803192071 XCMG GR2605 motor grader O-ring

803192071 XCMG GR2605 motor grader O-ring

The 803192071 O-ring is an original equipment manufacturer (OEM) seal for the XCMG GR2605 grader. It is compatible with various interface sealing requirements of the machine’s hydraulic system, undertaking static and dynamic sealing tasks in critical components such as cylinders, valve assemblies, and pipe joints, directly affecting the pressure stability and operating efficiency of the hydraulic system. In harsh operating environments such as highway construction, mine stripping, airport runway construction, and large-scale earthwork projects, involving long-term heavy loads, high-frequency vibration, dust and mud erosion, and alternating high and low temperatures, it can stably withstand working pressures up to 60MPa, and is not prone to deformation, aging, or leakage, effectively reducing the risk of hydraulic system seal failure and ensuring continuous equipment operation.

The O-rings are precision molded from imported fluororubber (FKM) raw materials, with a Shore hardness of 75HA, tensile strength ≥15MPa, elongation at break ≥300%, and excellent elastic recovery performance. They exhibit outstanding oil resistance, compatible with XCMG original L-HM 46/68 anti-wear hydraulic oil, high-temperature hydraulic oil, and various hydraulic media, with an oil swelling rate ≤5% (100℃×72h). intrusion. They are suitable for various static and low-frequency dynamic sealing scenarios in hydraulic systems, perfectly matching the original vehicle interface size, and can directly replace aged or damaged original vehicle O-rings.
