SPARKLING OEM Hyundai Oil Cooler Plate-Fin – Reliable Excavator Part

The Hydraulic Oil Cooler Assembly (part no. 11M8‑40032 / 11M8‑43120) is a high-efficiency, all‑aluminum plate‑fin heat exchanger engineered for Hyundai compact excavators—specifically R55‑7 and R55W‑7 (also fitting R60‑7). Built free of epoxy, this OEM‑spec cooler ensures optimal heat dissipation and withstands continuous high pressure (up to 2 MPa), making it a reliable drop‑in replacement for demanding operation environments

   SPARKLING MACHINERY NEW ND116420-7450 Heater Rad Set is a core climate control assembly for Komatsu D155AX/D65EX/D65PX/HB205/HB215 excavators (construction/mining use). It integrates a heater radiator and matching components, heating cabin air via engine coolant circulation to ensure comfortable and safe operation in low temperatures. 
   Meeting Komatsu OEM standards (ND116420-7450), it resists -30°C to 120°C temps, corrosion, and coolant contamination, guaranteeing seamless compatibility and reliable long-term heating performance.

   SPARKLING MACHINERY NEW 1221E 1221F E131-0256 Valve Bypass is a dedicated hydraulic flow control component for Volvo 1221E, 1221F crawler excavators (widely used in construction, municipal engineering, and medium-scale earthmoving). As a core part of the excavator’s hydraulic system, it diverts excess hydraulic oil to the tank or secondary circuits when primary functions are idle—preventing pressure buildup, reducing energy waste, and ensuring smooth operation during tasks like digging, loading, and boom positioning.
   Meeting Volvo OEM standards (part no. E131-0256), it endures 28 MPa working pressure, -30°C to 90°C temperatures, resists oil corrosion and vibration, and maintains leak-free flow control. Strict testing guarantees seamless compatibility with Volvo 1221E/1221F and long-term hydraulic system efficiency.

   SPARKLING MACHINERY NEW EC330B EC360B VOE14612629 Cable Harness is a premium China-made electrical connection component specifically engineered for EC330B and EC360B excavators. As a critical part of the machinery’s electrical system, it organizes and transmits electrical signals between key components—such as sensors, controllers, and actuators—ensuring seamless communication for functions like engine control, hydraulic system operation, and cabin electronics.

   Designed to original equipment standards, it maintains stable signal transmission even under harsh working conditions, including vibration, temperature fluctuations, and exposure to dust or moisture. With optimized wire routing and secure connector design, it prevents signal interference and reduces the risk of electrical failures. Backed by strict quality verification, it guarantees reliable performance to support uninterrupted machinery operation, minimizing downtime caused by electrical issues.
