DIN EN 857 2SC Hydraulic Hoses: Specifications, Applications, and Selection Guide
DIN EN 857 2SC is a compact hydraulic hose type reinforced with two steel-wire braids. Buyers typically consider it where a flexible, high-pressure hose is needed and installation space or routing radius matters. The correct choice depends on the hose size, working pressure, fluid, temperature, fittings, and installation conditions—not the standard designation alone. In this guide, we explain what to check before specifying or requesting a quotation.

Key Takeaways
- “2SC” identifies a compact hose construction with two steel-wire braid reinforcement layers.
- Confirm the required working pressure for the exact hose size against the supplier’s product data; pressure ratings vary by size and construction.
- Match the inner tube, cover, fittings, and temperature range to the hydraulic fluid and operating environment.
- For a quotation, provide size, pressure, fluid, temperature, length, fitting details, and expected order quantity.
What Is a DIN EN 857 2SC Hydraulic Hose?
DIN EN 857 2SC is a category of compact hydraulic hose specified under the EN 857 standard. Its reinforcement consists of two layers of steel-wire braid, which help the hose contain pressure while remaining flexible enough for hydraulic equipment routing. A typical assembly also has a synthetic-rubber inner tube and a protective outer cover, although the exact rubber compounds and cover properties depend on the product design.
The “2SC” designation does not give a single working-pressure value that applies to every size. The allowable pressure, minimum bend radius, outside diameter, and other dimensions must be checked in the manufacturer’s technical data for the selected size. Treat the standard as a product specification framework, and verify that the hose and fittings are suitable for the actual system.
Construction, Specifications, and Options
Typical Construction
The inner tube carries the hydraulic fluid and must be compatible with the fluid in use. Two steel-wire braids provide the pressure reinforcement, while the outer cover protects the reinforcement from the surrounding environment. Cover options and compound formulations can differ, so we recommend confirming resistance requirements such as abrasion, weather, ozone, or exposure to oils and chemicals with the supplier.
Specifications to Confirm
| Specification | What to verify | Why it matters |
|---|---|---|
| Hose size | Nominal bore and outside diameter from the product data | Size affects flow, fit, pressure capability, and routing space. |
| Working pressure | Rating for the exact hose size and assembly | The system’s maximum operating pressure must remain within the assembly rating. |
| Temperature | Hose, fluid, and environment limits stated by the manufacturer | Heat or cold outside the rated range can affect hose life and performance. |
| Fluid compatibility | Inner-tube suitability for the hydraulic medium | Compatibility depends on the fluid formulation and service conditions. |
| Fittings and assembly | End type, thread, material, crimp specification, and length | A suitable hose does not guarantee a suitable finished assembly. |
As a practical reference, a hose identified as DN 10 has a nominal bore of 10 mm; this is not necessarily its outside diameter. Some manufacturers list a typical operating temperature range of -40°C to +100°C for particular 2SC products, but this should not be treated as a universal rating. Actual limits can depend on the hose model, hydraulic fluid, and exposure conditions, so use the applicable product datasheet.
Applications and Hose Matching
DIN EN 857 2SC hoses are used in hydraulic lines where a compact, reinforced hose is appropriate. Potential applications include mobile machinery, agricultural equipment, material-handling systems, and industrial hydraulic equipment. Whether a particular hose is suitable depends on the equipment manufacturer’s requirements and the operating pressure, movement, temperature, and fluid involved.
When space is restricted, the compact form may be useful, but do not assume that every 2SC hose has the same outside diameter or bend radius. Compare the supplier’s dimensions with the route and check that the hose will not be forced into a tighter bend than its stated minimum. Consider movement during operation as well as the static position during installation.
How to Select a DIN EN 857 2SC Hose
1. Establish the Operating Requirements
Record the maximum system pressure, pressure surges if known, operating temperature, hydraulic fluid, and ambient conditions. Identify whether the line is stationary or flexes during equipment operation. If the system designer has specified a hose standard or model, use that information as the starting point rather than substituting based on appearance.
2. Choose the Size and Check the Pressure Rating
Confirm the required nominal bore and the available routing space. Then check the manufacturer’s pressure table for that exact size, including the stated working pressure and any relevant limits. Do not use a rating from a different diameter or assume that a hose’s burst pressure is its permissible operating pressure.

3. Specify the Complete Assembly
Provide the required overall length, fitting styles, thread standards, orientation, and assembly details. If the assembly has angled fittings, indicate their orientation or provide a drawing. Ask the supplier to confirm that the hose, fittings, and assembly method are matched as a system.
4. Review Installation Conditions
Check bend radius, abrasion points, heat sources, vibration, and potential contact with moving parts. Select protective measures or a different routing arrangement where the installation creates a known exposure. Good routing reduces avoidable stress but does not replace correct sizing or pressure selection.
Common Selection Mistakes
- Choosing by standard name alone: The designation does not replace checking the product’s size-specific pressure and dimensional data.
- Using a hose outside its temperature or fluid limits: Confirm the exact medium and service conditions with the supplier.
- Ignoring fittings: Thread type, sealing method, and crimp compatibility affect the finished assembly.
- Forcing a tight route: Compare the installation path with the stated minimum bend radius and account for movement.
- Mixing product data: Do not apply specifications from one model or size to another without confirmation.
Pricing, MOQ, and Lead-Time Considerations
Pricing depends on factors such as hose size, pressure specification, cover requirements, order quantity, cut length, and fittings. Minimum order quantities and production or shipping lead times also vary by supplier and order configuration. For an accurate quotation, share the required specification and delivery destination, and ask which values are confirmed for the exact product offered.
For repeat purchasing, buyers can reduce specification ambiguity by keeping a controlled drawing or hose schedule. Record the product designation, nominal bore, assembly length, end connections, and revision date. Before approving a substitute, compare its technical data with the original requirement and obtain confirmation from the equipment designer where necessary.
Supplier Evaluation Checklist
Ask the supplier for a datasheet covering the selected size, working pressure, temperature limits, dimensions, and bend radius. Confirm that the stated product construction and fitting options meet your specification, and request clarification where values or standards are not explicit. For an assembly order, confirm length tolerances, fitting orientation, packaging, order quantity, and delivery schedule before placing the purchase order.

Conclusion: What Should You Specify?
DIN EN 857 2SC is a compact hydraulic hose construction with two steel-wire braid reinforcement layers, but selecting the right product requires more than identifying the standard. Confirm the exact size-specific pressure and dimensional data, fluid and temperature suitability, routing requirements, and compatible fittings. These checks help buyers evaluate the hose and assembly against the actual equipment needs.
Your next step is to prepare a complete specification or hose sample reference and request a quotation with the relevant technical data. If any operating condition is unknown, identify it as an open point rather than assuming a rating.
