Product Advantages
Superior Pressure Resistance:
Reinforced steel wire layers prevent burst under peak hydraulic loads.
Abrasion & Corrosion Resistant:
Outer rubber layer resists oil, UV rays, and mechanical wear.
Flexible Installation:
Maintains flexibility at low temperatures for easy routing in tight excavator compartments.
Cost-Effective:
Extended service life reduces maintenance frequency and replacement costs.
Craftsmanship & Technology
We adopt a high-temperature vulcanization process to bond inner rubber, reinforcement layers, and outer rubber tightly, eliminating delamination risks. Precision extrusion technology ensures uniform inner diameter, optimizing hydraulic fluid flow and minimizing pressure loss. Each hose undergoes strict pressure testing and quality inspection before leaving the factory, complying with ISO 9001 and SAE J517 standards.
Application
FieldsIdeal for hydraulic systems of mini, medium, and large excavators, applicable in construction sites, mining operations, quarrying, forestry, and infrastructure projects. Compatible with leading excavator brands like Caterpillar, Komatsu, and Hitachi.
Services
