B230103000744 Rubber Hose Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

As a core hydraulic hose accessory for Sany, the B230103000744 hose adheres to the principle of drain and return oil design, ensuring uninterrupted connection to the oil tank and preventing oil splashing and air bubbles, thus avoiding pump cavitation and air intake. It is compatible with the entire range of Sany excavators, including the SY55 and SY225 models, as well as tank trucks, matching original factory dimensions for direct replacement, improving maintenance efficiency and reducing equipment downtime.
The B230103000744 hose is made of high-specification oil-resistant material and precision process. The main body is composed of a nitrile rubber inner layer, a multi-layer steel wire braided reinforcement layer, and a wear-resistant outer rubber layer. The joint is a one-piece peel-free embossed structure with a steel stamp, which provides excellent sealing to prevent leakage. It is resistant to pulse and wear aging, suitable for complex working environments, extends service life, reduces maintenance costs, and meets SANY original factory standards.
