Hydraulic Hose Assembly

The JIDONGDA Hydraulic Hose Assembly is specifically designed for high-pressure oil conveyance across various hydraulic systems. Manufactured using precision crimping technology and compatible with a wide range of end fittings, it effectively addresses common industry issues such as leakage, insufficient pressure resistance, connection unreliability, and short service life. As a professional manufacturer of fluid transfer equipment, the brand maintains strict quality control at every stage of production, ensuring structural stability, exceptional durability, and a high safety margin; this makes the product suitable for long-term use under intense, continuous industrial loads.

Key Product Features

1. Superior pressure resistance and structural stability

The hose features a three-layer construction: an oil-resistant synthetic rubber inner tube, a high-strength steel wire reinforcement layer (braided or spiral-wound), and an abrasion-resistant synthetic rubber outer cover. Designed for a maximum working pressure of 6,000 PSI (with customizable pressure ratings), the product withstands burst tests at four times the rated working pressure. It maintains seal integrity without deformation or structural damage during prolonged high-pressure operation, meeting the demands of heavy-duty hydraulic systems.

2. Versatile fittings and broad compatibility

The product supports international connection standards—including BSP, NPT, JIC, ORFS, SAE flanges, and quick-connect couplings—and is compatible with both carbon steel and stainless steel fittings. Precision crimping technology ensures a tight fit, eliminating issues such as loosening, slippage, or oil leakage, while significantly enhancing connection reliability.

3. Flexibility, durability, and suitability for harsh environments

An optimized design ensures excellent flexibility, allowing for easy installation in confined equipment spaces without compromising high-pressure performance. The operating temperature range is -40°C to +100°C. The outer rubber layer is resistant to abrasion and corrosion, guaranteeing stable operation in challenging conditions characterized by temperature fluctuations and intense friction.

4. Extended service life and reduced operating and maintenance costs

The Hydraulic Hose Assembly has undergone over 200,000 pulse fatigue test cycles, demonstrating excellent resistance to fatigue loads and aging. It withstands prolonged pressure fluctuations and equipment vibration, effectively reducing failure rates and long-term maintenance costs.

Professional Performance Testing

1. High-Pressure Resistance Test

During tests simulating extreme conditions—specifically, pressure four times the rated operating level—the product was subjected to sustained high pressure. No leaks, fitting disconnections, or hose deformations were observed, confirming the structural integrity and a substantial safety margin.

2. Impulse Fatigue Test

After 200,000 continuous impulse cycles, the product maintained stable performance characteristics and high fatigue resistance. It is capable of withstanding the frequent pressure spikes typical of long-term hydraulic system operation, thereby slowing the aging process and preventing premature failure.

3. Fitting Attachment Strength Test (Pull-out Resistance)

Professional testing confirmed the reliability of the crimp and the high strength of the connection. The product effectively withstands tensile and torsional loads during equipment operation, eliminating the risk of fitting disconnection.

Practical Application Example

Example 1: Application in construction machinery (excavator)

A domestic manufacturer of construction machinery faced frequent hose leaks and ruptures in excavator boom hydraulic systems, resulting in downtime and high repair costs. After switching to specialized JIDONGDA high-pressure hoses, the system successfully withstood the high-frequency flexing and pressure spikes associated with the manipulator's operation. After 12 months of continuous field use, the hoses showed no leaks or deformation, performing excellently during all-weather outdoor construction operations. The hydraulic system failure rate dropped by 80%, hose service life more than tripled, and construction efficiency increased significantly.
