XCMG XE2000 Excavator Dedicated Hoses Assembly: Part No. 803419829

In the hydraulic and fuel transmission systems of the XCMG XE2000 excavator, hose assemblies serve as “flexible transmission links” connecting fixed pipelines with moving components (such as hydraulic cylinders and slewing mechanisms). Their flexibility, adaptability, pressure resistance, and sealing performance directly determine the safety and stability of fluid transmission. If the hose assembly has dimensional deviations or insufficient pressure resistance, it can easily lead to high-pressure fluid leakage, pipe rupture, or even equipment shutdown. Our 803419829 hose assembly is a genuine XCMG-grade accessory specifically designed for the XE2000 model. Manufactured in strict accordance with XCMG’s original fluid piping technical standards and assembly drawings, it undergoes four precision tests, from hose length and inner diameter specifications to the dimensions of the connectors at both ends: hose length error ≤ ±3mm, inner diameter tolerance controlled within ±0.2mm, connector thread precision reaching 5g/6g level, and crimping depth deviation between connector and hose ≤ ±0.1mm. It perfectly matches the connection requirements of the XE2000 hydraulic valve group, cylinder interface, and fuel tank, allowing for direct assembly without additional cutting or adjustment. This completely eliminates potential problems such as connection jams and fluid leakage caused by size mismatches, ensuring stable transmission of the piping system under high-frequency movement and high-pressure conditions.

Scientific upgrades to materials and structure give this hose assembly exceptional durability and environmental adaptability. The main body of the hose adopts a three-layer composite structure: the inner layer is made of oil-resistant nitrile rubber with a purity of over 98%, which can withstand corrosion from various fluids such as hydraulic oil and diesel, without swelling or cracking after long-term contact, and the inner wall is smooth and burr-free, reducing fluid transmission resistance; the middle layer is a high-strength polyester fiber braided mesh with a braiding density of over 95% and a tensile strength of 18MPa, which can withstand the maximum working pressure (31.5MPa) of the XE2000 hydraulic system, preventing the hose from bursting under high pressure; the outer layer is made of wear-resistant neoprene rubber with a Shore hardness of 65±5A, which can withstand the impact of gravel and dust friction in mining and infrastructure construction, and has a wide temperature adaptability from -40℃ to 120℃, without becoming brittle at low temperatures or softening at high temperatures. The connectors at both ends are cold-forged from 304 stainless steel and galvanized and passivated, achieving a rust-proof rating that shows no rust after 48 hours of salt spray testing. They are formed in one piece with the hose using specialized crimping equipment, with the crimped joints achieving a sealing pressure 1.5 times the system’s maximum pressure, eliminating any risk of leakage. Compared to ordinary single-layer rubber hoses, their service life is extended by more than 5 times, significantly reducing hydraulic system failures caused by hose damage and lowering equipment maintenance costs.

Whether you’re a maintenance technician on an engineering team needing to replace aging or damaged hose assemblies during pipeline maintenance, or a parts distributor looking to stock highly compatible and reliable fluid transfer spare parts for your customers, the 803419829 hose assembly is a cost-effective choice.
