DIN EN 857 2SC Hydraulic Hoses: Specifications, Applications, and Selection Guide

DIN EN 857 2SC is a compact hydraulic hose type designed for pressure lines where flexibility and a relatively small outside diameter are important. It typically has an oil-resistant synthetic rubber tube, two high-tensile steel wire braids, and a protective rubber cover. The standard identifies a hose construction and performance class; the correct working pressure, dimensions, temperature limits, and fittings must still be confirmed for the selected size and product.

In this guide, we explain how to assess 2SC hoses for hydraulic equipment, what information to check before ordering, and when another hose type may be more suitable. At Hengshui Xinchi Hose Manufacturing Co., Ltd., we support B2B buyers by reviewing application requirements and confirming product details before quotation.

Key Takeaways

• 2SC is a two-steel-wire-braid hose construction covered by DIN EN 857.
• Typical temperature limits are approximately -40°C to +100°C for compatible hydraulic fluids, but the chosen product datasheet takes precedence.
• Pressure capacity, bend radius, dimensions, and fitting compatibility depend on hose size and product design.
• Before purchase, match the hose to the fluid, pressure, temperature, routing, and operating environment.

Who This Guide Is For

This guide is intended for hydraulic equipment manufacturers, distributors, maintenance teams, and procurement professionals evaluating compact high-pressure hose assemblies. It is useful when replacing an existing hose, specifying a new machine, or comparing supplier quotations. It is not a substitute for the applicable standard, equipment instructions, or a product-specific technical datasheet.

What Is a DIN EN 857 2SC Hose?

Construction and purpose

DIN EN 857 2SC describes a compact hose category commonly used to convey hydraulic fluids in mobile and industrial systems. Its reinforcement consists of two steel wire braids, which help the hose withstand pressure while retaining flexibility appropriate to its design. The inner tube is generally formulated for hydraulic-fluid compatibility, while the outer cover protects the reinforcement from external exposure.

The “2SC” designation refers to the hose type, not a universal pressure rating for every diameter. Product dimensions and performance requirements vary by nominal bore and manufacturer. Buyers should therefore compare the technical data for the exact size rather than infer performance from the designation alone.

Typical material layers

• Inner tube: Synthetic rubber selected for compatibility with specified hydraulic fluids.
• Reinforcement: Two braids of high-tensile steel wire.
• Outer cover: Rubber compound intended to protect against common environmental and mechanical exposure.

Material compounds and cover options can differ between product ranges. Confirm fluid compatibility, cover properties, and any special requirements with the supplier before selecting a hose.

Specifications Buyers Should Check

Pressure, temperature, and dimensions

Start with the required working pressure, including pressure peaks that may occur during equipment operation. Compare it with the supplier’s rated working pressure for the exact hose size and assembly, and check any applicable test or burst-pressure information in the product documentation. Do not treat a burst rating as an allowable operating pressure.

Many 2SC products are specified for a temperature range around -40°C to +100°C when used with compatible hydraulic fluids. These figures are typical rather than universal: fluid type, duty cycle, ambient conditions, and product construction can affect suitability. Check the manufacturer’s stated limits for both the conveyed fluid and the external environment.

Confirm nominal bore, inside and outside diameter, minimum bend radius, and hose length. Routing a hose below its specified bend radius or twisting it during installation can shorten service life. Also check whether the requested dimensions refer to the hose itself or to the completed assembly, including end fittings.

Fluid and fitting compatibility

Identify the exact fluid, including whether it is mineral-oil-based, biodegradable, water-based, or another formulation. A rubber compound suitable for one fluid may not be suitable for another, so request a compatibility confirmation when the fluid is unfamiliar. Specify the fitting type, thread, sealing method, orientation, and assembly length to avoid connection problems.

Applications and Hose-Type Matching

2SC hoses are commonly considered for hydraulic lines in construction and agricultural machinery, material-handling equipment, machine tools, and industrial power systems. Their compact construction can be useful where installation space is limited or hose routing requires flexibility. Actual suitability depends on the machine’s pressure, temperature, movement, and exposure conditions.

For an exposed installation, assess abrasion, weather, oil contact, and proximity to hot surfaces. For a moving line, consider repeated flexing, vibration, and the hose’s bend radius. Where the system involves unusually high pressure, severe external damage risk, or specialized fluids, compare other hose constructions and protective options rather than assuming 2SC is the best fit.

A Practical Selection Framework

1. Document the operating conditions. Record normal and peak pressure, fluid, temperature, duty cycle, and ambient exposure.
2. Measure the installation. Confirm bore, length, connection details, routing path, and available bend radius.
3. Match the hose specification. Review the product datasheet for the exact diameter, pressure rating, temperature limits, and dimensions.
4. Confirm the complete assembly. Verify fitting materials, end connections, crimping requirements, and orientation with the hose supplier.
5. Review documentation and inspection needs. Request traceability or test documentation where required by your purchasing specification.

Common selection mistakes

A frequent error is choosing by hose designation alone without checking size-specific ratings. Other avoidable issues include overlooking pressure spikes, selecting an incompatible tube compound, and specifying a hose length without accounting for fitting dimensions or machine movement. Installation errors—such as twisting, sharp bends, or contact with abrasive edges—can also compromise performance.

Pricing, MOQ, and Lead-Time Considerations

The price of a 2SC hose or assembly can depend on size, order quantity, requested length, fittings, packaging, and documentation requirements. Custom assemblies may require additional specification review compared with standard hose lengths. Because commercial terms vary by product and order, buyers should request a quotation based on a complete specification rather than comparing unit prices alone.

Minimum order quantities and lead times depend on the requested construction, stock availability, production schedule, and destination. Provide forecast volumes and required delivery dates when requesting pricing. This helps the supplier identify practical options and clarify whether the request involves standard stock or a made-to-order configuration.

Supplier Evaluation Checklist

• Can the supplier provide a datasheet for the exact hose size and construction?
• Are working pressure, temperature range, dimensions, and bend radius stated clearly?
• Can the supplier confirm compatibility with the specified fluid and operating environment?
• Are fitting details, assembly requirements, packaging, and inspection documents addressed?
• Are quotation validity, MOQ, lead time, and shipping terms clear?

At Hengshui Xinchi Hose Manufacturing Co., Ltd., we work with B2B buyers to clarify application conditions and product requirements for hydraulic rubber hoses. Share your required size, working pressure, fluid, temperature range, fitting details, quantity, and delivery destination so we can assess the request and provide relevant product information. Any final selection should be checked against the equipment requirements and confirmed technical documentation.

Conclusion

DIN EN 857 2SC is a compact, two-steel-wire-braid hydraulic hose option for applications that need pressure resistance and practical routing flexibility. It is suitable only when its size-specific pressure rating, temperature limits, fluid compatibility, bend radius, and fittings match the actual system. Before ordering, prepare the operating details and review the exact product datasheet with your supplier; contact Hengshui Xinchi Hose Manufacturing Co., Ltd. with those requirements to discuss a suitable hose or assembly.
