DIN EN 857 2SC Hydraulic Hoses: Specifications, Applications, and Selection Guide
DIN EN 857 2SC is a compact hydraulic hose specification for applications that need a smaller bend radius than many conventional wire-braid hoses. The “2SC” construction uses two braided steel-wire reinforcement layers, with an oil-resistant inner tube and a protective outer cover. Typical service-temperature guidance is approximately -40°C to +100°C for compatible hydraulic fluids, while water-based fluids commonly have a lower maximum of about +70°C; always confirm the exact hose and fluid ratings before purchase. At XINCHI, we recommend selecting by the complete system requirements—not by the standard designation alone.

Key Takeaways
- DIN EN 857 2SC is a compact, two-wire-braid hydraulic hose intended for pressure lines where routing space or bend radius matters.
- Pressure capacity, minimum bend radius, and dimensions vary by nominal bore and manufacturer; use the product’s technical data for the selected size.
- Check fluid compatibility, operating temperature, pressure peaks, fittings, and installation conditions before approving a hose.
- Share your technical requirements with XINCHI to evaluate suitable hose and assembly options for your application.
Who This Guide Is For
This guide is for hydraulic equipment manufacturers, distributors, maintenance teams, and procurement professionals comparing compact hose options. It is also useful when replacing an existing hose and checking whether a 2SC construction can meet the machine’s operating conditions. The information supports product evaluation, but it does not replace the equipment manufacturer’s requirements or a hose supplier’s size-specific data. If the application is safety-critical, verify the complete assembly with the responsible engineer.
What Is a DIN EN 857 2SC Hydraulic Hose?
DIN EN 857 2SC describes a compact hydraulic hose construction covered by the EN 857 hose standard. In general, the hose consists of an inner tube for the conveyed fluid, two layers of braided steel-wire reinforcement, and an outer cover that protects against the surrounding environment. The two reinforcement layers help the hose carry hydraulic pressure, while its compact construction can support tighter routing than some larger hose designs. Actual performance depends on the hose size, materials, manufacturing specification, and end connections.
Common Construction and Material Options
The inner tube is commonly made from synthetic rubber selected for compatibility with hydraulic oils and other specified fluids. The reinforcement is two braided steel-wire layers, and the outer cover is generally rubber formulated to provide protection against wear and environmental exposure. Exact compounds and cover options differ between products, so buyers should confirm them against the application rather than assume that every 2SC hose has identical resistance. A supplier can advise whether a standard cover or a requested alternative is appropriate.
Specifications Buyers Should Check
EN 857 2SC is a useful starting point, not a complete purchasing specification. A correct selection requires the nominal bore, working pressure, temperature limits, bend radius, fluid compatibility, and assembly details. These values can vary by size and manufacturer, so do not apply one pressure or bend-radius figure to the entire product family. Request the technical data sheet for the exact hose size and confirm that its stated limits cover the system’s normal and peak conditions.
Pressure, Temperature, and Bend Radius
Check both continuous working pressure and pressure surges, including any transient peaks during start-up or valve operation. The hose assembly’s rating is also affected by its fittings and assembly method, so evaluate the complete assembly rather than the hose tube alone. For temperature, typical guidance for compatible hydraulic fluids is around -40°C to +100°C, while water-based fluids may have a lower limit, commonly around +70°C. Treat these figures as general selection guidance and use the manufacturer’s rating for the actual fluid and product.
Minimum bend radius is a size-specific value that should be checked before designing the route. Bending below the stated minimum can place undue stress on the reinforcement and shorten service life. Also allow for movement, vibration, and changes in hose position during operation, rather than measuring only the static installation. If space is restricted, provide a routing sketch or dimensions when asking a supplier to review the selection.

Applications and Product Matching
DIN EN 857 2SC hoses are considered for hydraulic pressure lines in mobile machinery, industrial equipment, and systems where compact routing is important. Potential uses include hydraulic circuits on construction or agricultural equipment, machine tools, and material-handling systems, subject to pressure, temperature, fluid, and installation requirements. These are application categories, not a guarantee of suitability for every machine in that category. Confirm the equipment maker’s specification and the hose’s technical limits before substitution.
Match the Hose to the Operating Conditions
Begin with the system’s maximum operating pressure and identify any pressure spikes. Then determine the required flow and hose bore, since an unsuitable bore can affect flow velocity and system performance. Confirm the fluid type, temperature range, exposure to abrasion or weather, and whether the hose will flex repeatedly. Finally, check fitting type, end orientation, assembly length, and the space available for routing.
A Practical Selection Framework
- Document the system: Record the equipment specification, fluid, normal and peak pressure, operating temperature, and duty cycle.
- Confirm size and routing: Identify the required nominal bore and check the manufacturer’s minimum bend radius against the installation space.
- Choose materials and cover: Verify fluid compatibility and consider the actual exposure to abrasion, oil, weather, and other environmental factors.
- Specify the assembly: Provide fitting standards, thread details, orientation, overall length, and any required protective accessories.
- Review documentation: Compare the selected product’s data sheet and assembly rating with the equipment requirements before ordering.
Common Selection Mistakes
A frequent mistake is choosing a hose based only on its outside appearance or the “2SC” label. Two products sharing a standard designation may still differ in dimensions, material details, or published performance values. Buyers should also avoid assuming that a hose’s pressure rating is the same as the rating of an assembled hose with fittings. Lastly, do not force a hose into a tight route without checking bend radius, movement, and clearance.
Pricing, MOQ, and Lead-Time Considerations
Pricing depends on factors such as hose size, requested length, material and cover options, fitting configuration, order quantity, and packaging requirements. Minimum order quantities and lead times are supplier- and specification-dependent; they can also vary between standard hose and customized assemblies. For a comparable quotation, provide a complete specification and indicate whether you need bulk hose, cut lengths, or finished assemblies. Ask the supplier to confirm availability, order quantity, production timing, and any inspection or documentation requirements in writing.
Supplier Evaluation Checklist
A reliable sourcing process checks more than unit price. Ask whether the supplier can provide a current technical data sheet for the exact size, explain the product’s stated limits, and confirm fitting and assembly compatibility. Clarify how product identification, packaging, and order specifications will be handled, especially for repeat purchases. If your project has approval or traceability requirements, state them before quotation and confirm what documentation the supplier can provide.
