XCMG XE2000 Excavator Dedicated Hoses Assembly: Part No. 803419827

In the hydraulic and fuel transmission systems of the XCMG XE2000 excavator, the hose assembly is the “flexible core hub” connecting the fixed pipelines and moving parts (such as hydraulic cylinders, slewing platforms, and fuel pumps). Its fitting accuracy, pressure resistance, and sealing reliability directly determine the fluid transmission efficiency. Once the hose assembly has dimensional deviations or insufficient pressure resistance, it is very easy to cause high-pressure fluid leakage and pipe rupture, which in turn leads to equipment downtime and project delays. Our 803419827 hose assembly is an original equipment manufacturer (OEM) part 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 ≤ ±2.5mm, inner diameter tolerance precisely controlled within ±0.18mm, connector thread accuracy reaching 5g/6g level, and crimping depth deviation between connector and hose ≤ ±0.08mm. It perfectly matches the connection requirements of the XE2000 hydraulic valve group, cylinder ports, and fuel tank, allowing for direct assembly without additional cutting or grinding. 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 vibration and high-pressure operating conditions.

The scientific design of materials and structure gives this hose assembly excellent durability and adaptability to complex environments. The main body of the hose adopts a three-layer composite reinforced structure: the inner layer is made of high-purity oil-resistant nitrile rubber (purity above 98.5%), which can withstand the corrosion of various fluids such as hydraulic oil, diesel, and lubricating oil. It does not swell or crack after long-term contact, and the inner wall smoothness reaches Ra0.4μm, which greatly reduces fluid transmission resistance and avoids the accumulation of impurities; the middle layer is a high-density polyester fiber braided mesh with a braiding density of up to 96% and a tensile strength of 20MPa, which can easily withstand the maximum working pressure of 31.5MPa of the XE2000 hydraulic system and effectively prevent the hose from bursting under high pressure; the outer layer is made of wear-resistant neoprene rubber with a Shore hardness of 68±3A, which can resist the impact of gravel and dust friction in mining and infrastructure construction, and has an ultra-wide temperature adaptability range of -45℃ to 125℃. It does not crack in low-temperature environments and does not soften or deform under high-temperature conditions. The connectors at both ends are made of 304 stainless steel, cold-forged into a single piece, and undergo double-layer galvanizing and passivation treatment. They achieve a rust-proof rating of no corrosion after 72 hours of salt spray testing. The connectors are formed in one piece with the hose using a CNC crimping machine, achieving a sealing pressure at the crimp point that is 1.6 times the system’s maximum pressure, completely eliminating the risk of leakage. Compared to ordinary single-layer rubber hoses, their service life is extended by more than 6 times, significantly reducing hydraulic system failures caused by hose damage, and lowering equipment maintenance costs and downtime losses.

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 803419827 hose assembly is a cost-effective choice.
