14030851 Oil drain pipe connector Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

As a key connecting component of Sany’s drain and return oil system, the 14030851 drain pipe connector adheres to pipeline connection standards and adopts an optimized structure adapted to the working conditions of construction machinery. It can precisely match the connection requirements of different pipe specifications, achieving seamless connection, ensuring smooth oil transmission, strengthening sealing protection, and avoiding system failures and environmental pollution caused by connection failures. It is compatible with the entire range of Sany SY200, SY245, and other medium and large excavators, matching original factory dimensions and interfaces, allowing for direct replacement, improving maintenance efficiency, and reducing downtime losses.
The 14030851 drain pipe connector uses high-specification materials and precision manufacturing processes. The main body is made of high-quality carbon steel with galvanized anti-rust coating, which is rigid, has excellent pressure resistance, impact resistance, wear resistance and aging resistance, and avoids corrosion at the connection. It has a built-in metal + nitrile rubber double sealing component, which fits the 24° conical sealing design, is resistant to oil corrosion, has a tight seal, is suitable for complex working conditions, is not easy to rust and leak, can withstand vibration and oil erosion for a long time, reduces operation and maintenance costs, and complies with SANY original factory specifications and GB/T 14034.1-2023 standard.
