DIN EN 857 1SC is a compact hydraulic hose type designed for conveying hydraulic fluids in systems that need a smaller outside diameter or tighter routing than many conventional wire-braid hoses. Its construction uses one high-tensile steel-wire braid, with an inner tube and outer cover selected for the intended fluid and service conditions. To choose the right hose, match its nominal bore, working pressure, temperature range, bend radius, fluid compatibility, and end connections to the equipment requirements. At XINCHI, we recommend confirming the complete hose assembly specification—not just the 1SC designation—before requesting a quotation.

This guide is for hydraulic equipment manufacturers, maintenance teams, distributors, and industrial buyers evaluating DIN EN 857 1SC hose. It is particularly useful when a project requires a compact hose route or when an existing hose must be identified and replaced. The information supports initial product selection, but it does not replace equipment documentation or the manufacturer’s technical data for a specific hose assembly. Buyers should confirm all critical values before installation.
DIN EN 857 1SC is a hose type specified within the DIN EN 857 family of hydraulic hose standards. A typical 1SC hose has an oil-resistant synthetic-rubber inner tube, one steel-wire braid reinforcement, and a protective synthetic-rubber outer cover. The reinforcement helps the hose contain pressure, while the inner tube and cover are selected to suit the fluid and external environment. Exact materials and performance limits can vary by product, so buyers should check the supplier’s documentation.
The “1” in 1SC refers to a single wire-braid reinforcement layer, while “SC” denotes the compact hose type. Compact construction can support installation in restricted spaces, but it does not mean the hose can be bent below its specified minimum bend radius. Nor does the designation alone determine a safe working pressure for every diameter. Confirm the rating for the specific hose size and assembly.
Product catalogues commonly list 1SC hoses in nominal bore sizes from approximately 6 mm to 25 mm, although the range may differ between manufacturers. A common stated temperature range for hydraulic service is -40°C to +100°C, subject to the hose construction, fluid, and operating conditions. These are reference points, not a substitute for the specific product data sheet. Pressure ratings, dimensions, and bend radii must be checked size by size.
| Specification | What to Confirm | Why It Matters |
|---|---|---|
| Nominal bore | Hose size and internal diameter required by the system | Supports flow requirements and connection compatibility |
| Working pressure | Product rating for the selected bore, including pressure peaks where applicable | Prevents selection based only on the hose-type name |
| Temperature | Fluid and ambient operating temperatures against the supplier’s stated limits | Temperature can affect hose materials and service suitability |
| Bend radius | Minimum radius stated for the selected size | Helps avoid excessive bending during installation or operation |
| Fluid and cover compatibility | Fluid type, external exposure, and any special environmental conditions | Confirms that the materials suit the actual application |
DIN EN 857 1SC may be considered for hydraulic circuits in mobile equipment, industrial machinery, and other systems where a compact single-wire-braid hose meets the equipment’s pressure and environmental requirements. Potential uses include connecting actuators, valves, and hydraulic power components. Suitability depends on the actual pressure, fluid, temperature, movement, and installation route. The application name alone is not enough to confirm a match.
Compare 1SC with other hose constructions when the system has unusual pressure demands, severe external exposure, frequent flexing, or a routing path that may exceed the hose’s bend limits. A different reinforcement or cover may be more appropriate depending on the application and the manufacturer’s published ratings. Avoid replacing a hose with a different type solely because its outside diameter appears similar. Verify the assembly’s pressure rating, fittings, and dimensional compatibility first.

Start with the equipment manufacturer’s hose specification or the existing assembly markings. Record the nominal bore, required length, end-fitting types, working pressure, fluid, and operating temperature. Also note whether the hose is stationary, moves during operation, or is exposed to abrasion, weather, heat, or other external conditions. If the original specification is unavailable, have a qualified technician assess the system before ordering.
Match the selected hose size to the pressure rating shown in the supplier’s data, and account for the operating conditions specified by the equipment manufacturer. Consider pressure surges if they are part of the system’s duty cycle; do not treat a hose-type designation as a pressure value. Confirm that the inner tube is suitable for the hydraulic fluid and that the cover fits the external environment. Ask the supplier to clarify any limits that are not explicit in the documentation.
Measure the route and confirm the hose can be installed without twisting, stretching, or bending below its stated minimum radius. Check that the fittings match the equipment ports, thread or sealing type, orientation, and assembly requirements. Where the hose moves, include the movement path in the review rather than measuring only the static distance. A drawing or clear photographs can help suppliers assess routing and connection details.
Specify whether you need hose only or a finished hose assembly with crimped fittings. For assemblies, request confirmation that the hose and fittings are compatible and ask what inspection or traceability documents are available for the order. Keep the approved specification with the equipment records so replacement orders can be matched consistently. Any testing or compliance statement should be confirmed against the supplier’s actual documentation.
The price of a 1SC hose or assembly depends on factors such as bore, length, order quantity, fitting type, material requirements, and packaging. Minimum order quantities and lead times vary by supplier, stock position, and whether the order is standard or customized. For a useful quotation, provide the hose size, requested standard, quantity, length, fittings, fluid, operating conditions, and destination. If the specification is still being developed, ask for a quotation based on clearly stated assumptions and request confirmation before production.
DIN EN 857 1SC is a compact hydraulic hose type with one steel-wire braid, but the designation alone cannot confirm suitability for a particular machine. Choose by matching the exact hose size and product rating to system pressure, temperature, fluid, bend radius, routing, and fittings. Then verify the finished assembly requirements and the documentation available from the supplier. For a quotation from XINCHI, share your required size, length, quantity, fittings, operating conditions, and any existing hose markings so we can review the specification with you.
