B210780000838 Right Angle Combination Connector Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

As a core hydraulic connector of Sany, the B210780000838 adheres to the original factory connection standard, precisely achieving a 90° rotation. One end is an external thread interface, which can be directly connected to the equipment valve body; the other end, with a rotating nut and clamping structure, achieves a tight seal on the steel pipe, adapting to different pipe diameters. Installation is convenient and seamless, effectively preventing oil leakage and pipe loosening, and improving system operational stability. It is compatible with all Sany excavators, pump trucks, and tank trucks, matching the original factory installation dimensions, allowing for direct replacement, significantly shortening maintenance time and reducing equipment downtime losses.
The B210780000838 uses high-specification materials and precision machining processes. The main body is made of high-quality carbon steel with a galvanized anti-rust treatment, making it resistant to pulse and wear aging, and suitable for the complex and harsh working conditions of engineering machinery. Its combined sealing structure integrates metal and rubber double seals, providing excellent pressure resistance and maintaining a near-zero leakage seal under high pressure, extending service life, reducing maintenance costs, and fully complying with SANY original equipment manufacturer (OEM) specifications.
