DIN EN 857 2SC is a compact, high-pressure hydraulic hose type reinforced with two braided steel-wire layers. Buyers commonly consider it for machinery and equipment where installation space is limited and the hose must carry hydraulic fluid under pressure. To select it safely, match the hose’s nominal bore, working pressure, temperature range, bend radius, fluid compatibility, and end connections to the actual system requirements. Confirm the current product datasheet and applicable standard edition with your supplier before ordering.
This guide is for hydraulic equipment manufacturers, maintenance teams, distributors, and procurement professionals comparing compact two-wire-braid hose options. It is intended to help buyers understand the main specification points before requesting samples, assemblies, or a commercial quotation. It is not a substitute for system design, the applicable standard, or a manufacturer’s technical documentation. Where a machine or component manufacturer specifies a particular hose, follow that requirement.
DIN EN 857 2SC refers to a compact hydraulic hose type described under the EN 857 standard. Its typical construction consists of an oil-resistant synthetic-rubber inner tube, two braided steel-wire reinforcement layers, and an outer cover intended to protect the reinforcement from the working environment. Exact compounds, dimensions, and performance ratings depend on the product and should be confirmed in its datasheet.
The inner tube carries the hydraulic medium, while the steel-wire braids provide reinforcement against internal pressure. The outer cover helps protect the hose from external exposure, but its resistance to abrasion, weather, oils, and other substances should not be assumed without product-specific information. Fittings and assembly methods also matter: the completed hose assembly must be suitable for the system, not just the hose itself.
The “2SC” designation describes the hose type and reinforcement construction; it is not a universal pressure rating. A hose with a particular nominal bore can have a different working pressure from another size in the same family. Check the manufacturer’s pressure table for the exact diameter, product version, and assembly conditions you plan to use.
Start with the system’s maximum operating pressure, including relevant pressure peaks, then select a hose whose documented working-pressure rating is appropriate for the application. Do not confuse working pressure with burst pressure, and do not use a burst figure as a normal operating limit. As an illustration of the units involved, hydraulic hose pressure ratings are often stated in bar; verify the actual rating for each nominal size in the chosen supplier’s datasheet.
Match the nominal bore to the system’s flow requirements and connection sizes. A bore that is too small can contribute to excessive pressure loss and heat, while an unnecessarily large hose may complicate routing and connection selection. Temperature limits also depend on the hose construction and fluid; request the product’s stated operating range instead of applying a generic range to every 2SC hose.
Check the minimum bend radius published for the exact hose size, and route the hose without forcing it into a tighter curve. For example, a bend-radius value may be specified in millimetres; use the manufacturer’s figure for the selected product rather than relying on a general estimate. Avoid twisting the hose during installation, and allow for movement, vibration, and clearance from sharp edges or hot surfaces.

Confirm compatibility with the hydraulic fluid, expected temperature, and external environment. Hydraulic oils, water-based fluids, cleaning agents, and other media may require different compatibility checks. If the hose will face abrasion, outdoor exposure, or contact with chemicals, ask the supplier for the cover’s relevant product-specific resistance information.
DIN EN 857 2SC hoses are considered in hydraulic circuits where a compact, two-wire-braid construction is appropriate. Potential uses include mobile machinery, industrial equipment, and other hydraulic systems, subject to pressure, temperature, fluid, and installation requirements. The application name alone does not establish suitability; the design conditions and equipment manufacturer’s specifications must agree with the hose rating.
For a moving assembly, assess flexing frequency, vibration, routing, and protection against abrasion. For a fixed installation, focus on pressure, fluid compatibility, bend radius, and connection details. If the application involves unusual fluids, extreme temperatures, or demanding impulse conditions, provide those details to the hose supplier and request written confirmation of suitability.
A frequent error is selecting a hose solely by outside diameter or a familiar product name without confirming nominal bore and pressure. Another is overlooking fluid compatibility or the minimum bend radius, which can lead to an unsuitable choice or difficult installation. Buyers should also avoid treating the hose rating as the rating of the complete assembly unless the fittings, crimping method, and assembly documentation support that conclusion.
Pricing can vary with hose size, requested length, construction details, fitting type, order quantity, packaging, and inspection or documentation requirements. Minimum order quantity and lead time are supplier- and order-specific, so they should be confirmed in the quotation rather than assumed from a catalogue listing. For a more useful quote, send the required size, quantity, hose length, end connections, delivery destination, and any required documentation.
When comparing offers, check that suppliers are quoting the same hose construction and assembly scope. A low initial price may not include fittings, assembly, protective accessories, or the documentation your project needs. Confirm whether the quotation refers to hose by the metre, finished assemblies, or both, and clarify any sample or production-order terms.
As a hose manufacturer and supplier, Hengshui Xinchi Hose Manufacturing Co., Ltd. can discuss DIN EN 857 2SC hose requirements with B2B buyers seeking product and sourcing information. Share the application conditions and assembly specifications so we can assess the requested configuration and confirm available product details. Any performance or compliance requirement should be verified against the documentation for the exact product being quoted.
Choose a DIN EN 857 2SC hydraulic hose by matching its documented pressure, bore, temperature range, fluid compatibility, bend radius, and assembly details to your system—not by relying on the designation alone. The next step is to prepare your operating conditions and fitting requirements, then compare them with the supplier’s datasheet and quotation. For a sourcing discussion, contact Hengshui Xinchi Hose Manufacturing Co., Ltd. with your target size, quantity, application, and delivery requirements to request product information and a quote.
