Tube & Cover Materials

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.

Pressure Range Customization

Pressure Range Options

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.

Measuring tape

Cut Length & Hose Assembly

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.

Wire Reinforcement

Reinforcement Structure

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.

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.
