DIN EN 853 2SN Hydraulic Hoses: Specifications, Applications, and Selection Guide

DIN EN 853 2SN is a two-wire-braid hydraulic hose type for conveying hydraulic fluids in mobile and industrial equipment. Its typical construction combines an oil-resistant synthetic-rubber inner tube, two layers of high-tensile steel-wire reinforcement, and a protective synthetic-rubber cover. To select the right hose, confirm the required nominal bore, working pressure, fluid compatibility, temperature range, bend radius, and end connections against the supplier’s current product data sheet.

This guide is intended for hydraulic equipment manufacturers, distributors, maintenance teams, and industrial buyers evaluating 2SN hoses for a new project or replacement. We explain the construction and main specifications, outline suitable applications, and provide a practical purchasing checklist. Hengshui Xinchi Hose Manufacturing Co., Ltd. supplies hydraulic rubber hoses and can discuss product requirements with buyers seeking a suitable specification.

Key Takeaways

• 2SN identifies a hose construction with two steel-wire braid reinforcement layers; it does not specify one universal pressure rating for every hose size.
• DIN EN 853 2SN products are available across a range of nominal bore sizes, commonly from DN 5 to DN 51, subject to the manufacturer’s product range.
• Check the exact pressure, temperature, bend radius, fluid compatibility, and fitting details on the product data sheet before ordering.
• Share the operating conditions and assembly requirements with your supplier to reduce the risk of selecting an unsuitable hose.

Who This Guide Is For

This guide supports B2B buyers who need to specify or source a high-pressure hydraulic hose for machinery, vehicles, or industrial equipment. It is useful when comparing hose data sheets, preparing a request for quotation, or replacing an existing assembly. It is not a substitute for the equipment manufacturer’s requirements or the hose supplier’s technical documentation.

What Is a DIN EN 853 2SN Hydraulic Hose?

DIN EN 853 is a hose specification covering rubber hoses with wire-braid reinforcement for hydraulic applications. In the designation 2SN, “2” indicates two wire-braid reinforcement layers, while “SN” refers to the hose type in the standard’s naming system. Buyers should verify the applicable edition and the product’s stated conformity with their supplier rather than relying on the designation alone.

Typical Construction and Function

The inner tube is designed for contact with specified hydraulic fluids, while the braided steel reinforcement provides strength to contain pressurized fluid. The outer cover helps protect the hose from its working environment, including abrasion and exposure to weather, depending on the particular compound and product design. Materials and performance can vary between manufacturers, so confirm compatibility with the fluid, ambient conditions, and installation environment.

A common operating temperature range shown for many 2SN products is approximately -40°C to +100°C. This is a reference point, not a guaranteed rating for every fluid or hose assembly; temperature limits may depend on the hydraulic medium, exposure conditions, and manufacturer’s specifications. Use the supplier’s data sheet to confirm the allowable range for your application.

Key Specifications to Check

There is no single working-pressure value for all DIN EN 853 2SN hoses. Allowable pressure depends on nominal bore and the specific product design, so the number printed on a general product description should not replace the size-specific rating. The following items should be checked together before a hose is approved for purchase.

Common product ranges include nominal bores from DN 5 to DN 51, but the sizes available depend on the manufacturer. Do not assume that every size has the same pressure rating or minimum bend radius. Request the relevant data for the exact bore and hose model being quoted.

Applications and Suitability

2SN hoses are used in hydraulic circuits where a two-wire-braid construction is specified and the hose’s pressure and environmental ratings match the equipment. Potential applications include construction and agricultural machinery, material-handling equipment, industrial hydraulic systems, and vehicle hydraulic circuits. Suitability depends on the equipment design and operating conditions, not just the hose designation.

Match the Hose to the Working Conditions

Before choosing 2SN, identify the normal and peak system pressure, fluid type, temperature range, routing, and exposure to abrasion or weather. Consider whether the hose will experience frequent movement, vibration, or tight bends, and confirm that the selected product and assembly can accommodate those conditions. If the equipment specifies a different hose type or a special cover, follow that requirement or obtain engineering approval before substituting.

For outdoor or abrasive environments, discuss cover options and protective measures with the supplier. In confined routing, compare the installation space with the manufacturer’s minimum bend radius and the fittings’ dimensions. Where the hose is exposed to unusual chemicals, extreme heat, or demanding movement, request a specific compatibility review rather than assuming standard materials will be suitable.

Selection Framework for Buyers

1. Record the equipment requirement. Note the hose type, nominal bore, pressure rating, fluid, temperature, and any manufacturer or drawing reference.
2. Measure the assembly. Confirm overall length, fitting styles, thread or connection details, and orientation where applicable.
3. Check installation conditions. Review bend radius, movement, vibration, abrasion, and exposure to weather or other environmental factors.
4. Compare product documentation. Verify that the supplier’s data sheet covers the selected size and confirms the required operating conditions.
5. Confirm the order details. Agree on hose specification, fitting configuration, quantity, packaging, inspection documents, and delivery expectations before placing the order.

Common Selection Mistakes

A frequent mistake is choosing a hose by outside diameter or visual similarity while overlooking the required bore and pressure rating. Another is treating a general temperature range as applicable to every hydraulic fluid and operating condition. Buyers should also avoid substituting a different hose type based only on a similar description, since construction and ratings may differ.

Installation errors can undermine an otherwise suitable selection. A hose routed below its minimum bend radius, twisted during assembly, or placed where it rubs against a machine surface may be exposed to avoidable stress. Follow the hose and equipment manufacturers’ installation instructions, and confirm the assembly orientation before production.

Pricing, MOQ, and Lead-Time Considerations

Pricing is usually affected by hose size, requested length, order quantity, fittings, assembly requirements, packaging, and any documentation requested. Minimum order quantities and lead times are supplier- and order-specific; they can also vary with product availability and customization. Because these details are not fixed by the 2SN designation, request a quotation based on a complete specification rather than comparing a price per metre without context.

For an accurate quotation, provide the hose type, bore, length, quantity, working conditions, fitting details, delivery destination, and any required inspection or documentation. If you are sourcing hose only rather than completed assemblies, state this clearly. Early confirmation of specifications can help buyers compare like-for-like offers and identify missing details before order approval.

Supplier Evaluation Checklist

When comparing suppliers, ask for a current product data sheet showing the ratings for your selected size. Confirm the supplier can explain material compatibility, available sizes, fittings or assembly options, packaging, and order terms. For project-critical applications, agree in advance on the inspection documents and acceptance criteria required for the purchase.

Hengshui Xinchi Hose Manufacturing Co., Ltd. focuses on rubber hose products, including hydraulic hose offerings. Buyers can share drawings, specifications, or operating details to discuss product availability and suitable configurations. Any final selection should be confirmed against the company’s current product documentation and the requirements of the intended equipment.

Conclusion: How to Choose the Right 2SN Hose

DIN EN 853 2SN is a two-steel-wire-braid hydraulic hose type used where its product-specific ratings and construction meet the application requirements. The designation alone does not establish the correct pressure, temperature, fluid compatibility, or fitting configuration for your system. The most reliable next step is to match the hose data sheet to the equipment specification and installation conditions.

Before requesting a quotation, prepare the bore, length, pressure, fluid, temperature, routing details, and connection requirements. Ask your supplier to confirm the exact size-specific ratings, availability, order quantity, lead time, and requested documentation.
