 Letone Super Hercules hydraulic hose is a high-performance hose designed for construction machinery (such as excavators and loaders), with the following core advantages:

 

1. Super high pressure resistance and impact resistance

Working pressure: up to 42MPa (some models are higher), far exceeding ordinary hoses (usually 2535MPa).
Reinforcement layer structure: 4~6 layers of high-strength steel wire braiding/winding, higher bursting pressure resistance, avoiding pipe bursting during high-pressure operation.
 

2. Excellent oil and high temperature resistance

Inner rubber layer: oil-resistant NBR (nitrile rubber) or FKM (fluoro rubber) is used to resist hydraulic oil corrosion and extend service life.
Temperature range: 40°C ~ +120°C, suitable for high temperature working environment of excavators.

3. Wear-resistant, anti-bending, suitable for harsh working conditions

Outer rubber: high wear-resistant synthetic rubber is used to resist rock and mud friction and reduce external damage.
Good flexibility: optimize the bending radius to avoid frequent arm movements causing hose fracture.
 

4. Professional customization, easy installation

Standard crimping process: ensure that the joint and hose are tightly combined to prevent oil leakage.
Multiple specifications available: match different brands of excavators (such as Carter, Komatsu, Sany, Xugong, etc.).
 

5. High cost performance, reducing maintenance costs

Long service life: 2~3 times more durable than ordinary hoses, reducing replacement frequency.
Reduce downtime losses: avoid maintenance delays due to hose bursts.
 
Summary: Why choose Litong Super Hercules?
✅ High pressure and impact resistance - reduce the risk of pipe bursting
✅ Oil and high temperature resistance - adapt to the harsh working conditions of excavators
✅ Wear and bending resistance - extend service life
✅ Professional customization - perfectly match the original specifications
✅ High cost performance - reduce long-term maintenance costs
 
If it is an excavator that works frequently, replacing ordinary hoses may soon leak oil again, and Litong Super Hercules hydraulic hose can provide a longer-term and more stable solution, which is an ideal choice for construction machinery hydraulic systems.
 
Recommendation: Choose a regular channel when purchasing, ensure genuine products, and have professionals install them to ensure optimal performance.
