Spiral pneumatic hoses – general information

Spiral pneumatic hoses are designed for connection of movable parts in wide range of applications, present in practically all branches of industry. Spiral pneumatic hoses designed for:

  • connecting pneumatic tools,
  •  pneumatic control systems,
  • application in car workshops in particular,
  • air brake systems, connects the air lines from the tractor to the trailer,
  • components of industrial robots ,
  • and other industries.

Made of polyamide (nylon) or polyurethane and available with straight end fittings or male threads.

DIN 73378The standard applies to polyamide hoses used in motor vehicles. The hoses complying with this standard have undergone several tests and examinations (material density test, melting point, impact tests over a wide temperature range, and thermal stability tests). The dimensions of the hose (wall thickness, inner and outer diameter) are also standardised. The name of the hose contains special markings: P, H, L, HI, Y. According to the standard, the material which the hose is made of, may contain additives to improve some of its technical parameters, including thermal stability (H), light stability (L), crack resistance (HI), plasticity (P), resistance to high pressure (Y).
DIN 74323Applies to spiral polyamide hoses used in air braking hose assemblies of motor vehicles.Specifies test procedures and test methods for polyamide hoses used in air braking systems of motor vehicles. The test covers such parameters as density, melting point, water content, chemical resistance (testing for mineral oil, silicone oil, water, etc.), resistance to dynamic stress cracking and thermal stability.
DIN 74324Applies to single, straight polyamide hoses used in air braking hose assemblies of motor vehicles.
ISO 7628The standard applies to single-layer and multi-layer straight thermoplastic hoses used in air braking systems of motor vehicles.Specifies test procedures and test methods for polyamide hoses used in air braking hose assemblies of motor vehicles. These tests cover, e.g. surface quality, deformation under pressure, cold impact, ageing, moisture absorption, low-temperature flexibility, stress cracking, resistance to ethanol, battery acid, oil, urea solution, and ozone.
ISO 7375The standard applies to spiral thermoplastic hoses used in air braking systems of motor vehicles and their trailers.
