803402037 XCMG GR2605 motor grader connector

803402037 is an original hydraulic connector for the XCMG GR2605 grader. It is used for connecting hydraulic lines, valve blocks, filter elements, oil circuits, cylinders, etc., providing pressure resistance, sealing, shock resistance, and anti-loosening properties, ensuring stable and reliable oil circuit connections.

Core Functions and Roles

Used for connecting and transferring hydraulic system oil circuits, ensuring smooth flow of high-pressure hydraulic oil and providing stable power transmission to the entire machine’s working devices.

Employing a precision sealing structure, it prevents oil leakage under high pressure, vibration, and long-term operation, maintaining stable system pressure.

Original standard threads and installation dimensions ensure a high degree of matching, a close fit, and resistance to loosening and stripping over long-term use.

High-strength material, oil-resistant, corrosion-resistant, and impact-resistant, suitable for harsh environments such as construction sites with dust, mud, and bumps.
