Hydraulic hose

Frequently asked questions — Hydraulic Hoses

• What are the key technical criteria for choosing a hydraulic hose?

  The choice of a hydraulic hose must be based on the working pressure, the inner diameter and the nature of the fluid conveyed. It is also essential to take into account the environmental constraints specific to the installation site, in particular extreme temperatures and vibration. Ensuring the installation complies with the operating requirements of the associated hydraulic components guarantees the integrity and longevity of the system.
• Why is compatibility with crimp fittings critical?

  Hydraulic hoses are closely associated with the use of crimp fittings and specific adaptors to ensure optimal sealing of the connection. Compatibility with crimping equipment is decisive in guaranteeing the mechanical strength of the assembly under pressure. A mismatch between these connection elements and the hose can compromise the integrity of the assembly and the safety of the hydraulic circuit.
• Which standards must be observed when designing hydraulic circuits?

  For the representation and design of circuits incorporating hydraulic hoses, professionals refer to the graphical symbols defined by the ISO 1219 standard. When the installation involves integrating elements into more complex systems, such as the mounting of directional control valves, the connection interfaces must comply with the requirements standardised by ISO 4401. Adherence to these standards ensures functional compatibility between the various hydraulic components.
• How do I choose between the different hydraulic hose manufacturers on offer?

  The MecaIndus catalogue features products from well-known manufacturers such as GATES HYDRAULIQUE, KUTTING FRANCE, ALFAGOMMA and GATES. The selection is not based on the intrinsic superiority of any one brand, but on the ability of the chosen reference to meet the technical constraints of your installation. You should review the technical data sheet for each product to ensure that its characteristics match the pressure, temperature and fluid compatibility requirements of your application.
