporting uninterrupted machinery operation.
