A hydraulic hose is a flexible pressure line that carries hydraulic fluid between pumps, valves, cylinders, motors and attachments. In simple terms, it is the moving artery of a hydraulic system. The hose must hold pressure, resist oil, bend around equipment and survive vibration, heat, dust and abrasion.
What Does a Hydraulic Hose Do?
A hydraulic hose transfers energy through pressurized fluid. When the pump creates flow, pressure builds against a load. The hose must safely contain that pressure while allowing movement between fixed and moving machine parts.
| Item | Practical meaning for buyers |
| Inner diameter | Controls flow rate and pressure drop |
| Working pressure | Maximum recommended continuous pressure |
| Burst pressure | Short-term failure pressure, often 4 times working pressure for many hydraulic hose families |
| Minimum bend radius | Smallest safe bend without damaging reinforcement |
| Temperature range | Common hydraulic hose compounds are often around -40 C to +100 C or +121 C depending on hose type |
Common Hydraulic Hose Families
| Hose family | Typical reinforcement | Common pressure level | Typical applications |
| SAE 100R1 / EN853 1SN | 1 steel wire braid | Medium pressure, often 40-225 bar by size | Agriculture, forklifts, standard hydraulic lines |
| SAE 100R2 / EN853 2SN | 2 steel wire braids | High pressure, often 80-400 bar by size | Excavators, loaders, presses, mobile equipment |
| EN856 4SP / 4SH | 4 spiral wires | High pressure, commonly severe-duty range | Construction, mining, heavy mobile hydraulics |
| SAE 100R13 / R15 | 4 or 6 spiral wires | Very high pressure, often constant pressure series | Large excavators, mining, drilling and severe impulse circuits |
Where Hydraulic Hose Is Used
Hydraulic hose is used in excavators, loaders, cranes, tractors, harvesters, forklifts, hydraulic presses, injection molding machines, palm oil equipment, marine power units and maintenance workshops. Each industry has different failure risks: mining faces abrasion and pressure shock; agriculture faces dust, mud and seasonal repair urgency; manufacturing needs clean routing and repeatable replacement.
Beginner Selection Checklist
- Confirm old hose marking or machine specification.
- Measure inner diameter and total assembly length.
- Check working pressure and pressure spikes.
- Match thread standard, fitting angle and ferrule series.
- Check oil type, temperature and outdoor exposure.
- Do not select only by outer diameter or price.
FAQ
Is hydraulic hose the same as industrial hose?
No. Hydraulic hose is designed for pressurized hydraulic oil circuits. Industrial hose may carry air, water, oil, chemical, suction or discharge media and often has different pressure and tube material requirements.
Can any fitting be crimped on any hose?
No. Hose, fitting, ferrule and crimp diameter must be matched as a tested assembly system.
