DIN EN 857 1SC is a compact hydraulic hose with one steel-wire braid reinforcement, designed for hydraulic systems where a smaller outside diameter or tighter routing is useful. To select it, match the hose’s nominal bore, working pressure, temperature range, fluid compatibility, bend radius, and end connections to the actual system requirements. The designation alone does not confirm that a hose is suitable for every pressure, fluid, or installation. At Hengshui Xinchi Hose Manufacturing Co., Ltd., we recommend checking the product specification and assembly requirements before placing a bulk order.
This guide is for hydraulic equipment manufacturers, maintenance teams, distributors, and purchasing professionals comparing compact wire-braided hoses. It is intended to help buyers prepare a technically useful specification and avoid selecting by size or price alone. If you are replacing an existing hose, use its markings and equipment documentation as starting points, then confirm that the replacement matches the application. A visually similar hose may have a different pressure rating, bend radius, or fitting compatibility.
DIN EN 857 1SC is a specification for a compact hydraulic hose construction. The “1SC” designation refers to a hose with one high-tensile steel-wire braid reinforcement, positioned between an inner tube and an outer cover. The inner tube is generally made from synthetic rubber selected for compatibility with hydraulic fluids, while the cover is designed to protect the reinforcement and tube from external exposure.
The compact construction can help with routing in equipment where space is limited. However, “compact” does not mean that every installation can use a tighter bend or a smaller hose size without consequence. Bending below the manufacturer’s specified minimum radius, twisting the hose, or operating above its pressure rating can shorten service life or create a safety risk.
EN 857 1SC product lines commonly include nominal bores from DN6 to DN25, but the exact size range depends on the manufacturer. Working pressure is size-dependent: a hose with a larger bore may have a different rated pressure from a smaller-bore hose in the same product family. Buyers should use the pressure value for the exact size and construction rather than applying one rating to the full range.
Temperature performance also depends on the hose construction, fluid, and service conditions. Some product specifications list a working temperature range around -40°C to +100°C for compatible hydraulic fluids, but this should not be assumed for every hose or medium. Confirm the supplier’s stated limits, especially for water-based fluids, elevated temperatures, or applications involving air or gas.
| Specification | What to Confirm | Why It Matters |
|---|---|---|
| Nominal bore | Hose size and required internal diameter | Affects flow capacity and pressure loss. |
| Working pressure | Rated pressure for the exact size and assembly | Must suit the system’s maximum operating pressure and pressure variation. |
| Temperature | Continuous and, where relevant, intermittent limits | Heat can affect hose materials and fluid performance. |
| Minimum bend radius | Value for the selected size | Prevents routing that places excessive stress on the hose. |
| Fluid compatibility | Hose suitability for the specified medium | Incompatible fluids can damage the tube or affect assembly performance. |
| Fittings and assembly | End type, thread, material, and crimp requirements | Correct hose selection does not guarantee a compatible finished assembly. |
EN 857 1SC may be considered for hydraulic machinery, mobile equipment, and industrial systems where a single-wire-braid hose meets the design requirements. Its compact profile can be useful where routing space is restricted, provided the installation respects the specified bend radius and does not expose the hose to conditions outside its ratings. The application should determine the selection, not the hose designation by itself.
Start with the system’s maximum working pressure, including relevant operating peaks, and compare it with the rating for the selected hose size and assembled configuration. Identify the hydraulic fluid and its temperature range, then confirm compatibility with the hose materials. Finally, check routing, movement, abrasion exposure, and the connection type at both ends.
Record the normal and maximum operating pressure, fluid type, operating temperature, and expected duty cycle. Note whether the hose is stationary or moves during machine operation. If the system has pressure fluctuations or frequent movement, include those conditions in the supplier discussion rather than quoting only a nominal pressure.

Use the equipment design or flow requirement to determine the nominal bore. Then verify the working pressure of the exact bore in the current product datasheet. Avoid substituting a smaller bore simply to reduce outside dimensions, because the change can affect flow and pressure loss.
Measure the installation space and compare it with the hose’s outside diameter and minimum bend radius. Make sure the hose is not stretched, sharply bent, twisted, or positioned where it can rub against moving or hot components. Specify fitting style, thread standard, orientation, and assembly length so the finished hose can connect correctly.
Before purchase, align on product markings, packaging, inspection documents, and any applicable customer requirements. Provide the requested quantity, length, size mix, fitting details, and destination when asking for a quotation. If a project requires a particular standard or test documentation, state that requirement explicitly and confirm availability before order confirmation.
Pricing for EN 857 1SC hose can vary with size, order quantity, requested length, packaging, fittings, and documentation. A hose-only order and a finished hose assembly are different purchasing scopes, so compare quotations on the same basis. Minimum order quantities and lead times can also vary according to product availability, customization, and shipping arrangements.
For a more accurate quotation from Hengshui Xinchi Hose Manufacturing Co., Ltd., send the hose size, required pressure rating, quantity, length, application conditions, and whether fittings are required. If you are replacing an existing product, provide its markings or a clear specification rather than relying only on a photograph. We can review the request and clarify which product details need confirmation before order placement.
One common mistake is treating the EN 857 1SC designation as a complete guarantee of suitability. It identifies the hose type, but buyers still need the size-specific pressure and bend-radius data. Another mistake is overlooking fluid compatibility or assuming that a temperature limit applies equally to every medium and operating condition.
Buyers should also avoid choosing a hose solely because it fits the available space. Incorrect bore sizing can affect system performance, while unsuitable routing can place extra mechanical stress on the hose. Finally, confirm that the hose and fittings are compatible as an assembly, and follow the applicable assembly instructions rather than mixing components based only on apparent fit.
DIN EN 857 1SC is a single-steel-wire-braid compact hydraulic hose construction that may suit systems needing a space-conscious routing option. The right selection depends on the exact bore, size-specific working pressure, temperature, fluid compatibility, bend radius, and end connections. Use the current product data for the precise hose you intend to buy, and do not infer ratings from the designation alone.
Your next step is to prepare a complete inquiry with the application conditions, size, quantity, length, and fitting details. Hengshui Xinchi Hose Manufacturing Co., Ltd. can review these requirements and discuss suitable hose supply options for your project.
