252904791 air pipe for XCMG ZL50G/ZL50GL Wheel Loader

product parameters

Product Name: Air Pipe
Part No.: 252904791
Applicable Model: XCMG ZL50G, ZL50GL Wheel Loader
Type: Air circuit flexible transfer 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: Compressed air transfer, air circuit vibration damping
Working Condition: Quarry mining, aggregate yard, heavy earthwork and construction projects

Applicable Scenarios

Used in air circuit positions requiring flexible connection on XCMG ZL50G and ZL50GL wheel loaders, including brake air circuits, auxiliary air circuits, and sections with relative movement or vibration transmission. 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 air circuit system sealing and vibration damping.

▪ OEM interface dimensions and length for direct replacement on ZL50G/ZL50GL
▪ Inner layer resists compressed air and minor oil mist; reinforcement layer provides reliable pressure capacity
▪ 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 air pipes, hoses, and fitting accessories for the same model

FAQ 

Q：When does an air pipe need replacement?
A: Replace when the outer layer shows cracking, bulging, or severe wear exposing the reinforcement layer, or when air leakage appears at fittings. Aged pipes have reduced pressure capacity and burst risk.

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

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

Q：Can 252904791 be used on other loader models?
A: Cross-model use is not recommended. The length and fitting type are designed for ZL50G/ZL50GL air circuit layout. Installation positions and interfaces may differ on other models. Confirm compatibility by part number.

Q：How to maintain the air pipe daily?
A: Periodically inspect the outer layer for wear, cracks, and bulging, and fittings for air leakage traces. During air circuit maintenance, check pipe condition and replace promptly when aging signs appear.
