DIN EN 857 1SC is a compact hydraulic hose specification for applications that need a single steel-wire braid reinforcement and a smaller bend radius than many conventional textile-reinforced hoses. To select one correctly, compare the required working pressure, hose size, fluid compatibility, temperature range, bend radius, and end connections with the supplier’s technical data. The EN 857 1SC designation alone does not confirm that a particular hose assembly is suitable for every machine or operating condition. We recommend assessing the complete assembly and its operating environment before ordering.

This guide is intended for hydraulic equipment manufacturers, distributors, maintenance teams, and procurement professionals evaluating DIN EN 857 1SC hose. It is useful when specifying a replacement hose, comparing compact hose options, or preparing an RFQ for a supplier. The information provides a selection framework rather than a substitute for a machine manufacturer’s requirements or a hose manufacturer’s datasheet. Where operating conditions are demanding, confirm the selection with a qualified application engineer.
DIN EN 857 1SC is a standard designation for a compact hydraulic hose type. A typical construction includes an oil-resistant synthetic rubber inner tube, one high-tensile steel-wire braid reinforcement, and a protective synthetic rubber cover. The inner tube carries the hydraulic fluid, the reinforcement helps contain pressure, and the cover protects the hose from external conditions such as abrasion and weather exposure.
The compact design can help when routing space is limited or a tighter bend is required, compared with some conventional hose constructions. However, “compact” does not mean the hose can be bent without limits. The manufacturer’s minimum bend radius and installation instructions still apply, and the hose must not be twisted or forced into an unsuitable route.
Product details can vary between manufacturers, so treat the figures below as selection checkpoints rather than universal values. Many EN 857 1SC products are offered in nominal bore sizes from DN 6 to DN 25, and manufacturers commonly state an operating temperature range around -40°C to +100°C. These values should be checked against the exact product datasheet, especially when the fluid, ambient temperature, or duty cycle differs from standard hydraulic service.
| Specification | What to confirm | Why it matters |
|---|---|---|
| Nominal bore and outside diameter | Required flow capacity, connection size, and available routing space | A mismatch can affect system flow, installation, or fitting compatibility. |
| Working and impulse pressure | Pressure ratings for the selected hose size and assembly | Pressure capability is size-dependent and must suit the machine’s operating conditions. |
| Temperature range | Permitted fluid and ambient temperatures for the selected hose | Temperature can affect hose materials and service suitability. |
| Minimum bend radius | Published value for the selected size | Excessive bending can stress the reinforcement or shorten service life. |
| Fluid compatibility and fittings | Fluid type, fitting material, end style, and assembly method | The hose and its connections must work as a compatible system. |
EN 857 1SC may be considered for hydraulic lines on mobile equipment, industrial machinery, and other systems where a compact, wire-braided hose is appropriate. The actual fit depends on pressure peaks, vibration, fluid, temperature, exposure, and installation geometry. A product that matches a nominal size may still be unsuitable if the routing causes tight bends or if the operating pressure exceeds its rating.
Compare 1SC with other hose constructions based on the duty, not only on outside diameter or purchase price. A single-wire-braid compact hose may suit some applications, while higher-pressure or more demanding service may require a different reinforcement construction. Where the hose is exposed to severe abrasion, chemicals, high temperatures, or unusual fluids, request confirmation that the specific tube and cover materials are suitable.
Record the system’s normal and peak pressure, operating temperature, ambient temperature, hydraulic fluid, and duty cycle. Include transient pressure or frequent pressure changes if they are part of normal operation. Do not select solely from the machine’s nominal pressure if the hose line can experience higher peaks.

Identify the required nominal bore, connection thread or interface, and available installation space. Use the equipment specification or the existing assembly information as a starting point, but inspect the application before treating an old hose as the correct reference. If flow requirements are uncertain, consult the system designer or equipment manufacturer rather than estimating from hose appearance.
Compare the planned hose path with the minimum bend radius stated on the datasheet. Allow for movement, vibration, and maintenance access, and avoid sharp edges or contact with hot components. A routing plan that meets the bend limit in a static position may still need review if the machine moves during operation.
Provide the supplier with hose type, size, length, end fittings, orientation, and any protective sleeves or covers required. State whether you need bulk hose or finished assemblies, and identify any assembly or documentation requirements. Confirm the fitting compatibility and assembly method before approving a production order.
Pricing for EN 857 1SC depends on factors such as hose size, order quantity, requested length, fittings, protection options, and packaging. Minimum order quantities and lead times vary by supplier, stock position, and whether the order is for hose only or custom assemblies. Rather than relying on a general market estimate, request a dated quotation that identifies the exact specification and delivery terms.
For a comparable quotation, send the same technical requirements to each supplier. Ask them to identify the offered hose construction, pressure rating by size, temperature limits, bend radius, available sizes, and applicable documentation. If you have a target delivery date or recurring demand, state it in the inquiry so the supplier can clarify availability and production planning.
At Hengshui Xinchi Hose Manufacturing Co., Ltd., we support B2B inquiries for hydraulic rubber hose products, including requests that require review of size, application conditions, and supply format. Share your operating details and connection requirements so our team can check the requested specification against the available product information. We encourage buyers to verify all critical ratings and assembly details before installation.
DIN EN 857 1SC is a compact, single-steel-wire-braid hydraulic hose type that can be appropriate when its pressure capability, dimensions, materials, and routing limits match the application. Begin with system pressure, temperature, fluid, bore, bend radius, and fittings, then validate the selection using the exact manufacturer’s datasheet. Do not assume that every product carrying the 1SC designation has identical ratings or is suitable for every hydraulic circuit.
For your next step, prepare an RFQ with the hose size, required length, operating conditions, connection details, quantity, and delivery target. Hengshui Xinchi Hose Manufacturing Co., Ltd. can review those requirements and provide product information for your evaluation. A complete specification helps reduce quotation ambiguity and supports a more reliable purchasing decision.
