21051021 Tee Combination Connector Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

As a key connecting component of Sany’s oil return system, the 21051021 tee combination joint strictly adheres to the pipeline connection standards for oil return systems. It adopts an integrated structure, combining the tee body and sealing components, precisely matching the connection requirements of the main and branch pipelines for oil return. This enables efficient oil diversion and merging, changes the oil flow direction, simplifies pipeline layout, and provides excellent sealing performance, effectively preventing oil leakage and avoiding hydraulic system pressure loss and component damage due to connection failure. It is compatible with the entire range of Sany SY200, SY245, and SY425 medium and large excavators, matching original factory mounting dimensions and thread specifications, allowing for direct replacement, improving maintenance efficiency, and reducing equipment downtime.
The 21051021 tee combination joint is made of high-specification materials and precision machining. The main body is made of high-quality carbon steel with a galvanized anti-rust treatment. It has high rigidity, excellent pressure resistance, and is resistant to impact, wear, and aging. It has a built-in metal + nitrile rubber double sealing component, which is tight and resistant to oil corrosion. It is suitable for the complex and harsh operating environment of engineering machinery. It is not easy to rust or leak. It can withstand the impact of equipment vibration and oil erosion for a long time, extending its service life and reducing maintenance costs. It fully complies with SANY original factory specifications and relevant industry standards GB/T 12459-2017.

Core technical parameters:

– Part number: 21051021
– Fitting type: T-shaped combination fitting, which can realize oil diversion and merging, and integrates the tee body and sealing components.
– Compatible models: Sany SY200/SY245/SY425 and other full series of medium and large excavators and Sany tank trucks.
– Operating pressure: ≤35MPa (pressure resistance test ≥50MPa), suitable for low-pressure transmission requirements of oil return and drainage systems, ensuring smooth and unobstructed flow.
– Structural parameters: T-type tee combination structure, equal diameter interface design, built-in double sealing components, tight connection, and flexible realization of pipeline branching and merging.
– Material Specifications: Main body is made of high-quality carbon steel with galvanized anti-rust treatment; sealing components are made of metal and nitrile rubber, which are oil-resistant, wear-resistant, and anti-aging.
– Compatibility: Suitable for connecting the main and branch pipes of Sany’s drain and return oil system, used for oil diversion and merging, matching original equipment manufacturer (OEM) piping specifications.
– Installation method: Threaded connection, the interface thread precisely matches the original, making installation convenient and secure, and able to withstand high-frequency vibrations from the equipment.
– Execution Standard: Complies with SANY original factory specifications, GB/T 12459-2017 and relevant standards for hydraulic fittings, and has passed pressure and sealing tests.

Compared to ordinary tee fittings, the 21051021 tee combination fitting conforms to SANY’s original factory standards, with optimized combination structure and sealing technology. It integrates the tee body and sealing components, eliminating the need for additional sealing accessories, making installation more convenient. At the same time, it ensures smooth flow and tighter sealing, accurately realizing oil diversion and merging, simplifying pipeline layout, adapting to high-frequency vibration operation scenarios of construction machinery, effectively preventing oil leakage, protecting the stable operation of the oil return system, and improving equipment operating efficiency and service life.
