FAQ

Q1:What is the typical working pressure range for medium-pressure hydraulic braided hose?

A1:

Medium-pressure hydraulic braided hoses are designed for working pressures between 377–3,045 PSI (approximately 26–210 bar), depending on the hose diameter (e.g., 3/16" at 3,045 PSI/210 bar, 1/2" at 2,030 PSI/140 bar, up to 2" at 377 PSI/26 bar). They meet SAE 100R1AT standards and are ideal for medium-duty applications such as mobile equipment, machine tools, and agricultural systems using petroleum or water-based hydraulic fluids.

Q2:What is the construction of this braided hose, and how does it compare to higher-pressure options?

A2:

This hose features an oil-resistant synthetic rubber inner tube, one high-tensile steel wire braid reinforcement, and an oil-, abrasion-, and weather-resistant synthetic rubber cover. Compared to spiral hoses (which handle higher pressures but are heavier and less flexible), this single-braid design is lighter, more flexible, and offers a tighter minimum bend radius (e.g., 178 mm for 1/2", 241 mm for 3/4"), making it suitable for confined spaces in medium-pressure systems up to 3,045 PSI.

Q3:What should I pay attention to during installation to prevent premature failure?

A3:

To maximize service life:

Never exceed the minimum bend radius (e.g., 178 mm for 1/2" hose, 305 mm for 1").
Avoid twisting, kinking, or excessive tension during installation.
Keep the hose away from sharp edges, heat sources, and abrasive surfaces.
Use proper crimped fittings and secure the hose with clamps to reduce vibration and abrasion. Most early failures are caused by tight bends, external wear, or pressure spikes—regular visual inspections help catch issues early. Operate within the -40°C to +121°C temperature range for optimal performance.

Q4:How do I select the correct size and specification for my hydraulic system?

A4:

Follow the STAMPED method:

Size (inner diameter based on required flow rate, e.g., 1/2" ID: 12.3–13.5 mm).
Temperature (operating range: –40°C to +121°C).
Application (fluid type like petroleum or water-based, motion, environment such as mobile or agricultural).
Material (compatibility with hydraulic fluids; oil-resistant synthetic rubber).
Pressure (choose hose with at least 4:1 burst pressure safety factor, e.g., 1/2" WP: 2,030 PSI, BP: 560 bar).
Ends (fitting type and connection).
Delivery (length and routing). Always refer to the manufacturer’s technical parameters table and select a hose that meets SAE 100R1AT standards for your application.
