DIN EN 857 1SC is a compact hydraulic hose specification for applications that need a single steel-wire-braid hose with a smaller outside diameter or tighter routing than some conventional hose designs. The hose is generally built with a synthetic-rubber tube, one high-tensile steel-wire braid, and a synthetic-rubber cover. Its suitability depends on the exact hose size, working pressure, fluid, temperature, bend radius, and fitting assembly—not on the 1SC designation alone. Use this guide to check the specification and prepare the right information before requesting a quotation.

This guide is intended for hydraulic equipment manufacturers, maintenance teams, distributors, and procurement professionals comparing hose options for a project or replacement order. It is useful when a drawing or specification calls for DIN EN 857 1SC, or when you need to determine whether this hose construction fits a particular hydraulic circuit. It is not a substitute for the hose manufacturer’s technical data or an application-specific engineering review. If you are replacing an existing assembly, verify its identification and operating conditions before ordering.
DIN EN 857 1SC refers to a compact hydraulic hose type covered by the EN 857 specification. The “1” indicates one layer of steel-wire-braid reinforcement, while “SC” denotes the compact hose type. In a typical construction, a rubber inner tube carries the hydraulic fluid, the wire braid provides pressure reinforcement, and an outer rubber cover protects the hose from its surroundings. Exact material compounds and performance details can vary by manufacturer, so buyers should review the product’s technical sheet.
The tube material must be compatible with the fluid, additives, and operating conditions in the system. The steel-wire braid resists internal pressure, while the outer cover is selected to suit expected exposure such as abrasion, weather, or contact with oils. These layers have different functions, so a suitable cover does not make an incompatible tube acceptable. Ask the supplier to confirm fluid compatibility for the specific product rather than relying on a general description such as “hydraulic hose.”
The EN 857 1SC designation provides a useful starting point, but it does not give buyers every value needed to approve a hose for service. The pressure capacity, outside diameter, minimum bend radius, and other dimensions depend on the nominal bore and the manufacturer’s design. For many 1SC products, manufacturers publish an operating temperature range of -40°C to +100°C; treat this as a product specification to verify, not a universal guarantee for every fluid or assembly. Temperature limits can also depend on the fluid, exposure duration, and fitting configuration.
| Specification | What to confirm | Why it matters |
|---|---|---|
| Nominal bore and dimensions | Inside diameter, outside diameter, and tolerance for the selected size | These affect flow, routing, clearance, and connection compatibility. |
| Working pressure | Manufacturer’s rating for the exact hose size and assembly | The system’s maximum pressure must remain within the approved rating. |
| Temperature | Fluid and ambient limits listed for the product | Heat or cold can affect material performance and service suitability. |
| Bend radius | Minimum radius for the selected bore and installation | Excessive bending can damage the hose or reduce its service life. |
| Ends and assembly | Fitting type, thread, orientation, and assembly requirements | A compatible hose alone does not ensure a compatible assembly. |
Pressure data should be read carefully: working pressure is not the same as burst pressure, and neither value should be inferred from a different size in the same product family. For example, if a machine circuit operates at 180 bar, compare that requirement with the supplier’s published working-pressure rating for the exact bore and assembled configuration. Also consider pressure peaks and the system designer’s safety requirements. Do not use a burst rating as an acceptable operating limit.
DIN EN 857 1SC hoses may be considered for hydraulic circuits in mobile equipment, industrial machinery, and other systems where a compact, single-wire-braid hose construction is specified. Potential uses include pressure lines and equipment connections, provided the selected size and rating match the circuit. The standard designation alone does not confirm suitability for every machine, fluid, or installation environment. The system designer or responsible technical team should approve the final selection.

Start with the hydraulic fluid, normal operating pressure, possible pressure surges, and temperature range. Then check the required flow and inside diameter, followed by routing constraints such as bend radius, movement, vibration, and available clearance. Review environmental exposure, including abrasion, outdoor weather, and contact with chemicals or cleaning agents. Where the hose moves during operation, account for movement and provide adequate support rather than forcing the hose into a tight or twisted route.
A frequent error is selecting by hose designation alone without checking the required working pressure for the chosen size. Another is using a hose that fits the route but has an unsuitable fluid or temperature rating. Buyers can also overlook end-fitting details, assembly length, or bend radius, which may lead to installation problems even when the hose itself is correctly specified. If replacing an assembly, do not assume that its current configuration is appropriate simply because it was previously installed.
Pricing depends on factors such as hose size, order quantity, requested length, end fittings, and any packaging or documentation requirements. Minimum order quantities and lead times can vary with product availability, production planning, and the level of customization. We recommend sending a complete inquiry rather than comparing prices based on the 1SC designation alone. Include the requested quantity, delivery destination, and target schedule so suppliers can respond against the same requirements.
Before placing an order, ask whether the supplier can provide product data for the exact bore and confirm the hose construction, pressure rating, temperature limits, and dimensions. Clarify whether the quotation covers hose only or a finished assembly with fittings, and specify what inspection or product documents are required. Check that the supplier understands your connection standards and application conditions. Where a requirement is not confirmed in writing, resolve it before production or shipment.
At Hengshui Xinchi Hose Manufacturing Co., Ltd., we supply rubber hose products for B2B buyers and can discuss DIN EN 857 1SC requirements based on the details provided. To help us assess your request, share the nominal bore, required length, fluid, operating pressure and temperature, fitting details, quantity, and destination. We can then clarify the relevant product information and quotation scope for your application. Final suitability should be confirmed against the selected product data and your equipment requirements.
DIN EN 857 1SC is a compact hydraulic hose type with one steel-wire-braid reinforcement layer, but the designation by itself is not enough to approve a purchase. Confirm the exact size-specific pressure rating, temperature and fluid compatibility, bend radius, dimensions, and complete fitting assembly. The most useful next step is to prepare your operating conditions and connection details, then request technical data and a quotation for the specific configuration. Contact Hengshui Xinchi Hose Manufacturing Co., Ltd. with those requirements to discuss the appropriate product options for your project.
