DIN EN853 2SN vs DIN EN857 2SC Hydraulic Hose: Differences and Selection Guide
DIN EN853 2SN and DIN EN857 2SC are both two-wire-braid hydraulic hoses, but they are not identical. The key difference is that EN857 2SC is a compact hose design, generally selected where installation space is limited or a tighter bend is needed; EN853 2SN is the conventional two-braid option. Neither designation alone tells you which hose has the higher working pressure for a particular size, so compare the pressure rating, bend radius, dimensions, fluid compatibility, and temperature range on the supplier’s datasheet before specifying or substituting a hose.

Key Takeaways
- Both hose types use two high-tensile steel wire braid reinforcement layers.
- EN857 2SC is designed as a compact hose and commonly offers a smaller outside diameter and tighter minimum bend radius than a comparable EN853 2SN size.
- Working pressure and physical dimensions depend on nominal bore and manufacturer specifications; do not assume they are identical between products.
- Choose based on the system’s pressure, routing space, fluid, temperature, fittings, and applicable standard—not on the hose name alone.
What Do EN853 2SN and EN857 2SC Mean?
EN853 2SN: Conventional two-wire-braid hose
EN853 2SN is a hydraulic hose construction with an oil-resistant synthetic-rubber tube, two braided steel-wire reinforcement layers, and a protective rubber cover. The reinforcement is designed to contain hydraulic pressure within the hose’s rated operating limits. The “2” identifies the two-wire-braid construction, while “SN” identifies the hose type within the EN853 standard.
Buyers commonly consider 2SN for general hydraulic circuits on mobile and industrial equipment. It can be a suitable choice when the installation has enough space for its outside diameter and bend radius, and the product’s ratings match the system requirements. The standard designation does not replace a product-specific datasheet: verify pressure, dimensions, and operating conditions for the exact size being purchased.
EN857 2SC: Compact two-wire-braid hose
EN857 2SC also has two steel-wire braid reinforcement layers, but it is a compact design. Compared with a similar nominal bore of conventional 2SN hose, a 2SC product commonly has a smaller outside diameter and a tighter minimum bend radius. These characteristics can make routing easier in confined machinery or assemblies with limited clearance.
Compact construction does not mean that every 2SC hose is automatically a better or higher-performance replacement. Its pressure rating, bend radius, and dimensions still depend on the hose size and the manufacturer’s specification. Check that the hose, fittings, and assembly all meet the application’s operating and installation requirements.
EN853 2SN vs EN857 2SC: Feature Comparison
| Comparison point | DIN EN853 2SN | DIN EN857 2SC |
|---|---|---|
| Reinforcement | Two braided steel-wire layers | Two braided steel-wire layers |
| Design focus | Conventional two-braid construction | Compact two-braid construction |
| Installation space | Check the product’s outside diameter and routing clearance | Often advantageous where space is restricted |
| Bend radius | Confirm the minimum value for the selected size | Commonly tighter than comparable 2SN products; verify the datasheet |
| Pressure rating | Varies by size and product | Varies by size and product; do not infer equivalence from the construction |
| Typical selection driver | Standard routing with adequate clearance | Compact routing or reduced bending space |
Pressure, Temperature, and Dimensional Checks
Both types are commonly specified for hydraulic service within a temperature range of approximately -40°C to +100°C, but the permitted range depends on the hose, fluid, and operating conditions. Treat these figures as typical selection guidance, not a substitute for the exact product datasheet. If the system operates near either temperature limit, confirm the manufacturer’s rating and consider how fluid temperature and ambient conditions affect the assembly.
Pressure ratings change with nominal bore and product construction, so there is no single working-pressure figure that applies to every 2SN or 2SC hose. Check the stated working pressure in MPa or bar, and ensure the system’s maximum operating pressure—including pressure surges—does not exceed the hose assembly’s rating. Also confirm the assembly’s pressure rating, since the fittings and crimping specification are part of the finished product.

For installation, compare the minimum bend radius in millimeters and the hose outside diameter in millimeters for the exact nominal bore. A hose bent below its specified minimum radius may be damaged or have its service life reduced. Measure the actual routing path and account for movement, vibration, and clearance at fittings rather than choosing solely by nominal bore.
Which Hose Suits Your Application?
Consider EN853 2SN when
- The route has sufficient space for the selected hose’s outside diameter and bend radius.
- Your existing design specifies 2SN and the replacement matches its bore, pressure, fittings, and operating conditions.
- You are sourcing a conventional two-wire-braid hose for a hydraulic circuit and have confirmed the product-specific ratings.
Consider EN857 2SC when
- The installation has restricted clearance or requires more compact routing.
- A tighter bend radius could simplify the hose layout without violating the specified minimum radius.
- You have verified that the 2SC product’s pressure rating, dimensions, fittings, and fluid compatibility meet the application requirements.
Neither option is universally superior. A compact 2SC can help address routing constraints, while 2SN may be appropriate where conventional dimensions fit and the existing design calls for that type. In both cases, the decisive comparison is between complete product specifications for the required size and operating conditions.
Buyer Selection Checklist
- Confirm the nominal bore: Match the required internal diameter and connection sizes to the equipment specification.
- Verify pressure: Check the hose and assembled-hose working pressure against maximum system pressure and foreseeable surges.
- Check routing dimensions: Compare outside diameter and minimum bend radius in millimeters with the available installation space.
- Confirm service conditions: Specify hydraulic fluid, continuous and intermittent temperatures, and relevant environmental exposure.
- Review fittings and assembly details: Confirm end connections, orientation, length, and assembly requirements before ordering.
- Request traceable product information: Ask the supplier for the applicable standard designation and datasheet for the exact hose size and construction.
Common Mistakes to Avoid
A frequent mistake is treating 2SN and 2SC as interchangeable because both have two wire-braid layers. The compact designation may affect outside diameter and bend radius, while pressure ratings and dimensions can differ by size and product. Another risk is selecting a hose using only its nominal bore or a general temperature range, without checking the fluid, fittings, and finished assembly.
Do not force a hose into a route tighter than its specified minimum bend radius or use a hose that rubs against surrounding components. Avoid making substitutions based only on a matching standard label; compare all critical datasheet values and confirm compatibility with the equipment manufacturer’s requirements. When in doubt, provide the supplier with the operating pressure, fluid, temperature, hose length, connections, and installation measurements.
How XINCHI Can Support Your Sourcing
At XINCHI, we support B2B buyers comparing rubber products and hydraulic hose requirements by reviewing the application details that affect hose selection. Share the required EN type, nominal bore, working pressure, fluid, temperature range, hose length, fittings, and routing constraints so we can help identify a suitable specification for quotation. We recommend confirming the final selection against the relevant product datasheet and equipment requirements before production or installation.
Conclusion: Which One Should You Choose?
Choose DIN EN857 2SC when its compact dimensions or tighter specified bend radius solve a real installation constraint and its product ratings meet your requirements. Choose DIN EN853 2SN when its conventional construction fits the routing and the exact size is suitable for the system. Before ordering either hose, compare product-specific working pressure, minimum bend radius, outside diameter, temperature range, fluid compatibility, and fittings.
Your next step is to prepare the system’s operating details and request a datasheet for the exact size and assembly you need. If you send XINCHI those specifications, we can help review the requirements and discuss a suitable sourcing option for your project.
