DIN EN 853 2SN Hydraulic Hoses: Specifications and Selection Guide
DIN EN 853 2SN is a high-pressure hydraulic hose type with an oil-resistant inner tube, two braided steel-wire reinforcement layers, and a protective outer cover. Buyers typically consider it for hydraulic systems that need a flexible hose assembly, but the correct choice depends on bore size, operating pressure, fluid, temperature, routing, and end connections. The standard defines hose requirements; it does not mean every 2SN hose has the same pressure rating or is suitable for every hydraulic fluid. Confirm the selected product’s technical data and the completed assembly’s requirements before ordering.

Key Takeaways
- 2SN describes a two-wire-braid construction; pressure capacity depends on the hose size and manufacturer’s specification.
- Commonly stated temperature limits are approximately -40°C to +100°C for petroleum-based hydraulic fluids, with lower limits for some water-based fluids.
- Check working pressure, fluid compatibility, temperature, bend radius, routing, and fitting compatibility as one selection process.
- For a quotation, provide the hose size, operating conditions, required length, end fittings, and expected order quantity.
Who This Guide Is For
This guide is intended for hydraulic equipment manufacturers, maintenance teams, distributors, and industrial procurement professionals evaluating 2SN hose. It is useful when specifying a replacement hose, developing a bill of materials, or comparing supplier quotations. It is not a substitute for the equipment manufacturer’s instructions or a product-specific technical datasheet. Where a system has unusual pressure peaks, fluid, or environmental conditions, request technical review before purchase.
What DIN EN 853 2SN Means
Construction and Function
The “2SN” designation identifies a hose construction using two braids of high-tensile steel wire. The inner tube is designed for contact with compatible hydraulic fluid, while the outer cover protects the reinforcement from external exposure and handling. The wire reinforcement helps the hose contain hydraulic pressure, and the flexible construction allows it to be routed through machinery. The complete hose assembly also depends on correctly matched fittings and professional assembly.
Typical Temperature Guidance
For petroleum-based hydraulic fluids, 2SN products are commonly specified for a service temperature range of about -40°C to +100°C. For water-based fluids, the allowable upper temperature is often lower; a commonly referenced limit is +70°C. These are general selection reference points, not a guarantee for every fluid, hose formulation, or assembly. Always check the supplier’s datasheet for the actual product and confirm that both the fluid and ambient temperatures remain within its stated limits.
Specifications to Confirm
Do not select a hose by its 2SN label alone. The following details should be checked against the application and the supplier’s documentation.
| Specification | Why It Matters | What to Confirm |
|---|---|---|
| Nominal bore and inner diameter | Influences flow capacity and hose routing. | Match the equipment requirement and connection size. |
| Working pressure | Must accommodate the system’s operating conditions. | Check the rating for the selected bore and product. |
| Fluid compatibility | Fluid can affect the inner tube and service life. | Identify the fluid type and any additives. |
| Temperature range | Both fluid and surrounding temperatures matter. | Compare actual conditions with product limits. |
| Fittings and assembly | A hose is only useful when connections suit the system. | Specify fitting type, thread, material, and assembly needs. |
Applications and Product Matching
2SN hoses are used in hydraulic circuits on industrial equipment, construction machinery, agricultural machinery, and other systems where the specified hose performance fits the duty. Typical functions include conveying pressurized hydraulic fluid between components such as pumps, valves, and cylinders. Actual suitability depends on system pressure, movement, exposure, fluid, and installation conditions—not simply on the machine category. Follow the equipment maker’s requirements where they specify a hose type or assembly.
Choose by Operating Conditions
Start with the machine’s maximum operating pressure and consider pressure fluctuations or peaks described by the equipment manufacturer. Compare that requirement with the hose’s stated working pressure for the exact size, and do not use burst pressure as an operating target. Next, verify fluid and temperature compatibility, including exposure to heat, cold, abrasion, weather, or other environmental factors. If the hose moves during operation, account for movement and routing when confirming length and bend radius.

Size and Routing
A bore that is too small can increase fluid velocity and pressure loss, while a bore that is too large may not match the system’s connections or design. Use the equipment specification or existing assembly details to establish nominal size, then verify actual dimensions and fitting interfaces with the supplier. Check the minimum bend radius in the product datasheet and avoid sharp bends, twisting, or tension at the connection points. Where routing is constrained, share a drawing or clear photographs with the supplier before confirming the order.
A Practical Selection Framework
- Document the duty: Record the fluid, normal and maximum operating pressure, temperature range, and operating environment.
- Identify the size: Confirm nominal bore, required length, and connection dimensions from equipment documents or the existing assembly.
- Check the specification: Match the 2SN product’s stated working pressure, temperature range, bend radius, and fluid compatibility to the application.
- Specify the assembly: State fitting type, thread or connection standard, orientation, and any protective sleeve or cover requirements.
- Review the supplier offer: Compare the offered datasheet and quotation with your requirements before approving production or shipment.
Common Selection Mistakes
A frequent mistake is treating all hoses marked 2SN as identical across sizes and suppliers. Another is choosing by outside appearance while overlooking bore, working pressure, fitting details, or the fluid being conveyed. Buyers may also overlook installation conditions, such as a bend that is tighter than the manufacturer permits or a route that causes abrasion. Ask for clarification whenever a quotation does not identify the hose size, pressure data, or end connections clearly.
Pricing, MOQ, and Lead Time
The purchase price can vary with hose bore, order length, fitting type, assembly requirements, and any requested packaging or documentation. Minimum order quantities and production lead times also depend on the selected configuration and the supplier’s current production schedule. Because these details cannot be reliably inferred from the 2SN designation, request a project-specific quotation rather than relying on a generic price. For a more useful offer, include estimated quantity, delivery destination, target schedule, and whether you need bulk hose or finished assemblies.
Supplier Evaluation Checklist
Before placing an order, check that the supplier can identify the product construction and provide size-specific technical information. Ask whether the quotation clearly states hose size, working pressure, temperature guidance, and the fitting configuration, if applicable. Confirm how the supplier handles product identification, packaging, and shipment documentation for your order. For a new application, share your operating conditions and request a review of the proposed specification instead of assuming that a general product description proves suitability.
