2SN vs 2SC Hydraulic Hose: Bend Radius, Outer Diameter, and Pressure
For buyers comparing 2SN and 2SC hydraulic hose, the main practical difference is usually compactness: 2SC is designed with a smaller outer diameter and a tighter minimum bend radius than a comparable 2SN hose. Their working pressures can be similar at the same nominal bore, so 2SC is not automatically a higher-pressure option. As one illustrative DN10 (3/8-inch) catalog comparison, 2SN may have an outside diameter around 17.4 mm and a minimum bend radius of 130 mm, while 2SC may be around 16 mm and 90 mm; both may be rated near 330 bar. Always confirm the precise hose datasheet and applicable standard before specifying or ordering.
Quick comparison: 2SN and 2SC
Both hose types use two steel wire braid reinforcement layers and are intended for hydraulic service. 2SN is associated with EN 853, while 2SC is associated with EN 857. Although their reinforcement count is alike, their construction and dimensional requirements differ, which affects routing and installation space.
- Bend radius: 2SC commonly allows tighter routing at a comparable nominal bore.
- Outer diameter: 2SC is commonly more compact, but the actual difference depends on size and manufacturer.
- Pressure: Compare the rated working pressure for the exact bore and product; the type name alone does not establish that one has a higher rating.
- Selection: Choose based on the application’s pressure, temperature, fluid, routing, fittings, and relevant standard—not on compactness alone.
What the designations mean
2SN: two-wire-braid hose to EN 853
2SN identifies a hydraulic hose with two steel wire braid reinforcement layers, commonly specified to EN 853. It is widely considered where a conventional two-braid hose design meets the equipment’s pressure and routing requirements. Its outside diameter and minimum bend radius are determined by nominal bore and product construction, so buyers should use the selected manufacturer’s dimension table rather than rely on a general rule.
2SC: compact two-wire-braid hose to EN 857
2SC also has two wire braid reinforcement layers, but it is a compact hose type associated with EN 857. Its dimensions can help in installations with limited clearance or tighter routing, including some mobile machinery and compact hydraulic assemblies. The compact design does not remove the need to check pressure, temperature, fluid compatibility, and assembly requirements for the actual product.
Comparison of bend radius, outer diameter, and pressure
| Comparison point | 2SN | 2SC | What buyers should verify |
|---|---|---|---|
| Associated standard | EN 853 | EN 857 | Specified standard and product datasheet |
| Reinforcement | Two steel wire braid layers | Two steel wire braid layers | Construction details and product identification |
| Bend radius | Often larger for a comparable bore | Often smaller for a comparable bore | Minimum bend radius at the selected nominal bore |
| Outer diameter | Often larger for a comparable bore | Often smaller for a comparable bore | Actual outside diameter and clamp or routing clearance |
| Working pressure | Varies by bore and product | Varies by bore and product | Rated working pressure, not just the hose type |
How to interpret example dimensions
For a representative DN10 (3/8-inch) comparison, a product datasheet might list 2SN at approximately 17.4 mm outside diameter with a 130 mm minimum bend radius, and 2SC at approximately 16 mm outside diameter with a 90 mm minimum bend radius. These figures are illustrative product values, not universal dimensions for every hose carrying the same designation. Even a modest diameter difference can matter where clamps, guards, or neighboring lines restrict available space.
Pressure is size- and product-specific
A comparable DN10 product may list a working pressure of about 330 bar for either hose type, but this example should not be applied to every size or supplier. Pressure ratings generally change with nominal bore and must be checked against the manufacturer’s stated value. Also distinguish working pressure from burst pressure: burst pressure is not a permissible operating target.

Which hose suits your application?
Choose 2SC when installation space is the constraint
2SC is worth evaluating when a machine layout requires a smaller hose envelope or a tighter bend than the available 2SN option can provide. A more compact hose can simplify routing in some assemblies, but only if its pressure and environmental ratings match the duty. Confirm that the planned path respects the minimum bend radius, including near the fittings where bending stress can be concentrated.
Choose 2SN when it meets the design requirements
2SN can be a suitable choice when its specified pressure, dimensions, and bend radius fit the equipment, and a compact hose is not needed. Existing equipment designs, replacement specifications, or assembly conventions may also call for 2SN. Do not substitute 2SC or 2SN solely because the hose appears similar: verify the specified standard, bore, fittings, and service conditions first.
Buyer selection checklist
- Confirm nominal bore. Match the hose size to the required flow and connection specification.
- Check operating conditions. Record working pressure, temperature range, hydraulic fluid, and any pressure surges or demanding duty cycles.
- Measure the installation. Check available clearance, actual route length, clamp spacing, and the tightest bend in the assembly.
- Compare datasheets. Review the selected product’s outside diameter, minimum bend radius, pressure rating, and applicable standard.
- Confirm the assembly. Check fitting compatibility and follow the hose and fitting manufacturer’s assembly instructions.
One frequent sourcing mistake is comparing 2SN and 2SC by nominal bore alone. Products with the same bore can still differ in dimensions and ratings between manufacturers, so a drawing or approved datasheet is important for equipment replacements. Another mistake is forcing a hose below its minimum bend radius to make a compact design fit; revise the route or select a suitable product instead.
Ordering and supplier coordination
When requesting a quotation, send the hose type, nominal bore, required length, working pressure, temperature and fluid conditions, fitting details, and destination market. Include the installation’s minimum clearance or bend requirement if compactness is important. This information helps suppliers assess whether the requested specification is complete and identify details that need confirmation before production or assembly.
At Hengshui Xinchi Hose Manufacturing Co., Ltd., we support B2B buyers evaluating rubber hydraulic hose requirements, including the comparison of 2SN and 2SC specifications. Share your application details and target dimensions so our team can discuss suitable product options and the information needed for a quotation. Final selection should always be based on the confirmed product datasheet and the requirements of the hydraulic system.
Conclusion: how to decide between 2SN and 2SC
For comparable bores, 2SC is generally the more compact option, with a tighter bend radius and smaller outside diameter; 2SN may fit where its dimensions and routing requirements are acceptable. Neither designation alone guarantees a higher working pressure, so compare the rated pressure for the exact size and product. Start by checking clearance and bend radius, then confirm pressure, fluid and temperature compatibility, fittings, and the applicable standard. If you are sourcing for a project or replacement, send your operating conditions and dimensional requirements to Hengshui Xinchi Hose Manufacturing Co., Ltd. for a specification discussion.
