Hoses have become an indispensable part of our everyday lives and modern industry. As flexible lines, they enable the safe and efficient transport of liquid and gaseous media in a wide range of applications.
From garden irrigation to complex production facilities to medical technology – hoses are the invisible heroes that ensure smooth operations.
But the world of hoses is diverse and complex. Different materials, properties and areas of application require a well-founded selection in order to find the optimal solution for your individual needs.
In this comprehensive guide, we take you on a journey through the world of hoses. Find out everything you need to know about their properties, areas of application and the wide selection that Rexio® offers you. Discover the perfect hose solution for your individual requirements!

What are hoses? – Structure and function of flexible lines
A hose is essentially a flexible pipe designed to transport liquid or gaseous media. Its structure usually consists of several layers:
Core: The inner layer that is in direct contact with the medium. Its material properties determine the chemical resistance and temperature resistance of the hose.
Reinforcement layer: This optional layer, which is located between the core and the ceiling, provides additional stability and pressure resistance. Depending on the requirements, it can be made of various materials such as textile fabric, steel wire or plastic mesh.
Cover: The outer layer protects the hose from external influences such as mechanical stress, weather or chemicals.
The combination of these layers enables the production of hoses with specific properties that are optimized for the respective application.
Material diversity – the right choice for your application

Thermal properties – temperature resistance and thermal conductivity
The thermal properties of hoses are crucial for use in different temperature ranges.
Temperature resistance: Each hose type has a specific temperature range in which it can be used. Silicone hoses, for example, can be used up to +200°C, while PTFE hoses can even withstand temperatures up to +260°C.
Thermal conductivity: Thermal conductivity plays a role when the hose is used for insulation. Hoses with low thermal conductivity prevent heat exchange between the medium and the environment.
Mechanical properties – flexibility, compressive strength and more
The mechanical properties determine the resilience and service life of a hose.
Pressure resistance: Hoses must withstand the pressure of the medium being transported. The pressure resistance is given in bar and varies depending on the hose type and design.
Bending strength: Hoses must be flexible and must not kink when bent. The bending strength depends on the material and construction of the hose.
Tensile strength: Hoses must be able to withstand tensile forces that occur, for example, during transport or installation.
Abrasion resistance: Hoses should be resistant to abrasion and wear, especially when used in harsh environments.
Acoustic Properties – Sound Insulation in Hose Technology
In some applications, the acoustic properties of hoses also play a role.
Sound insulation: Hoses can be used for sound insulation, e.g. in ventilation technology or in mechanical engineering. The sound level can be reduced by using sound-absorbing materials in the hose or in the hose sheath.
Hoses in use – diverse applications in all industries
Hoses are indispensable in almost all industries. They are used in:
Food industry: transport of food, beverages, flavours,
Chemical industry: extraction of chemicals, acids, alkalis,
Pharmaceutical industry: Transport of pharmaceutical products, active ingredients,
Automotive: fuel lines, cooling water lines, brake lines,
Medical technology: infusion tubes, catheters, dialysis tubes,
Laboratory technology: Transport of liquids, gases,
Agriculture: irrigation, fertilization,
Construction: concrete conveying, water supply, drainage,
