Polyurethane hoses

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

• Materials: PUR, PA, PP 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 and resistant to welding spatter
• 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

Reinforced corrugated hoses

For industrial applications, especially related to robot equipment, LEONI has developed corrugated hoses made of specially modified plastics as guide and protective media for umbilical components / dresspacks. Corrugated hoses are suited especially to dynamic movement, which calls for a greater abrasion property as well as torsion and elongation resistance.
