This is a high-pressure hose assembly specifically designed for the hydraulic system of Volvo excavators, carrying fluid under significant pressure. Manufactured to meet stringent durability and pressure resistance standards, it provides reliable fluid transfer, unlike a worn hose that can lead to leaks and system inefficiency. Operators may observe a loss of hydraulic power, erratic implement movement, or visible fluid leaks when this hose begins to fail.
Always verify with serial number before ordering.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The initial indication of a failing hose is often a slow hydraulic fluid leak, which may appear as dampness or small puddles. If ignored, the leak will likely worsen, leading to a noticeable decrease in hydraulic system pressure and slower, less responsive machine functions. A significant hose rupture can result in a sudden loss of hydraulic power and potential contamination of the hydraulic system.
Ensure that the threads on both the hose fittings and the machine's ports are clean and undamaged prior to connection to prevent leaks and ensure a secure seal. Avoid twisting the hose during tightening, as this can compromise its internal structure.
Inspect all other hydraulic hoses, fittings, and the hydraulic fluid condition and level.
