252100920 hose for XCMG ZL50G/ZL50GL Wheel Loader

product parameters

Product Name: Hose Assembly
Part No.: 252100920
Applicable Model: XCMG ZL50G, ZL50GL Wheel Loader
Type: Hydraulic / air flexible connection hose
Structure: Inner rubber layer, reinforcement layer, outer rubber layer, metal fittings on both ends
Fitting Type: OEM standard interface (subject to actual product)
Function: Transfer of hydraulic oil, compressed air, and other media; pipeline vibration damping
Working Condition: Quarry mining, aggregate yard, heavy earthwork and construction projects

Applicable Scenarios

Used in hydraulic and air pipeline positions requiring flexible connection on XCMG ZL50G and ZL50GL wheel loaders, including working hydraulic circuits, steering circuits, and brake air circuits where relative movement or vibration transmission exists. Widely used in quarry, aggregate yard, and earthwork construction sites with heavy loads, dust, and mud splash. It is a key connection component for ensuring pipeline system sealing and vibration damping.

▪ OEM interface dimensions and length for direct replacement on ZL50G/ZL50GL
▪ Inner layer resists hydraulic oil corrosion; reinforcement layer provides reliable pressure capacity for loader hydraulic systems
▪ Outer layer resists wear and aging for dusty and muddy mine/aggregate site conditions
▪ Flexible connection absorbs installation deviation and equipment vibration, reducing stress on rigid fittings
▪ Factory crimping quality inspection reduces fitting leakage risk
▪ Can be stocked together with various hydraulic hoses, air pipes, and fitting accessories for the same model

FAQ 

Q：When does a hose assembly need replacement?
A: Replace when the outer layer shows cracking, bulging, or severe wear exposing the reinforcement layer, or when oil/air seepage appears at fittings. Aged hoses have reduced pressure capacity and burst risk.

Q：Is fitting leakage always caused by the hose?
A: Not necessarily. Check the fitting sealing surface for damage, O-ring aging, and thread looseness first. After confirming the fitting is intact, inspect the hose crimp area for leakage.

Q：What to note during hose installation?
A: Avoid excessive bending or twisting; bending radius should not be too small. Do not force the hose into position, which may damage the crimp area. Ensure clearance from surrounding components to prevent friction wear.

Q：Can 252100920 be used on other loader models?
A: Cross-model use is not recommended. The length and fitting type are designed for ZL50G/ZL50GL pipeline layout. Installation positions and interfaces may differ on other models. Confirm compatibility by part number.

Q：How to maintain the hose assembly daily?
A: Periodically inspect the outer layer for wear, cracks, and bulging, and fittings for seepage traces. During hydraulic system maintenance, check hose condition and replace promptly when aging signs appear.
