SPARKLING Cat 962 O-Rings – Durable Excavator Seal Parts

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 HW140 R140W9 R140W9A XJDD-01270 Seal Kit is a dedicated sealing component set for HYUNDAI HW140, R140W9, and R140W9A wheeled excavators (versatile for road construction, municipal engineering, and material handling). As a key part of the excavator’s hydraulic and engine systems, it seals gaps between components (e.g., hydraulic cylinders, engine covers) to prevent oil leaks, dust intrusion, and fluid contamination—ensuring stable operation during tasks like digging, loading, and road grading.
   Meeting HYUNDAI OEM standards (part no. XJDD-01270), it endures -30°C to 100°C temperatures, resists hydraulic oil corrosion and mechanical wear, and maintains tight sealing performance. Strict testing guarantees seamless compatibility and long-term reliability for the three HYUNDAI models.

   SPARKLING MACHINERY NEW 416E 416F 420F 422E 422F 428E 350-8841 Kit-Compensa is a dedicated hydraulic compensation component kit for Caterpillar 416E, 416F, 420F, 422E, 422F, and 428E backhoe loaders/excavators (widely used in construction, municipal engineering, and agricultural operations). As a key set for the equipment’s hydraulic system, it maintains stable pressure and flow compensation during multi-function operations (e.g., simultaneous boom lifting and bucket digging), ensuring smooth, coordinated control of hydraulic functions to avoid performance lag.
   Meeting Caterpillar OEM standards (part no. 350-8841), it endures 28 MPa hydraulic pressure, -30°C to 90°C temperatures, resists oil corrosion and vibration, and guarantees consistent compensation performance. Strict testing ensures seamless compatibility with the six Caterpillar models and long-term hydraulic system stability.

The 709-63-11501 / 709-63-11600 Control Valve Assembly is a precision-engineered hydraulic component specifically designed for Komatsu D375A series bulldozers. As a key part of the machine’s hydraulic system, this valve ensures smooth, accurate, and responsive blade and ripper control—essential for productivity in high-demand mining, earthmoving, and large-scale construction environments.

Manufactured with robust materials and OEM-level quality control, our replacement control valve delivers stable pressure regulation, excellent sealing performance, and long service life, even under continuous heavy-duty operation.
