History of Air Hoses

History of Air Hoses

Many industries employ air hoses. For example, heavy-duty air hoses are used to supply power to the brakes located between locomotive cars or within a standard lorry. In these cases, air replaces standard hydraulic fluid. These will normally be connected to a gauge, for internal pressures can reach as high as 300 bar (4,400 pounds per square inch).


Without the rather humble air hose, many modern technologies would simply cease to exist. The main principle behind any of these hoses is to carry air from one point to another. .  Radiator hoses can be made of various materials and this will primarily revolve around their purpose as well as the pressure of the air contained within (usually measured in “bars”).  Some common substances include plastic, uPVC, rubber and even polymers reinforced with a metallic mesh.

Other air hoses are meant for entirely human uses.  One instance can be seen in the typical scuba diving suit.  Pressurised air enables divers to descend to depths which would not be possible with surface diving methods alone.  Other hoses are attached between the regulator and ancillary accessories.  A buoyancy compensator and a drysuit will also employ the use of the air hose.

History and Development

The concept of using common air within mechanical devices has existed for centuries. However, the low tensile strength of traditional materials only supplied a limited number of applications. It was not until the development of plastics and strong polymers (combined with reinforcing materials) that these hoses were finally able to handle higher internal pressures without failing.

Many modern air hoses are comprised of space-age substances including carbon fibre filaments. Not only do these materials offer a massively increased strength, but their lightweight nature enables them to be used in demanding applications such as those which are often encountered within the aerospace industry.

Whether referring to standard plastic hoses or innovative composite variants, the air hose has become an essential piece of hardware within our daily lives. As the technology behind these devices continues to advance, it is likely that even more uses will be discovered in the future.
