21051021 Tee Combination Connector Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The Sany 21051021 tee connector, custom-designed for Sany construction machinery, is a core component for hydraulic pipeline diversion and conversion. Precision forged from high-standard alloy structural steel, it adheres to original equipment manufacturer (OEM) standards and is compatible with Sany excavators, crawler cranes, and other equipment. It enables efficient diversion and merging of hydraulic oil and pneumatic transmission media, withstands high pressure and heavy loads, and is suitable for mining, infrastructure, and other applications. It prevents pipeline leakage and cracking, making it the preferred choice for hydraulic system maintenance and replacement, and for new machine integration.
As a dedicated tee connector for SANY products, this product enjoys widespread trust due to its superior materials and precision manufacturing process. Its core function is to precisely connect three pipelines, achieve media diversion, simplify pipeline setup, facilitate maintenance, avoid redundant splicing failures, reduce hydraulic system risks, adapt to harsh environments such as dust and high/low temperatures, extend component life, and is compatible with mainstream SANY models such as the SY55 and SY75. This product complies with ISO/TS 16949 and GB/T 12459-2005 standards, has the same quality as the original manufacturer, is directly replaceable, and its integrated compression fitting structure eliminates the need for additional sealing, making disassembly and assembly convenient and ensuring continuous equipment operation.

【Core Technical Parameters】

-Part number: Sany 21051021
– Compatible models: Sany excavators and engineering vehicles (with a focus on mainstream models such as SY55, SY75, and SY215, covering various construction scenarios)
– Compatibility Specifications: Precisely matches the original hydraulic system dimensions, fits the installation position perfectly, does not affect flow or pressure, and is compatible with original hydraulic hoses and seamless high-pressure steel pipes.
– Material and Craftsmanship: High-standard alloy structural steel, multiple layers of anti-rust and anti-corrosion treatment, integrated forging and precision CNC machining, conforming to GB/T 12459-2005 standard, corrosion-resistant and pressure-resistant, with a service life far exceeding that of non-standard joints.
– Size parameters: The interface is compatible with metric standards, and the body and holes fit the original factory specifications without modification. The size can be customized as needed (standard sizes can be matched with the original factory specifications).
– Pressure resistance: Rated working pressure 31.5MPa, instantaneous peak pressure 42MPa, can withstand high pressure impact without leakage or rupture, meets industry standards.
– Operating temperature: -40℃～+120℃, suitable for high and low temperature environments, no sealing hardening or leakage problems, ensuring normal use in winter and summer.
– Interface type: Standardized metric sealed conical interface, one-piece ferrule locking, no need for additional sealing, tight fit, and easy assembly and disassembly.
– Protection rating: Equivalent to IP67 dustproof and leakproof, isolating dust, rainwater, and oil stains to ensure cleanliness of the oil circuit.
– Installation method: Compression fitting connection, hole positions are consistent with the original, no need to modify the circuit or drill holes, can be quickly installed by one person, and must be tightened to the specified torque.
– Applicable Scenarios: Compatible with SANY equipment hydraulic systems for media diversion and merging; suitable for complex working conditions such as mining and infrastructure construction; can be used for pipeline modification, fault replacement, and pre-installation on new machines.
– Maintenance cycle: It is recommended to check the interface every 1500 hours, and replace it in time if there is leakage or deformation; under severe operating conditions, the interval should be shortened to 800 hours, and the interface should be properly sealed during maintenance.
