Product Overview


This variant, the Smooth Cover High Pressure EN853 1ST Synthetic Hose, represents the upper performance tier within the EN853 1ST classification. Engineered to meet the stringent EN853 1ST standard, it utilizes premium materials and construction techniques to deliver enhanced working pressure ratings compared to standard EN853 1ST hoses. Featuring a smooth synthetic rubber cover and reinforced with high tensile steel wire braid, it provides reliable high-pressure fluid conveyance for demanding hydraulic systems using mineral oils and certain bio-fluids, while maintaining the clean ability advantages of a smooth exterior.


Key Features


Enhanced Pressure Rating: Manufactured with optimized materials and processes to achieve significantly higher working pressure capabilities than typical EN853 1ST hoses, suitable for more demanding hydraulic circuits.


High Tensile Steel Braid: Reinforced with a robust layer of high tensile steel wire braid, providing the core strength necessary for high-pressure operation.


Premium Smooth Cover: Features a durable, smooth, black synthetic rubber cover offering excellent resistance to abrasion, oil, weathering, and ozone, ensuring long life and easy cleaning.


Compatible Fluids: Suitable for use withmineral hydraulic oils (HH, HL),HETG (vegetable oil),HEES (synthetic ester), and water-glycol (HFC) fluids within specified parameters.


Temperature Resilience: Operates effectively within a wide temperature range, typically-40°C to+100°C .


Applications


The Smooth Cover High Pressure EN853 1ST Synthetic Hose is deployed in applications requiring robust medium-to-high pressure performance:


High-Pressure Industrial Systems: Heavy-duty presses, machine tools, plastic extruders, and other industrial machinery where hydraulic pressures exceed standard EN853 1ST ratings.


Demanding Mobile Hydraulics: Critical functions on construction, mining, forestry, and agricultural equipment operating under high hydraulic loads.


Power Packs and Units: Hydraulic power sources supplying high-pressure fluid to various tools and actuators.


Systems Using Bio-Fluids: High-pressure applications utilizing HETG or HEESwhere environmental compatibility is required.


General High-Power Hydraulics: Any hydraulic system necessitating the strength of high tensile steel braid and the higher pressure capability of this enhanced 1ST hose.


FAQ


Q: How does the pressure rating compare to a standard EN853 1ST hose?

A: This High Pressure EN853 1ST Synthetic Hose offers significantly increased working pressure ratings across all sizes compared to a standard EN853 1ST hose. Always refer to the manufacturer's specific pressure tables for the exact values.

Q: Is the construction different from a standard EN853 1ST hose?

A: While adhering to the EN853 1ST standard framework for single wire braid construction, this high-pressure variant utilizes premium quality synthetic rubber compounds for the tube and cover, along with potentially higher tensile strength wire, to achieve its enhanced pressure performance.

Q: Can it be used with the same fluids as the standard version?

A: Yes, compatibility generally includes mineral hydraulic oils,HETG, and HEES, similar to the standard EN853 1ST Synthetic Hose. Confirm specific fluid compatibility with manufacturer charts.
