Installers value the quick, convenient and reliable installation that is also possible in difficult to access spaces. In addition, the large number of available tube dimensions give fitting manufacturers and end customers maximum flexibility so they can offer and realise tailored solutions.

Tube requirements

• Excellent formability
• Homogeneous strength and elongation
