Choosing between braided or spiral hose?
What pressure (psi) is needed?
Choosing between a braided or spiral hydraulic hose depends on several factors.
Braided hose:
Flexible | Tighter bend radius | Compact applications with frequent movement | Medium/High pressure
Braided hoses are ideal for applications requiring flexibility and a tighter bend radius, making them suitable for installations with limited space or where frequent movement occurs. They provide excellent resistance to abrasion and are often preferred for medium-pressure hydraulic systems.
Spiral hose:
Rigid | Strong | Heavy-duty machines or industrial settings | High pressure
Spiral hoses are better suited for high-pressure applications due to their reinforcement structure, which offers greater strength and support under intense pressure conditions. They are commonly used in heavy-duty industrial settings or machinery requiring robust hydraulic performance.
Ultimately, the decision between braided and spiral hoses should consider the specific requirements of the hydraulic system, including pressure levels, flexibility needs, and environmental factors, to ensure optimal performance and longevity.

Spiral –

Hydraulic hose FAQs
Critical considerations when selecting a hydraulic hose
Temperature
- Temperature significantly impacts hydraulic hose performance, durability, and safety.
- Hoses are designed for specific temperature ranges, exceeding which can cause degradation, leakage, or system failure.
- High temperatures can soften or weaken hoses, increasing the risk of bursts, while low temperatures can cause stiffness or cracking, impeding fluid flow.
- Selecting hoses based on temperature conditions is crucial for optimal performance, reliability, and longevity.
- Considering temperature factors during hose selection mitigates risks, enhances system efficiency, and prolongs hydraulic component lifespan.
Fluid compatibility
- Fluid compatibility is crucial when choosing a hydraulic hose.
- Using the wrong fluid can damage both the hose and the entire system.
- Different fluids have varying properties; using an incompatible one can degrade hose materials over time, leading to leakage or system failure.
- Incompatible fluids may compromise seals and other components.
- Ensuring the hose is compatible with the fluid used is essential for maintaining performance, reliability, and safety.
Hose size
- Choosing the right hydraulic hose size is vital for optimal performance and safety.
- A hose that is too small can restrict fluid flow, leading to inefficiencies and potential overheating.
- Conversely, an oversized hose may cause fluid leakage and reduced system responsiveness.
- Consider factors such as flow rate, pressure requirements, hose length, and fitting compatibility to determine the correct size.
- Consulting system specifications and seeking guidance from manufacturers can help identify the best hose size for your application.
Industry standards & certifications
- Industry standards and certifications ensure hydraulic hose quality, reliability, and safety.
- Organizations like ISO and SAE set rigorous standards covering factors such as size, construction, and performance.
- Compliance assures users of hoses meeting criteria for durability, pressure ratings, temperature ranges, and resistance to abrasion.
Impulse life
- The hydraulic hose impulse life cycle measures a hose’s durability and performance under pressure surges or impulses.
- Hydraulic systems often experience pressure fluctuations due to rapid changes in fluid flow, exerting stress on the hose.
- If not designed to withstand such conditions, the hose may weaken or fail.
- Manufacturers subject hoses to standardized impulse tests simulating real-world conditions, quantifying their ability to withstand pressure surges without degradation.
- Selecting hoses with appropriate impulse life ratings ensures reliable performance, minimizing the risk of unexpected downtime.
