Your Position: Home - Rubber Products - DIN EN853 2SN vs DIN EN857 2SC Hydraulic Hose
DIN EN853 2SN and DIN EN857 2SC are both high-pressure hydraulic hoses reinforced with two steel-wire braids, but they are not interchangeable by name alone. In general, 2SC is a more compact construction designed to fit tighter routing spaces, while 2SN is the conventional two-wire-braid option for standard hydraulic installations. Their pressure capabilities can be similar at matching nominal sizes, so buyers should compare the exact hose size, working pressure, bend radius, fittings, and operating conditions before ordering. The correct choice is the hose that meets the equipment specification and fits the installation without violating its minimum bend radius.
Both hose types are used to convey hydraulic fluids in mobile and industrial equipment, and both use two layers of steel-wire braid. The main practical distinction is that EN 857 2SC products are typically more compact, with a smaller outside diameter and a tighter minimum bend radius than comparable EN 853 2SN products. These differences can make 2SC easier to route in confined assemblies, while 2SN can suit installations with more available space and an existing 2SN specification.
EN 853 2SN identifies a hydraulic hose type with two steel-wire braid reinforcement layers. It is commonly selected for general high-pressure hydraulic lines where the hose can be routed within its specified bend radius. “2SN” is a hose construction designation, not a complete application approval; buyers still need to verify the hose’s pressure rating, fluid compatibility, temperature range, and assembly details.
EN 857 2SC also uses two steel-wire braid reinforcement layers, but it belongs to a compact hose specification. Compared with a similar-bore 2SN hose, a 2SC product commonly has a smaller outside diameter and a tighter minimum bend radius. Those characteristics can support more compact routing, but they do not automatically make 2SC suitable for every 2SN application or guarantee a higher pressure rating.
The table below summarizes typical differences buyers encounter. Exact values can vary by nominal size, manufacturer, and product construction, so use the selected manufacturer’s technical datasheet and the applicable standard when approving a hose. Pressure figures are working-pressure examples, not a substitute for confirming the complete hose-and-fitting assembly.
| Comparison point | EN 853 2SN | EN 857 2SC |
|---|---|---|
| Reinforcement | Two steel-wire braid layers | Two steel-wire braid layers |
| Typical design emphasis | Standard two-braid hydraulic hose construction | Compact construction and space-efficient routing |
| Outside diameter | Typically larger than a comparable 2SC product | Typically smaller than a comparable 2SN product |
| Bend radius | Typically requires a wider routing curve | Typically allows a tighter curve; confirm the exact datasheet value |
| Pressure capability | Depends on nominal size and product specification | Depends on nominal size and product specification; do not assume it is higher |
For a specific pressure reference, representative product tables commonly list a 6 mm nominal-bore 2SN hose at up to 400 bar working pressure, while a 25 mm nominal-bore 2SN hose may be listed at up to 215 bar. A representative 25 mm 2SC product may be listed at 210 bar. These examples show why size matters: pressure generally changes across the hose range, and even similar hose types can have different ratings at the same bore.
Minimum bend radius is another measurable difference. For example, some product catalogs list a 25 mm 2SN hose with a 300 mm minimum bend radius and a 25 mm 2SC hose with a 150 mm minimum bend radius. Treat these as examples rather than universal guaranteed values, and do not bend a hose below the limit published for the product you buy. The hose assembly, routing, and operating movement should all be considered during design.

2SN can be a practical option for machinery with adequate routing space and a hose specification already written around EN 853 2SN. It may also simplify replacement when the original assembly, fittings, and maintenance documentation identify 2SN. In these cases, verify that the replacement matches the required bore, working pressure, length, end connections, and fluid conditions.
2SC is worth evaluating when hoses must pass through restricted spaces or make tighter turns than a standard hose route permits. Its compact dimensions can help with packaging in mobile equipment and other assemblies where clearance is limited. Before changing from 2SN to 2SC, confirm that the equipment maker allows the alternative and that the full assembly meets pressure and compatibility requirements.
Start with the operating requirements, not a preference for one designation. Record the nominal bore, maximum working pressure, fluid type, operating temperature, hose length, end connections, and the minimum available routing radius. Also consider pressure surges, vibration, abrasion exposure, and whether the hose moves during operation, since these factors can affect service conditions.
A frequent mistake is treating 2SC as a direct upgrade to 2SN because it bends more tightly. A smaller bend radius does not, by itself, establish suitability for a system’s pressure, fluid, temperature, or fitting requirements. Another mistake is comparing pressure ratings without matching the nominal bore, or relying on a generic catalog value instead of the selected product’s datasheet.
Buyers should also avoid replacing a hose based only on outside appearance. A hose may look similar while differing in construction, dimensions, or assembly requirements. When the original specification is unclear, provide the supplier with the hose marking, bore, length, fitting details, equipment model, and known operating conditions so the product can be checked before purchase.
At Hengshui Xinchi Hose Manufacturing Co., Ltd., we support B2B buyers comparing hydraulic hose requirements, including the practical differences between EN 853 2SN and EN 857 2SC. Share your required standard, size, pressure, fluid, temperature, hose length, and fitting details so we can help identify the information needed for a product comparison. We recommend confirming the final selection against the equipment specification and the technical datasheet for the exact hose assembly.
DIN EN853 2SN is generally the standard two-wire-braid choice when its routing dimensions suit the installation, while DIN EN857 2SC is generally the compact option for tighter spaces and smaller bend radii. Neither designation is automatically the safer or higher-pressure choice; the correct answer depends on the exact size, product rating, fittings, and operating conditions. Compare verified datasheets at the same nominal bore, then confirm that the complete assembly fits the equipment requirements. For a quotation or technical comparison, send Hengshui Xinchi Hose Manufacturing Co., Ltd. your hose specification and application details.
