SPARKLING O Ring Kit Box – Durable Excavator Sealing Solutions

The Caterpillar O‑Ring Kit (part no. 270‑1528 / 2701528) includes approximately 570 nitrile (Buna‑N) O‑rings available in 32 standard sizes, designed for use in heavy-duty Cat equipment such as wheel loaders (962, 936F, 960F, 972G, 980C, 980F) and excavators. Built to OEM specifications with 90 Durometer hardness, this kit offers reliable sealing for hydraulic fittings (SAE STOR, ORFS, Code 61/62 flanges), preventing leaks, maintaining system integrity, and significantly reducing downtime during maintenance

   SPARKLING MACHINERY NEW EC250D EC290B EC290C 14616531 Solenoid Valve is a premium China-made hydraulic control component specifically engineered for EC250D, EC290B, and EC290C excavators. As a critical part of the hydraulic and electrical system interface, it uses electromagnetic signals to control fluid flow direction, pressure, and flow rate, enabling precise activation of hydraulic actuators such as cylinders and motors during operational tasks.

   Designed to original equipment standards, it maintains rapid response times and stable switching performance even under continuous electrical and hydraulic stress. With optimized valve body design for minimal pressure loss, it adapts seamlessly to harsh working environments, from dusty construction sites to wet conditions. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW EC140 EC160 EC180 EC200 EC210 7270-30150(14676548) Relief Valve is a vital hydraulic safety component for Volvo EC140, EC160, EC180, EC200, and EC210 excavators (widely used in construction, municipal engineering, and light mining). As the "hydraulic pressure safety buffer", it automatically releases excess pressure from hydraulic circuits during tasks like digging, boom adjustment, and material handling—preventing overpressure damage to pumps, valves, and cylinders, while ensuring stable pressure output for smooth equipment operation.
   Meeting Volvo OEM standards (part nos. 7270-30150/14676548), it endures -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and guarantees precise pressure relief triggering. Strict testing ensures seamless compatibility with the five Volvo models and long-term hydraulic system safety.

   SPARKLING MACHINERY NEW R1200-9 R140LC9 R140W9 R145CR9 R160LC9 R170W9 72Q6-02120 Door Lock Assy is a dedicated cab safety component for Hyundai R1200-9, R140LC9, R140W9, R145CR9, R160LC9, and R170W9 excavators (widely used in construction, mining, and municipal engineering). As the "cab security core", it secures the excavator cab door—preventing unauthorized access, blocking dust/debris from entering the cab, and ensuring operator safety during high-intensity tasks like digging, lifting, and rock breaking, while withstanding vibration and harsh on-site conditions.
   Meeting Hyundai OEM standards (part no. 72Q6-02120), it endures -30°C to 85°C temperatures, resists corrosion and impact, and maintains stable locking performance. Strict testing guarantees seamless compatibility with the six Hyundai models and long-term cab security.
