Hoses & tubes

General information

We develop and produce all the polyurethane hoses for integration in umbilicals / dresspacks. Our polyurethane hoses are used in many industrial applications, e. g. on industrial robots. They are utilised to transmit air, water and gases, or also as tubes to convey and position solid states such as rivets, bolts etc.

LEONI tube-fit PUR-line

Reinforced two layer polyurethane hoses – self-locked

Especially recommended for robotics equipment and machines, our hoses are built to comply with the most demanding conditions.

  • Materials: PUR, PA and special compounds
  • Single-layer construction
  • Twin-layer construction with fiber braid reinforcement sealed between two extruded polyurethane layers
  • High abrasion resistance
  • Seven different standard colours (special colours optional)
  • Cross sections from 1/4" to 1"
  • Self extinguishing, complies with UL94 V2 and MSHA standards
  • Resistant to welding spatters
  • Resistant against hydrocarbons, bacteria, caustic solutions etc.
  • Temperature range from –20 °C to +80 °C (continuous use)
  • Limited elongation (1.5 % at 20 °C and 150 psi)
  • UV and ozone resistant
  • 100 % silicone free
Fittings

Corresponding to the polyurethane hoses LEONI tube-fit PUR-line we offer diverse fittings, such as brass fittings, straight, 45° or 90° angled. The installation of self-locked polyurethane hose on fittings is simple and fast.

  • Our specific hose tool guarantees an easy mount without deterioration
  • Dry mount
  • Installation without hose clamp and without crimping with most of the standard fittings

LEONI tube-fit FR-line

Polyurethane hoses

For industrial applications, especially for robotic and welding equipment LEONI has developed the half-stiff and flame-retardant polyurethane hoses as a transmission medium for compressed air and (cooling) water.

Mechanical and chemical properties

  • Silicone free
  • Halogen free
  • Flame resistant, according to UL 94-V0, self-extinguishing
  • Resistance to oils / mineral oil / oxygen / ozone / weak acids / diluted bases
  • UV resistant
  • Abrasion resistant
  • Working temperature range: –30 °C to +90 °C 

Corresponding to the polyurethane hoses LEONI tube-fit FR-line we offer female thread and male thread fittings, e. g. rotatable, 90° angled.

LEONI tube profile-line

Polyurethane hoses for feeding applications

These special tubes with customised inside and outside profile are for example used for rivet and weld nut delivery systems in the automotive and aviation industry. They can be implemented for other feeding applications as well.

Mechanical and chemical properties

  • Inner and outer layers are 100 % paint resistant
  • Silicone free
  • Halogen free
  • Resistance to oils / mineral oil / oxygen / ozone / weak acids / diluted base
  • Abrasion and scratch resistant, resulting in a longer life-cycle 
  • High cross sectional strength
  • Standard temperature range: 0 °C up to +50 °C
  • Colour: transparent to crystal clear
  • Inside and outside profile: customised to specification
  • Construction: reinforced if needed
  • Technical characteristics for working pressure, burst pressure and vacuum can be modified in accordance with the application and the customer‘s needs.
