EN 857 2SC is often a better choice than EN 853 2SN when a hydraulic line must pass through tight spaces, make shorter-radius turns, or fit into a compact machine layout. Both hose types use two steel wire braids, but 2SC is designed as a compact construction and commonly has a smaller minimum bend radius. For example, published product tables may show a minimum bend radius of 50 mm for DN6 2SC, compared with 100 mm for DN6 2SN; confirm the figures for the exact hose and supplier before designing the route. At Hengshui Xinchi Hose Manufacturing Co., Ltd., we recommend choosing by verified hose specifications, operating conditions, and compatible fittings—not by the “compact” label alone.
EN 857 2SC and EN 853 2SN are hydraulic hose types defined by different European hose standards. Both are commonly specified with two steel wire braid reinforcement layers, but their constructions and dimensional requirements differ. The “2SC” designation is associated with a compact hose construction, while 2SN is a familiar two-wire-braid hose type under EN 853. The designation alone does not establish whether a particular hose is suitable for a machine; the manufacturer’s technical data and the equipment requirements still apply.
When comparing products, use the same nominal bore and check the actual specification sheets side by side. Depending on the model and size, outside diameter, minimum bend radius, working pressure, and other limits may vary. Avoid treating one size’s figures as representative of every diameter in a product range.
The most relevant difference for a crowded hose route is often the minimum bend radius. A smaller permitted radius can give a designer more flexibility around valves, manifolds, cylinders, and machine frames. As one illustrative comparison, product data may list a 50 mm minimum bend radius for DN6 2SC and 100 mm for DN6 2SN. These are product-table examples, not a substitute for checking the data sheet for the specific hose being purchased.
Do not interpret a minimum bend radius as a recommended target for every installation. The routing design should respect the supplier’s stated limit, avoid sharp kinks, and allow for movement where the hose connects to moving equipment. If the line must flex repeatedly, the movement pattern and hose length also need review.
In a confined assembly, outside diameter matters alongside bend radius. A smaller hose envelope may help with routing through a narrow channel or keeping adjacent lines separated, but the exact difference depends on the hose size and product construction. We advise buyers to compare the listed outside diameter for the selected DN rather than assuming every 2SC product is smaller than every 2SN product.
Space planning should include more than the hose itself. Fittings, ferrules, clamps, and the straight section required near a connection can influence whether the completed assembly fits. A route that appears feasible on a hose-only drawing may still interfere with nearby components once the end connections are installed.
2SC may be worth evaluating for compact hydraulic power units, mobile machinery, machine tools, and other equipment where lines pass through limited space. It can also be relevant when designers are revising an existing route to reduce congestion. These are potential applications rather than guarantees of suitability; pressure, temperature, fluid, vibration, and operating movement must still match the selected hose assembly.
| Selection point | EN 857 2SC | EN 853 2SN |
|---|---|---|
| Reinforcement | Commonly specified with two steel wire braids | Commonly specified with two steel wire braids |
| Routing priority | Often considered when compact routing and a smaller bend radius are important | Can suit routes with enough space to meet its specified dimensions and bend radius |
| Product dimensions | Check the exact model’s outside diameter and minimum bend radius | Check the exact model’s outside diameter and minimum bend radius |
| System suitability | Verify pressure, temperature, fluid, fittings, and applicable requirements | Verify pressure, temperature, fluid, fittings, and applicable requirements |
A compact hose is not automatically the right hose for every hydraulic circuit. If the existing design specifies 2SN, replacing it with 2SC without engineering approval may create compatibility or compliance concerns. The working pressure must be suitable at the actual operating temperature, and the hose must be compatible with the hydraulic fluid and environment.

Fitting compatibility also deserves attention. Hose types can require specific fittings and assembly procedures, so a hose should not be paired with an end connection solely because the nominal bore appears to match. Confirm the approved hose-and-fitting combination with the component supplier and follow the relevant assembly instructions.
Also consider installation and service conditions. A tight route that reaches the stated minimum bend radius may leave little allowance for equipment movement, maintenance access, or assembly variation. If the hose will flex during operation, evaluate that motion rather than relying only on a static routing drawing.
Record the required nominal bore, maximum working pressure, temperature range, fluid type, and any applicable equipment or project specification. Use the pressure rating for the exact hose size and product, and account for the operating conditions stated by the manufacturer. If any requirement is uncertain, resolve it before selecting a hose type.
Measure clearances in millimetres and identify the tightest turn, nearby components, clamp positions, and movement points. Compare these measurements with the product’s minimum bend radius and outside diameter, then include the dimensions of the proposed fittings. This step helps establish whether 2SC’s compact construction provides a practical benefit over 2SN in the actual installation.
Confirm that the hose, fittings, ferrules, and assembly method are suitable as a combination. Check the required hose length and orientation as well, especially where angled fittings or moving connections are involved. For replacements, match the equipment specification and consult the responsible engineer when changing from one hose type to another.
At Hengshui Xinchi Hose Manufacturing Co., Ltd., we support buyers evaluating hydraulic hose options by discussing the required type, size, operating conditions, and assembly details. We can help clarify which product information is needed to assess a 2SC or 2SN request, including dimensions and application requirements. The final selection should be based on the technical data for the offered product and the buyer’s equipment specification.
To make an inquiry useful, share the required standard, nominal bore, working pressure, temperature range, fluid, hose length, fitting details, and expected quantity. If you are comparing 2SC with an existing 2SN assembly, include the current markings or specification where available. This allows our team to review the request more accurately and identify information that may need confirmation before quotation.
EN 857 2SC often fits compact hydraulic routing better than EN 853 2SN because its compact construction can provide a smaller specified bend radius and, depending on the product, a useful dimensional advantage. The difference should be verified for the exact hose size and manufacturer rather than assumed from the designation. 2SN remains appropriate when the route, equipment specification, and product data support it.
Before placing an order, compare the data sheets, measure the installation, and confirm the complete hose-and-fitting assembly against system requirements. Send Hengshui Xinchi Hose Manufacturing Co., Ltd. your application details and target specification to discuss a suitable product option for your hydraulic project.
