Product Overview


The Smooth Cover EN853 1ST Synthetic Hose a robust hydraulic solution designed for medium-pressure applications demanding high flow rates. Manufactured in strict compliance with the EN853 1ST European standard, this hose features a smooth, abrasion-resistant synthetic rubber cover and utilizes a single wire -mentioned layer. It is engineered to reliably transport mineral oil-based hydraulic fluids (HH, HL), HETG (vegetable oil), and HEES (synthetic ester) fluids within industrial and mobile hydraulic systems, offering a balance of performance and durability with an easily cleanable exterior.


Key Features


EN853 1ST Compliance: Adheres precisely to the EN853 1ST specification, ensuring standardized performance, dimensions, and safety for hydraulic systems in European and global markets.


High Tensile Steel Braid: Reinforced with a layer high tensile steel wire braid, providing the strength required for medium-pressure applications defined by the 1ST standard.


Smooth Synthetic Cover: Features a smooth, black synthetic rubber cover offering superior resistance to abrasion, weathering, ozone, and hydraulic oils, while promoting cleanliness.


Applications


The Smooth Cover EN853 1ST Synthetic Hose widely employed in numerous medium-pressure hydraulic scenarios:

Industrial Hydraulics: Machine tools, presses, injection molding machines, steel mills, and general factory automation systems mineralogist oil or bio-degradable fluids.


Mobile Machinery: Hydraulic circuits on construction equipment (excavators, bulldozers), agricultural tractors and harvesters, forestry machinery, and material handling equipment.


General Fluid Transfer: Reliable conveyance of compatible hydraulic fluids in any system requiring EN853 1ST performance.


FAQ


Q: Is this hose suitable for high-pressure applications?

A: The EN853 1ST Synthetic Hose is designed for medium-pressure applications. For higher pressures, EN853 standards define types like 2SN (two steel braids) or 4SP (four steel spirals). Always verify the required working pressure for your application.


Q: Can this hose handle water-based fluids?

A: While primarily for oils, the Smooth Cover EN853 1ST Synthetic Hose can be compatible with water-oil emulsions (HFA, HFB) and water-glycol (HFC) fluids within specific concentration and temperature limits. Consult manufacturer data for precise compatibility details.
