DIN EN857 1SC Hydraulic Hoses: A Buyer’s Guide to Specifications and Applications
DIN EN 857 1SC is a compact hydraulic hose type made with a synthetic-rubber inner tube, one high-tensile steel-wire braid and a protective rubber cover. Buyers typically consider it for hydraulic circuits where a single-wire-braid hose meets the system’s pressure requirements and a compact installation is useful. The right choice depends on hose size, working pressure, fluid, temperature, routing and compatible fittings—not on the standard designation alone. In this guide, we explain what to check before requesting a quotation or placing an order.
Who This Guide Is For
This guide is intended for equipment manufacturers, hydraulic system designers, maintenance teams, distributors and industrial procurement professionals. It is useful when comparing hose specifications, sourcing replacement assemblies or preparing a request for quotation. It is not a substitute for the hose manufacturer’s technical data or the equipment manufacturer’s requirements. Confirm the final selection against the complete operating conditions of your system.
What DIN EN 857 1SC Means
Construction and basic function
DIN EN 857 1SC identifies a hydraulic hose construction with one steel-wire braid reinforcement. The inner tube is selected for compatibility with the intended hydraulic fluid, while the reinforcement carries pressure loads and the outer cover helps protect against external conditions such as abrasion and weathering. “Compact” describes the hose type, but actual outside diameter and minimum bend radius vary by nominal size and product design.
The hose carries pressurized fluid between components such as pumps, valves, cylinders and motors. The steel braid supports the hose under pressure, while the flexible construction allows routing between equipment connections. Hose performance depends on the complete assembly, including the hose, fittings, crimp dimensions and installation. A correct hose type cannot compensate for an incorrectly specified or assembled connection.
Common specification points
DIN EN 857 1SC product lines are commonly offered across nominal bore sizes from DN 6 to DN 25, but the available range depends on the supplier. Many manufacturers publish a temperature range of approximately -40°C to +100°C for compatible hydraulic oil service; this should be treated as a product-specific value, not a universal guarantee. For some product lines, published limits for water-based fluids or air are lower, such as +70°C for water-based fluids and +60°C for air. Check the supplier’s current datasheet for the exact hose, fluid and duty cycle.
| Specification | What to verify |
|---|---|
| Standard and hose type | Confirm that the required hose is DIN EN 857 1SC, rather than a visually similar construction. |
| Nominal bore and dimensions | Match the hose inside diameter to system flow needs and check outside diameter for routing and clamps. |
| Pressure rating | Confirm working pressure for the selected size, including the system’s peak and transient pressures. |
| Temperature and fluid | Check compatibility for the actual fluid, temperature range and operating conditions. |
| Bend radius and fittings | Review the product’s minimum bend radius and confirm that end connections fit the equipment. |
Applications and Hose Matching
Buyers may consider 1SC hoses for hydraulic lines in mobile equipment, industrial machinery and other systems where a single-wire-braid construction is specified. Suitability depends on the pressure and environmental conditions of the particular circuit. A hose intended for a sheltered machine installation may face different abrasion, weather, heat or movement demands from a line routed on outdoor equipment. Identify those conditions before comparing prices.
Match the hose to the operating circuit
Start with the machine or system documentation, then confirm the hose size and pressure requirements for the specific line. Pressure must be checked at the relevant operating conditions, including surges where applicable; do not select by normal pressure alone. Compare the required bend radius with the space available in the installation, and ensure the hose will not be twisted, crushed or forced into a tight curve. If the route moves during operation, include that movement in the review.

Fluid compatibility also matters. Hydraulic oils, water-based fluids and other media can place different demands on the tube and cover materials, so do not assume that a hose suitable for one medium is suitable for another. Confirm whether the external environment includes oil exposure, sunlight, weather, heat or repeated contact with nearby components. When the fluid or conditions are unusual, provide the supplier with the product name and operating details for review.
A Practical Selection Framework
- Document the application. Record the equipment, circuit location, fluid type, normal temperature and ambient conditions.
- Confirm size and pressure. Specify nominal bore, required working pressure and any known pressure peaks; ask for the rating for the exact hose size.
- Check routing constraints. Share the available installation space, bend requirements, hose length and movement, if any.
- Specify the assembly ends. Identify fitting type, thread or connection standard, orientation and required assembly length.
- Review the datasheet and quotation. Ensure the quoted hose and fittings match the requested construction and duty conditions before ordering.
These checks help turn a general request such as “1SC hose” into a purchasing specification that suppliers can evaluate. Where an existing assembly is being replaced, provide clear measurements and fitting details rather than relying only on appearance. If the old hose has failed, document the failure location and operating conditions as well. This information can help distinguish a specification mismatch from installation damage or another system issue.
Common selection mistakes
- Choosing from the standard designation without checking the working-pressure rating for the required size.
- Using a nominally compatible hose with an unverified fluid or temperature range.
- Ignoring bend radius, movement, abrasion or installation clearance.
- Assuming that fittings from different hose systems are interchangeable without confirmation.
- Comparing quotations that use different lengths, fittings, packaging or documentation requirements.
Pricing, MOQ and Lead-Time Considerations
The purchase price of a 1SC hose or assembly depends on the size, length, fitting configuration, order quantity and any requested inspection or packaging arrangements. Raw-material and supply conditions can also affect quotations, so buyers should compare offers using the same specification and validity period. Minimum order quantities and production lead times vary by supplier, product configuration and current availability. Request these details directly rather than assuming that a standard hose size is always available from stock.
For a fair sourcing comparison, ask suppliers to quote the same hose construction, sizes, pressure requirements, end connections and delivery destination. Clarify whether the offer is for hose only or complete assemblies, and identify any required batch identification or product documentation. If the project has a delivery deadline, state the required quantity and target shipment date in the inquiry. This allows suppliers to respond against the actual purchasing need.
Supplier Evaluation Checklist
A reliable supplier should be able to explain which product specification is being offered and provide relevant technical information for buyer review. Ask for the datasheet, pressure rating by size, temperature and fluid guidance, dimensions, bend radius and fitting compatibility. Confirm how the supplier handles custom lengths, assembly requirements, packaging and order scheduling. Evaluate the clarity and completeness of the response alongside the quoted price.

Key Takeaways and Next Steps
DIN EN 857 1SC is a single-steel-wire-braid compact hydraulic hose type, but the designation alone does not establish that a hose is suitable for every circuit. Buyers should verify pressure by size, fluid and temperature compatibility, bend radius, routing and fittings before purchase. Published operating limits are product-specific, so confirm them with the supplier’s datasheet rather than applying a typical range to every hose. To move forward, prepare your application details and request a quotation that clearly identifies the hose and assembly requirements.
