The DIN EN857 2SC hydraulic hose is designed for hydraulic systems requiring high working pressure and compact hose routing. Its two-layer steel wire braid reinforcement provides pressure resistance, while the compact construction makes it suitable for equipment with limited installation space.
Compared with conventional hydraulic hose constructions, the EN 857 2SC design is particularly useful where hose outside diameter and bend radius are important selection factors.
The hose is suitable for specified petroleum-based and compatible water-based hydraulic fluids, with an operating temperature range of -40°C to +100°C.
The main advantage of EN 857 2SC is its combination of compact dimensions, two-wire braid reinforcement, and flexibility for hydraulic equipment installation.
The compact hose construction allows routing through narrow equipment compartments and around hydraulic components where space is limited. This is particularly useful for mobile machinery and compact hydraulic systems.
Two layers of braided steel wire provide reinforcement for high-pressure hydraulic fluid transmission. The hose offers working pressure ratings of 16.5–40 MPa, depending on the selected size.
The inner tube is made of oil-resistant nitrile-butadiene synthetic rubber. The outer cover uses oil- and weather-resistant synthetic rubber to help protect the hose during normal industrial operation.
Available in wrapped and smooth outer cover finishes, the hose can accommodate different installation and handling requirements. The applicable minimum bend radius must be observed during routing to avoid excessive bending.
The Honestflex EN 857 2SC hydraulic hose range includes seven standard sizes from 1/4 inch to 1 inch. Working pressure, outside diameter, and minimum bend radius vary by hose size.

When Should You Choose EN 857 2SC?
EN 857 2SC is a suitable option when hydraulic equipment requires two-wire braid pressure capability with a compact outside diameter.
Compared with EN 857 1SC, the 2SC construction provides a higher pressure class at comparable sizes. Compared with EN 853 2SN, the compact 2SC construction can offer advantages where installation clearance and bend radius are important.
The final selection should be based on the applicable pressure rating, minimum bend radius, hose dimensions, fluid compatibility, and manufacturer specifications rather than the hose standard alone.
Used in suitable hydraulic circuits of excavators, loaders, cranes, and other construction equipment where high-pressure fluid transmission and compact routing are required.
Applicable to hydraulic systems in tractors, harvesting machinery, and forestry equipment, especially where hydraulic lines must be routed around moving components and restricted spaces.
The compact design makes EN 857 2SC an option for hydraulic equipment such as forklifts, lifting platforms, and material handling machinery, subject to pressure and installation requirements.
Used for compatible hydraulic oil lines connecting pumps, valves, cylinders, and other components in industrial machinery and hydraulic power systems.
Correct hose selection and installation are essential for safe hydraulic system operation.
1. Verify the Working Pressure
Choose a hose with a rated working pressure suitable for the maximum system pressure, including relevant pressure surges and operating conditions.
2. Check the Minimum Bend Radius
Review the bend radius specified for the selected hose size. Avoid excessive bending, twisting, or installation that places stress near hose fittings.
3. Confirm Fluid and Temperature Compatibility
Check that the hose inner tube is compatible with the hydraulic fluid and operating temperature. Special fluid formulations may require additional compatibility verification.
4. Match Hose Size and Fittings
Select the correct inside diameter, connection type, and hose assembly configuration. Follow the fitting and crimping manufacturer's approved assembly instructions.
The 2SC designation identifies a compact hydraulic hose construction with two layers of steel wire braid reinforcement under the EN 857 standard. It is intended for hydraulic applications requiring the corresponding pressure ratings and compact dimensions.
For the listed Honestflex product, the maximum working pressure is 40 MPa (400 bar / 5800 PSI) for the 1/4-inch size. Pressure ratings decrease for larger hose diameters, as shown in the technical specification table.
Both use two layers of braided steel wire, but EN 857 2SC is designed with more compact dimensions. This can make it preferable in hydraulic systems with limited routing space. Pressure ratings and bend radius requirements should be compared by size.
The hose is intended for petroleum-based and specified water-based hydraulic fluids. Compatibility depends on the exact fluid formulation, concentration, operating temperature, and application conditions. Confirm the intended fluid before use.
EN 857 2SC is primarily intended for pressure hydraulic lines. It should not be used for vacuum or suction service unless the specific hose assembly has an appropriate verified vacuum rating.
Please provide the hose size, required length, working pressure, fluid type, order quantity, and destination market. If assembled hoses are required, include the fitting types and assembly specifications for confirmation.
