381200421 XCMG GR2605 motor grader connecting pipe

381200421 is the original hydraulic connection pipe for the XCMG GR2605 grader. It’s used for rigid oil circuit connections between valve groups, oil pumps, cylinders, and other components. It’s pressure-resistant, has excellent sealing, and provides stable piping.

Core Functions and Roles

As a rigid oil circuit channel in the hydraulic system, it enables oil communication between hydraulic components, ensuring smooth oil flow and stable pressure.

The rigid structure provides accurate positioning and is not easily deformed. It maintains the pipe position under vibration conditions, protecting the joints from loosening.

It works with seals to form a reliable seal, preventing oil leakage and air intake, ensuring the power output of the hydraulic system.

It’s suitable for short-distance connections between valve blocks, solenoid valves, and hydraulic circuit integration blocks, simplifying piping layout.

Key Technical Parameters

Model: 381200421
Name: Connecting Pipe
Compatible Model: XCMG GR2605 Grader
Material: High-precision seamless steel pipe, rust-proof surface treatment
Features: Original factory dimensions, high concentricity, smooth sealing surface, pressure-resistant and vibration-resistant

Replacement and Maintenance Points

Clean the pipe body and sealing surfaces at both ends before installation to prevent impurities from entering the oil circuit.

Align the pipe with the center during assembly; do not force it to be installed at an angle to prevent damage to the sealing surface.

It is recommended to replace O-rings and other seals simultaneously during disassembly and assembly to ensure a good seal.
