• Multi-layer steel wire reinforcement, high burst resistance, withstand frequent hydraulic pressure impact.
• Oil and ozone resistant rubber material, slow aging, suitable for harsh engine compartment environment.
• Precision crimped steel connectors, high pulling resistance, reduce the risk of joint leakage.
• OEM hose length and bending shape, easy installation without forced stretching or twisting.
• Good low-temperature flexibility, will not harden and crack under cold winter conditions.
• Smooth inner wall reduces fluid resistance, stable oil flow for consistent hydraulic response.
• Wear-resistant outer rubber cover, protect inner steel wire layer from sand and mud scratch.
• Batch impulse fatigue and pressure inspection before delivery to reduce on-site failure risk.

FAQ 

Q：Which loader does 251400232 hose fit?
A：It is custom made for XCMG ZL50G and ZL50GL wheel loaders. Confirm machine serial number before purchase to avoid wrong part selection. This hydraulic hose assembly is used for hydraulic oil transmission and cannot be directly applied to other series equipment.

Q：What signs mean the hose assembly needs replacement?
A：Outer rubber cracking, blistering, delamination, oil weeping or spraying, connector leakage, hose bulging under pressure.

Q：What should be noted during hose installation?
A：Check thread and hose appearance before installation; avoid twisting the hose; reserve enough slack to absorb vibration; tighten the connector with proper torque.

Q：What are common causes of hose damage?
A：Repeated pressure impact; rubber aging and ozone erosion; excessive bending beyond minimum radius; sharp edges cutting outer rubber; incorrect installation twisting.

Q：Can damaged hydraulic hose be repaired and reused?
A：Hose damage cannot be reliably repaired. Temporary wrapping or glue repair will fail quickly under hydraulic pressure and vibration. Replace new hose assembly directly.

Q：How to inspect hose during daily maintenance?
A：Check hose surface rubber cracks, blisters and oil leakage before heavy-load operation. Focus inspection on bending area and connector joints.

Q：What failures will a failed hose cause?
A：Damaged hose leads to hydraulic oil leakage, insufficient working pressure. Severe rupture will cause sudden loss of hydraulic power and bring operation risks.
