Polyurethane (PU) hoses are made with an internally integrated metal or PVC spiral. These hoses are highly resistant to wear and pressure.

Polyurethane hoses with a metal spiral are intended for transporting light materials such as chips, sawdust, dust. Also for transporting grease or gasoline vapors, for ventilation.

Polyurethane hoses with a PVC spiral are used for the transportation of abrasive and granular materials, such as: wood pellets, cement, sand, grains or other bulk materials.
