B210780000052 Straight-through connector Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

As a core hydraulic connector of Sany, the B210780000052 adheres to the standard for direct-connection of drain and return oil, adopting a high-strength integrated structure and a precision internal sealing design to ensure a secure and leak-free pipeline connection, preventing oil splashing and cavitation. It is widely compatible with all Sany series medium and large excavators, matching original factory installation dimensions for direct replacement, significantly improving maintenance efficiency and reducing equipment downtime.
The product uses high-specification materials and precision machining processes. The main body is made of high-quality carbon steel with a galvanized anti-rust treatment, providing excellent resistance to pulse, wear, and aging, making it suitable for the complex and harsh operating environments of construction machinery. The connector has a built-in high-precision sealing component with dual metal and rubber sealing, providing excellent pressure resistance and preventing loosening and leakage even after long-term use, strictly complying with SANY’s original technical specifications.
