The inner tube is made from oil-resistant synthetic rubber (NBR), suitable for mineral-based hydraulic oils and stable operation under continuous pressure.
The outer cover uses weather- and abrasion-resistant synthetic rubber (CR) to protect the hose against ozone, UV exposure, and mechanical wear in industrial environments.
Working pressure capability varies depending on hose construction, reinforcement type, and applicable standards.
Standard braided designs are used for medium-pressure systems, while spiral-reinforced constructions are selected for high-pressure and high-impulse hydraulic applications.
Hoses are supplied in continuous coils or cut to length according to customer specifications and system layouts.
Professional hose assembly services, including cutting and crimping, are available to ensure dimensional accuracy and consistent assembly quality.
Braided reinforcement structures, such as single-wire and double-wire designs, provide a balance of flexibility and pressure resistance.
Spiral-reinforced constructions are used for applications requiring higher pressure capacity and extended impulse life.
3/8 hydraulic hose rated at 3000 PSI is commonly used in agricultural machinery, tractors, and light industrial equipment.
It provides reliable pressure handling for hydraulic circuits with moderate flow requirements while maintaining flexibility and abrasion resistance.
For construction equipment and mobile hydraulic systems, the 3/8 hydraulic hose with a 4000 PSI working pressure offers enhanced strength and safety margin.
This option is widely used in excavators, loaders, and material handling machinery.
High-pressure 3/8 hydraulic hose rated up to 5000 PSI is designed for demanding hydraulic environments where pressure spikes and continuous operation are expected.
It is suitable for heavy-duty industrial systems and specialized hydraulic applications.
To ensure compatibility with different hydraulic systems, Kingdaflex offers a wide range of fitting options for 3/8 hydraulic hose assemblies.
All fittings are precisely machined to provide leak-free connections and long-term performance.

Yes, 3/8 hydraulic hose is available by the foot or in bulk coils for flexible cutting and assembly.
The minimum order quantity for our 3/8 inch Hydraulic Hose is 200 meters.
Common options include JIC, NPT, and female end fittings designed for standard 3/8 inch hydraulic hose dimensions.
The working pressure of the hose should always be equal to or higher than the maximum system pressure, including pressure spikes. In most applications, a safety factor is applied according to industry standards. Our technical team can help evaluate your system pressure, duty cycle, and operating conditions to recommend the appropriate hose construction.
Each hydraulic hose is manufactured under controlled processes and tested according to applicable standards. Typical tests include dimensional inspection, pressure testing, leakage checks, and visual inspection to ensure consistent performance and safety before delivery.
To produce a correct hose assembly, we typically need the hose size, working pressure, hose length, fitting types, fitting orientation, and application details. Providing accurate information ensures the assembly performs reliably in your hydraulic system.
