EN 853 2SN Hydraulic Hose

Product Overview

The EN 853 2SN hydraulic hose is an industry-standard, two high tensile steel wire braided reinforced rubber hose designed for high-pressure hydraulic applications. As a critical component in fluid power systems, this hose conforms to the stringent requirements of the ISO/DIN/EN 853 2SN standard, making it a globally recognized and interchangeable product for transmitting petroleum and water-based hydraulic fluids. Its definition in the industry is a medium-pressure hose with excellent impulse performance, constructed from three distinct layers: a synthetic rubber tube, a two-wire braid reinforcement, and a synthetic rubber cover.

What sets this high pressure hose apart is its exceptional balance of strength and flexibility. The inner tube is formulated from a high-quality synthetic rubber blend, delivering outstanding resistance to abrasion, corrosion, and the degrading effects of hydraulic oils. This is reinforced by two layers of high tensile steel wires, which provide the robust strength necessary to handle demanding pressure peaks and surges in hydraulic systems. The outer cover is engineered to withstand harsh environments, offering resistance to abrasion, weather, cuts, aging, and sunlight, ensuring long-lasting service life even outdoors.

This rubber hose solves the critical industry pain points of equipment downtime and frequent hose failure. By providing a consistent working pressure of up to 41.5 MPa (6020 Psi) and a broad working temperature range of -40°C to +100°C, it ensures reliable operation in extreme conditions, from freezing climates to high-heat industrial settings. Whether you are looking for an OEM ODM partner for custom lengths or a bulk supply agreement, this hose is designed to keep your machinery running. We are a leading China based manufacturer and factory, providing comprehensive support and technical solutions for all your hydraulic needs.

Detailed Technical Specifications Table

Structure and Materials

• Tube (Inner Layer): Made from a high-quality, oil-resistant synthetic rubber blend. This layer ensures the purity of the hydraulic fluid, minimizes flow resistance, and provides a robust barrier against corrosion and the abrasive effects of media moving at high speeds.

• Reinforcement (Middle Layer): Comprises two layers of high tensile steel wire braided at precise angles. This optimized braid pattern balances radial and axial strength, providing the structural integrity to withstand high pressure and impulse fatigue, distinguishing it from lower-pressure wire spiral hose designs.

• Cover (Outer Layer): A super high-quality synthetic rubber, specifically formulated for abrasion, weather, cut, aging, sunlight, and ozone resistance. This protective layer ensures the reinforcement remains undamaged even in harsh outdoor environments like forests, coastlines, and factories.

Application Industries

The din en 853 2sn hydraulic hose is the preferred choice for a wide range of mobile and industrial applications.

• Construction & Engineering Machinery: Excavators, loaders, cranes, and concrete pump trucks rely on this hose for their critical hydraulic functions, from boom articulation to tool operation.

• Agricultural & Forestry Equipment: Tractors, combine harvesters, and wood harvesters benefit from its flexibility and resistance to the elements, ensuring productivity in the field.

• Industrial Manufacturing: Heavy injection molding machines, presses, and machine tools use this hose to transmit power reliably in high-cycle, high-pressure environments.

• Mining Equipment: Drilling rigs, crushers, and roof support systems in mines depend on the hose’s robust construction to withstand abrasive dust and high-pressure demands.

• Marine & Offshore Applications: Deck machinery and steering systems utilize this hose for its weather and corrosion resistance in saltwater environments.

Precise Selection Professional Guide

The Complete Hose Assembly Solution
A hose is only as good as the fittings it connects with. We provide a complete hose assembly service to ensure maximum reliability. Our experts can match the EN 853 2SN with the correct crimped fittings, reusable fittings, adapters, and flanges for your specific system, whether it requires BSP, NPT, or JIC connections. By using factory-controlled crimping processes, our pre-made assemblies guarantee a leak-free connection and optimal performance, eliminating the risk of field assembly errors.

EN 853 2SN vs. Other Hydraulic Hoses
Choosing the right hose is critical. The en 853 2sn is often compared to its single-wire counterpart (1SN) and more robust wire spiral hose (like 4SP or 4SH). While 1SN is for lower-pressure return lines, 2sn-en 853 serves medium-to-high pressure systems. For extreme pressure applications with severe shock loads, a wire spiral hose like EN 856 4SP is recommended. Our team can help you navigate these comparisons based on your system’s specification and provide the exact solution you need.

Industry Pain Point Solutions

• For Excavator Boom Arm Failure: The high impulse resistance and pressure capabilities of the en 853 2sn hydraulic hose directly address the extreme pressure spikes in a digger’s arm, dramatically reducing the risk of frequent blowouts.

• For Cold Weather Operations: With a working temperature rated down to -40°C, this rubber hose maintains its flexibility and does not become brittle, ensuring reliable startup and operation in arctic conditions without hose failure.

• For High-Abrasion Environments: In mining or quarry applications, the specialized abrasion-resistant cover acts as a protective sleeve against constant rubbing and impact, significantly extending service life compared to standard hoses. For extra protection, external guards and sleeves are available.

Installation, Operation, and Maintenance Guide

1. Selection: Always verify the correct size, pressure rating, and specification for your application. Refer to the technical table above for ID, OD, and bend radius.

2. Assembly: Use only recommended crimped fittings or reusable fittings from reputable manufacturers. Ensure the hose is cut square and the correct amount of cover is stripped before crimping to create a secure, leak-proof hose assembly.

3. Routing: Never exceed the minimum bend radius. Avoid twisting the hose during installation, as this reduces pressure capacity. Use adapters and flanges to ensure proper alignment and relieve stress on the hose.

4. Inspection: Regularly inspect the hose cover for cuts, abrasion, or hardening. Check fittings for corrosion or leakage. For hoses in abrasive environments, consider using external protective sleeves or guards to extend service life.

5. Replacement: Replace the hose immediately if any signs of damage, leakage, or kinking are found. Always use a new hose of the same standard and specification.
