Step 1: Choosing the Right Hose
The typical considerations when selecting a hose include size, flexibility, abrasion resistance, pressure rating, temperature range, and material quality.
More specifically, you should be able to answer the following questions:
What hose size is needed?
Choosing the correct internal hose diameter is crucial to ensure optimal flow rate and performance. A diameter that’s too small can reduce efficiency, while one that’s too large may cause excessive pressure and risk of leakage or damage.
What are the space constraints for hose routing? (Flexibility)
If installation space is tight, pay close attention to the hose’s bend radius. All hoses have a minimum bend radius they can withstand. Bending a hose beyond its limit weakens performance and lifespan – in the worst case, it could cause the hose to burst.
How resistant does the hose need to be? (Abrasion & Environment)
If your application requires extra durability, we offer hoses designed for tougher conditions. For example, hoses that rub against other materials face significant mechanical wear – one of the harshest stress factors. In such cases, consider adding our Safeplast protective sleeves or choosing MegaTuff® hoses.
Environments with aggressive elements can cause corrosion or rust on the spiral layers or reinforcement braiding. Harsh conditions include UV exposure, ozone, seawater, and chemicals. For these, XtraTuff® hoses are recommended. For UV exposure only, a Safeplast sleeve may suffice. If the hose is at risk of conducting electricity, opt for thermoplastic hoses, as they contain no metal.
Note: MegaTuff®, XtraTuff®, and thermoplastic hoses are not available in the hose configurator. For special configurations, please contact us at +45 97 35 05 99.
What fluid will flow through the hose?
Most hoses are compatible with mineral-based hydraulic fluids. However, if the hose material isn’t suitable for the specific fluid used, it can deteriorate faster, e.g., due to corrosion. Be sure to select the correct rubber compound and check the “Application Area” for fluid compatibility.
What is the fluid temperature?
Temperature also affects hose lifespan. Select a hose with the appropriate temperature range.
Check two values:
What pressure requirements does the hose need to meet?
Hydraulic hoses are rated for two types of pressure:
-
Working pressure – the pressure the hose must withstand during normal operation. Staying within the rated range is essential to maintain performance and durability.
-
Burst pressure – the pressure at which the hose will fail. This is typically at least four times the working pressure, but your focus should be on working pressure for safety and performance.
