DIN EN857 2SC Hydraulic Hoses: Specifications, Applications, and Selection Guide
DIN EN 857 2SC Hydraulic Hoses: Specifications, Applications, and Selection Guide
DIN EN 857 2SC hydraulic hose is a compact, high-pressure hose built with two steel-wire reinforcement braids. It is used to carry hydraulic fluids in equipment where a smaller outside diameter or tighter routing is useful, provided its pressure, temperature, fluid compatibility, and bend-radius limits suit the system. To select it safely, compare the hose’s size-specific data sheet with the actual operating conditions rather than relying on the 2SC designation alone.

Who This Guide Is For
This guide is for hydraulic equipment manufacturers, maintenance teams, distributors, and procurement professionals evaluating DIN EN 857 2SC hose for a new assembly or replacement. It explains what the designation means, where this hose may be suitable, and which details to confirm before ordering. Final specifications should be checked against the selected manufacturer’s current technical documentation.
What DIN EN 857 2SC Means
Standard and construction
EN 857 identifies a European hose standard covering compact wire-braid hydraulic hose types. In the 2SC designation, “2” refers to two reinforcement braids and “SC” identifies the compact hose type. A typical assembly comprises a synthetic-rubber inner tube, two high-tensile steel-wire braids, and a protective outer cover.
The inner tube is selected for contact with hydraulic fluid, while the reinforcement carries pressure loads and the cover helps protect against external exposure. Exact rubber compounds, cover properties, dimensions, and performance values depend on the manufacturer’s product construction. For this reason, two hoses marked 2SC should not be assumed to have identical specifications or interchangeability.
Key specifications to verify
The standard designation is a starting point, not a complete purchasing specification. Confirm the nominal bore, inside and outside diameters, working pressure, minimum burst pressure where specified, impulse performance, minimum bend radius, temperature range, and fluid compatibility for the exact size. Also check the fitting type and crimping instructions for the hose assembly.
| Specification | Why it matters | What to confirm |
|---|---|---|
| Hose size | Controls flow capacity and compatibility with the system connections. | Nominal bore and dimensional data for the selected size. |
| Working pressure | Must accommodate the system’s pressure, including relevant operating conditions. | Manufacturer’s rating for that size and assembly. |
| Temperature | Heat and cold can affect hose materials and service life. | Limits for the hose, fluid, and operating environment. |
| Bend radius | Excessive bending can strain reinforcement and restrict flow. | Minimum radius and routing guidance from the product data sheet. |
| Fluid and cover | Material compatibility and external exposure affect suitability. | Fluid type, cover requirements, and environmental conditions. |
Applications and Material Considerations
DIN EN 857 2SC hose may be considered for hydraulic circuits in mobile machinery, industrial equipment, and other systems that require a flexible pressure line. Its compact construction can be helpful where installation space is restricted compared with some conventional two-wire-braid hose designs. Suitability still depends on the pressure and routing requirements of the specific circuit.
Hydraulic oil is a common application, but fluid compatibility must be confirmed for the actual fluid formulation and hose compound. Water-based fluids, lubricants, and other media can have different material requirements. The outside cover should also be selected with the installation environment in mind, including possible exposure to abrasion, oil, weather, heat, or chemicals.
Temperature figures should be treated as product-specific limits. Some manufacturers list a general operating range of approximately -40°C to +100°C for compatible petroleum-based hydraulic fluids, while water-based fluids may have a lower stated upper limit, such as +70°C. These figures are examples of commonly published limits, not a guarantee for every 2SC product; check the relevant technical sheet and fluid guidance before use.
A Practical Selection Framework
1. Record the operating conditions
Start with the system’s maximum working pressure, pressure fluctuations, operating temperature, fluid, and expected duty cycle. Consider the environment around the hose as well, including contact with moving parts, heat sources, abrasion, and weather. If pressure peaks or temperature excursions are possible, include them in the information supplied to the hose manufacturer or assembly provider.
2. Confirm size and routing
Identify the required nominal bore and connection details from the equipment specification or existing assembly. Check that the selected hose meets the required flow needs and that its outside diameter fits the available space. Route it without twisting, kinking, or bending below the manufacturer’s minimum bend radius.

3. Match the hose and fittings as an assembly
Hose, fittings, and crimp dimensions must be compatible as a tested or manufacturer-approved assembly. Do not assume that fittings from another hose series can be used simply because the nominal size is the same. Follow the assembly provider’s instructions for fitting selection, crimping, inspection, and installation.
4. Review documentation and traceability
Before approval, request the product data sheet and confirm that it applies to the exact size and construction being quoted. Ask what inspection, marking, and batch or lot information is available for the order. For regulated or safety-critical equipment, align the documentation request with your own quality and compliance requirements.
Pricing, MOQ, and Lead-Time Questions
Price can vary with hose size, order quantity, requested cut lengths, packaging, fittings, and documentation requirements. A quote for bulk hose may differ from a quote for finished assemblies, so specify which product you need. If your project requires special cover properties or other customization, ask whether the request is available for the chosen construction.
Minimum order quantity and lead time depend on the selected specification, stock status, production schedule, and shipping destination. We recommend requesting these details with the quotation rather than assuming a standard quantity or delivery window. For planning purposes, provide your target order quantity, preferred delivery date, and any required inspection or packaging details.
Supplier Evaluation Checklist
- Can the supplier provide current specifications for the exact hose size and construction?
- Are the pressure, temperature, bend-radius, and fluid-compatibility limits clearly stated?
- Can the supplier confirm fitting compatibility and provide assembly guidance where needed?
- Are marking, packaging, inspection documents, and traceability requirements addressed?
- Are quotation validity, minimum order quantity, lead time, and shipping terms clear?
As a manufacturer and supplier of rubber products, Hengshui Xinchi Hose Manufacturing Co., Ltd. can discuss DIN EN 857 2SC hydraulic hose requirements with buyers evaluating hose supply or project-specific options. To support a useful quotation, share the required size, working pressure, fluid, temperature range, hose length or assembly details, quantity, and delivery destination. We can then review the request against the available product information and clarify any details that need confirmation.
Common Selection Mistakes
One frequent mistake is choosing by hose designation alone without checking the pressure rating for the required size. Another is overlooking the minimum bend radius or allowing the installed hose to twist, rub against nearby components, or sit too close to a heat source. Each of these conditions can create an unsuitable installation even when the hose type appears correct on paper.
Buyers should also avoid treating a published temperature range as universal across fluids and hose brands. The stated limit may depend on the fluid, exposure duration, and product construction. When replacing an existing hose, verify its size, fittings, routing, and system duty instead of assuming that a visually similar product is a direct substitute.
Key Takeaways and Next Steps
DIN EN 857 2SC is a compact hydraulic hose type with two steel-wire reinforcement braids, intended for applications where its product-specific pressure and environmental limits are suitable. Selection depends on more than the standard name: size, working pressure, temperature, fluid compatibility, bend radius, fittings, and installation conditions all need review. Published figures such as -40°C to +100°C, or a lower upper limit such as +70°C for certain water-based fluids, must be verified for the exact product.
To move forward, prepare your operating-condition details and request the data sheet, assembly compatibility information, price, MOQ, and lead time for the required specification.
