Long fatigue life and low bending radius: Meeting the need for braided hydraulic hoses

27 June, 2023

Another important point he makes, is that the selected hose will require validation with the fittings: “Only hoses with approved fittings will provide a safe and reliable assembly. Again, a reputable supplier will be able to offer expert advice.”

Further factors influencing hose selection decisions include fluid compatibility. Here, Pozzi says to try and source a hose that is not only highly suitable for conventional mineral-based hydraulic oils, but also the latest environmentally friendly biodegradable oils.

Pillar of support

Of course, finding the ideal hose for a specific application is one thing explains Pozzi, but will it come with the required levels of support? It is easy to treat a hydraulic hose as a commodity item, purchased from a catalogue or website, but this will likely come without customer or engineering back-up. A far wiser strategy he says, is to buy from a reputable manufacturer, particularly one that can demonstrate its credentials in R&D investment, engineering innovation and worldwide laboratory resources. Seek out a supplier with global customer and technical support, perhaps even one prepared to develop, manufacture, test and approve a hose (in one size) for a specific application. Not every hose manufacturer has the structure and flexibility to offer such a comprehensive service.

Choosing a supplier that works to international standards in production, quality and testing, is another clear benefit in support of hose reliability and safety. A leading hose manufacturer will likely have representatives from its engineering team on the steering committees of standards development agencies. As a further point of note, he highlights that you should always partner with a supplier that can demonstrate continuous improvement and regular investment in the latest hose manufacturing technologies
