DIN EN 857 1SC Hydraulic Hoses: Specifications, Applications, and Selection Guide

DIN EN 857 1SC is a compact hydraulic hose specification for applications that need a single steel-wire-braided hose construction. It is commonly considered where installation space or routing flexibility matters, but suitability depends on the hose size, working pressure, fluid, temperature, fittings, and operating conditions. Buyers should confirm the required values against the supplier’s datasheet and the applicable standard edition rather than choosing by the “1SC” designation alone. This guide explains the construction, typical uses, and practical checks for specifying a hose.

Key Takeaways

• EN 857 1SC identifies a compact, one-wire-braid hydraulic hose type; it does not define every product-specific rating or fitting option.
• Working pressure and minimum bend radius vary by nominal bore, so check the data for the exact size you need.
• Confirm compatibility with the hydraulic fluid, temperature, pressure cycles, environment, and end connections before ordering.
• For a quotation, provide your hose size, operating conditions, required length, fitting details, and quantity.

Who This Guide Is For

This guide is intended for hydraulic equipment manufacturers, maintenance teams, distributors, and procurement professionals sourcing hose for machinery or replacement programs. It is useful when comparing a compact one-wire-braid hose with other hydraulic hose constructions or when checking whether an existing specification is complete. It is not a substitute for an engineering review of the machine circuit or the hose manufacturer’s technical documentation. Where failure could cause injury, equipment damage, or environmental harm, final selection should follow the equipment maker’s requirements and applicable safety procedures.

What DIN EN 857 1SC Means

Construction and function

EN 857 1SC describes a hydraulic hose construction with one high-tensile steel-wire braid reinforcement layer. A typical hose includes an inner tube selected for hydraulic-fluid service, the reinforcement layer, and an outer cover intended to protect the assembly from its operating environment. The exact compound formulation and cover properties can differ by manufacturer, so request product-specific information where oil compatibility, abrasion, weather, or other exposures matter.

The reinforcement helps the hose contain hydraulic pressure, while the flexible construction allows routing between components that move or vibrate. “Compact” generally refers to a design intended to offer a smaller outside diameter or tighter routing than some conventional hose constructions of a comparable size. It does not mean the hose can be bent below its specified minimum bend radius or used above its rated pressure. Always compare the working-pressure rating for the selected bore with the system’s maximum pressure, including relevant pressure surges.

Specifications to verify

Do not treat the standard designation as a complete purchase specification. The relevant datasheet should identify the nominal bore, outside diameter where needed, working pressure, minimum bend radius, temperature limits, and any applicable dimensional or performance requirements. For example, a product may be listed for a temperature range of -40°C to +100°C for certain hydraulic-fluid applications, but the permitted range can depend on the hose construction, fluid, and manufacturer’s instructions.

Pressure ratings also depend on hose size and product design. A rating shown for one nominal bore must not be applied to another, and the hose’s working pressure is not the same as its burst pressure. Some hose specifications use a burst-to-working-pressure ratio such as 4:1; buyers should confirm the required ratio and the tested values for the specific product rather than assume that every listing uses identical criteria. Ask for the manufacturer’s current technical sheet when a project requires documented conformity.

Applications and Fit

DIN EN 857 1SC hoses may be considered for hydraulic lines on mobile and industrial equipment, including systems where compact routing is useful. Potential applications include machine tools, agricultural or construction equipment, and general hydraulic assemblies, subject to the pressure and environmental demands of each circuit. These examples describe possible use cases, not a guarantee that one hose specification fits every machine in those categories. The equipment manufacturer’s instructions remain the starting point for replacements and new designs.

Check the complete duty cycle, not only the normal operating condition. Relevant factors include peak pressure, pressure pulsation, temperature changes, vibration, abrasion, exposure to sunlight or chemicals, and proximity to hot surfaces. Also consider whether the line carries mineral oil, a water-based fluid, or another medium, since compatibility can vary between inner-tube compounds. Where conditions fall outside the product datasheet, request a technical review before purchase.

Selection Framework for Buyers

1. Define the hose size and pressure requirement

Identify the required nominal bore and confirm the connection sizes at both ends. Then record the system’s maximum operating pressure and any known surge or pulsation conditions. Select only a hose whose documented working-pressure rating for that exact size meets the equipment requirement, with any design margin determined by the responsible engineer. Never use a higher rating from a different hose size as a substitute.

2. Check routing, bend radius, and temperature

Measure the available installation space and routing path, including movement during machine operation. Compare the proposed route with the hose’s specified minimum bend radius; a tight bend can place unnecessary stress on the reinforcement and connections. Confirm both the ambient and fluid temperatures, including short-duration extremes, against the supplier’s stated limits. If the hose runs near heat sources or in cold outdoor conditions, provide those details when requesting a recommendation.

3. Match the fluid and the environment

Tell the supplier the exact hydraulic fluid type and any additives or cleaning agents that may contact the hose. Specify whether the assembly will face abrasion, moisture, outdoor exposure, or chemical contact. A cover selected for one environment may not be appropriate for another, and a general description such as “oil resistant” may not answer every compatibility question. Request written confirmation when fluid or exposure compatibility is critical.

4. Specify the complete assembly

A hose assembly is only as useful as the connection details supplied with it. Provide fitting type, thread standard, orientation, end configuration, assembly length, and any protective sleeve or guard requirement. Clarify whether length is measured between fitting ends or by another convention used in your drawing. If the hose is a replacement, share the equipment part number or a dimensioned drawing where available, while still verifying the pressure and material requirements.

Materials, Options, and Product Documentation

Hose material options may include different inner-tube or cover compounds, depending on the supplier’s product range and the application. The correct option should be chosen from documented compatibility and performance information, not color or appearance alone. Buyers can also ask about cover markings, packaging, cut lengths, and available end fittings when these affect installation or inventory handling. Any requested customization should be confirmed in writing before the order is released.

For dependable comparison between offers, request the same information from each supplier: applicable standard and edition, size, working pressure by size, temperature range, minimum bend radius, fluid compatibility guidance, and fitting specifications. Ask whether the quoted item is a hose only or a finished assembly. If inspection records or other quality documents are required by your purchasing process, state that requirement at quotation stage and confirm what the supplier can provide.

Pricing, MOQ, and Lead-Time Considerations

Hose pricing can vary with bore, length, order quantity, cover or material options, fittings, packaging, and documentation needs. A hose-only quotation is not directly comparable with a quotation for a crimped assembly that includes fittings and assembly work. Minimum order quantity and production lead time are supplier- and order-specific; they should be confirmed rather than assumed from a catalog listing. For urgent replacement needs, provide the required delivery date and ask the supplier to confirm availability before placing the order.

Supplier Evaluation Checklist

• Are working pressure, temperature limits, and minimum bend radius stated for the selected size?
• Can the supplier review the specified hydraulic fluid, environment, and fitting details?
• Are quotation scope, MOQ, lead time, packaging, and requested documents clearly stated?
• Can changes to dimensions, materials, or fittings be confirmed before production?
