Hydraulic hose pressure rating tells you how much pressure a hose can safely handle in service. It is one of the most important selection values, but it should never be read alone. Temperature, impulse, bend radius, fittings and routing all affect safe performance.
Working Pressure vs Burst Pressure
| Term | Meaning | Buyer note |
| Working pressure | Maximum recommended continuous operating pressure | Select equal to or above system pressure |
| Burst pressure | Pressure where the hose may fail in a burst test | Often around 4 times working pressure for many hydraulic hose standards |
| Proof pressure | Factory test pressure above working pressure | Used for quality control, not normal operation |
| Impulse pressure | Repeated pressure cycling | Critical for mobile machinery and severe duty |
Typical Pressure Ranges by Hose Family
| Hose family | Typical reinforcement | Practical pressure reference |
| SAE 100R1 / EN853 1SN | 1 wire braid | Often 40-225 bar depending on size |
| SAE 100R2 / EN853 2SN | 2 wire braid | Often 80-400 bar depending on size |
| EN857 1SC / 2SC | Compact wire braid | High pressure with tighter routing than standard braid |
| EN856 4SP / 4SH | 4 spiral wires | High pressure severe-duty applications |
| SAE 100R13 / R15 | 4 or 6 spiral wires | Very high pressure, often constant-pressure families |
Why Same Hose Standard Has Different Pressure by Size
A smaller hose ID can usually handle higher pressure than a larger ID in the same family. This is why buyers should not ask only for SAE 100R2 or 4SP; the size is essential.
Industry Examples
- Agriculture: moderate pressure lines may use 1SN or 2SN, but harvesters and loaders may require higher pressure options.
- Construction: excavator boom, arm and attachment lines often need two-wire or spiral hose due to pressure shock.
- Mining: severe impulse and abrasion make pressure rating plus reinforcement choice critical.
- Manufacturing: pressure may be stable, but leakage control and repeatable spare parts matter.
Common Mistakes
- Using burst pressure as if it were working pressure.
- Ignoring pressure spikes from valves and attachments.
- Choosing hose by outside diameter instead of ID and marking.
- Mixing hose and fittings without tested crimp data.
FAQ
What safety factor should hydraulic hose have?
Many hydraulic hose families are designed with a burst pressure around four times the working pressure, but always confirm the manufacturer datasheet and applicable standard.
Does higher pressure rating mean longer life?
Not always. Routing, abrasion, temperature, impulse and assembly quality can destroy an over-rated hose if installation is wrong.
