The hose core is made of extruded sintered polytetrafluoroethylene (PTFE), an 18/8 AISI 304 stainless steel braid outer sheath ensures protection and high resistance to working pressures.
The heating up is obtained by heating elements, at variable power, twisted around the hose core.
A sensor, inserted in the inner part, detects the temperature of the material and allows an external device to control the heating element to hold the temperature constant.
The end fittings are applied by means of a special process of cold deformation (pressing) which guarantees a perfect tightness even at a very high pressure.
The end covers and the polyamide sheath assure optimal mechanical strength, indispensable for manual application or hose movement.
The manufacturing of the heating hoses satisfies strict internal and external controls.
The production is entirely tested.



PTFE can be considered the "noble" polymer par excellence, thanks to its really unique combination of valuable features, such as low friction factor, excellent chemical inertia, extremely anti-adhesive surface, high resistance to high and low temperatures, excellent dielectric properties, ideal relationship between rigidity and flexibility, excellent resistance to humidity, non-existent volumetric expansion. The only elements which can damage it are: alkaline metals in a molten state (e.g. sodium and potassium) and some fluorinated chemical compounds (fluorine in a gaseous form, chlorine fluoride, etc.).
