  • Ideal for the construction of drinking water distribution systems.
  • Corrosion resistance, hygiene and reliability.
  • Excellent behaviour of the material against ageing, sunlight, weather, alkaline substances.
  • Speed of operation, saving time and offering increased productivity levels.
  • Gaskets can be fitted without welding, eliminating the risk of fire in more hazardous situations (working in older buildings, furnished rooms, etc.).
  • No need for dangerous gas pumps or containers, completely eliminating the need to make the connections required by law.
  • Elimination of all welding materials, with inevitable cost benefits.
  • Junctions free from burning or rings with an excellent immediate visual impact.
  • Integrity of pipe insulation thanks to the absence of heat sources.
  • Increased wall thickness to ensure the reliability and durability of junctions and fittings.
  • Polygon-shaped press designed to ensure maximum resistance to traction and torsion stresses.
  • Precision cleaning of internal surfaces to eliminate oily residues due to processing and to ensure protection against rust under all operating conditions.
