803173449 connector XCMG XE2000 excavator spare parts

XCMG XE2000 Excavator Dedicated Connector: Part No. 803173449

In the hydraulic and fuel transmission systems of the XCMG XE2000 excavator, the connectors are the “critical connecting hubs” that enable precise connections between pipes of different specifications and core components (such as hydraulic valve groups, cylinders, and fuel pumps). Their connection accuracy and sealing reliability directly determine the safety and efficiency of fluid transmission. If the connector dimensions are off or the seal fails, it can easily lead to high-pressure fluid leakage and a sudden drop in system pressure, not only wasting oil but also potentially causing equipment downtime for maintenance and delaying project progress.

Our 803173449 connector is a genuine XCMG-grade accessory specifically designed for the XE2000 model. Manufactured in strict accordance with XCMG’s original fluid connection technical standards and drawing parameters, it undergoes four precision tests, from thread specifications, interface diameter, sealing surface accuracy to installation positioning dimensions—thread accuracy reaches 5g/6g level, interface diameter error ≤ ±0.02mm, sealing surface roughness Ra≤0.6μm, and installation positioning hole alignment deviation ≤0.03mm. It perfectly matches the connection requirements of the XE2000 hydraulic and fuel lines, allowing for direct assembly without additional grinding, cutting, or adjustment. This completely eliminates potential problems such as loose connections, fluid leakage, and installation jamming caused by size mismatches, ensuring stable transmission of the pipeline system under high-pressure, high-frequency vibration conditions.

Scientific upgrades in materials and processes have endowed this connector with exceptional pressure resistance, corrosion resistance, and durability. The connector body is made of high-quality 45# carbon steel, cold-forged into a single piece, and subsequently tempered (hardness reaching HRC28-32) and surface galvanized passivation. This results in a tensile strength exceeding 600MPa, easily withstanding the maximum working pressure of 31.5MPa in the XE2000 hydraulic system. Long-term use is less prone to issues such as thread stripping, interface deformation, and structural cracking. The galvanized layer is over 12μm thick, forming a dense protective layer that effectively resists immersion in mud and water, dust erosion, and chemical corrosion from hydraulic oil and diesel fuel during mining and construction, preventing the connector from experiencing reduced sealing performance or structural strength damage due to rust. Meanwhile, the copper sealing gasket built into the joint has excellent elastic deformation ability and oil resistance. After installation, it can tightly fill the sealing gap and maintain a stable sealing effect even in a wide temperature range of -30℃ to 150℃. Compared with ordinary rubber seals, its high pressure resistance and anti-aging performance are improved by more than 3 times, making it suitable for the complex and ever-changing working environment of excavators.

Whether you’re a maintenance technician on an engineering team needing to replace worn, leaking, or corroded connectors during pipeline maintenance, or a parts distributor looking to stock highly compatible and reliable fluid connection spare parts for your customers, the 803173449 connector is a cost-effective choice.
