EN/DIN (European/German Standards): The core European specification, highly corresponding to the SAE standards and widely adopted.
This is the most common type. It is reinforced by weaving one or more layers of high-strength steel wires. Its characteristics include good flexibility and a smaller bending radius, but it has relatively weaker resistance to pulse high pressure.
Model | Standards | Core Construction | Pressure | Typical Applications |
R1AT/EN853 1SN | SAE 100R1AT/EN853 1SN | single layer of steel wire braided | Medium-low pressure | The lubrication circuit of machine tools and the pilot control line of construction machinery require flexible hose distribution and low pressure situation |
R2AT/EN853 2SN | SAE 100R2AT/EN853 2SN | two layer of steel wire braided | medium-high pressure | The main hydraulic circuits of equipment such as excavators, loaders, and injection molding machines are the most widely used. |
1SC/2SC | EN 857 1SC/2SC | single/two layer of steel wire braided,with a compact structure | higher than the same grade braided hose | In compact spaces, its bending radius is smaller than that of the EN853 series. |
R6 | SAE 100R6 | single layer of fiber or steel wire braided | low pressure | Low-pressure oil return or suction line. |
R16 | ISO 112 37 | Compact steel wire braid | medium-high pressure | Between R2 and R17. |
When the system pressure is higher and the pulses are more intense, a wire winding structure is required. It winds the wire in a spiral pattern in multiple layers to provide stronger support for the hose.
Model | Standards | Core Construction | Pressure | Typical Applications |
4SP | EN 856 4SP/SAE 100R12 | four layers of high strength steel wire spiral winding | high pressure | High-pressure and shock-prone conditions, such as the piping system of hydraulic hammers and the pressurization systems of large-scale presses |
4SH/R9 | EN 856 4SH/SAE 100R9 | four layers of high strength steel wire spiral winding | high pressure | Usually similar to 4SP, but performance requirements may be higher. |
R12 | SAE 100R12/EN 856 R12 | four layers of spiral wire winding | high pressure | High-pressure and high-pulse applications, with performance and pressure superior to 4SP |
R13 | SAE 100R13/EN 856 R13 | four to six layers of high-strength steel wire spiral winding | extremely pressure | Applications such as mining that involve extremely high pressure and high pulse impact |
R15/6SH | SAE 100R15/EN 856 R15 | six layers of spiral wire winding | extremely high pressure | Static hydraulic transmission, large-scale mining equipment and other extremely heavy-load working conditions |
