Fastening thread: G thread according to EN 228
...pressable with press jaws and slings with original TH, B, F, H and U contour up to and including 54 mm
Push & Stay function
...for safe, reliable installation in every position
Unique lead-free alloy
...our specially developed completely lead-free material silicon bronze CuSi helps to fulfill the strict Drinking Water Directive (DWD). Installers are always safe from any legal claim should the lead concentration exceed the tolerances set forth in the DWD.
...MultiFit® pipes are easy to bend and to install and absolutely safe to use. They are optimized for the distribution of water on the respective floors
...these SANHA fittings have two moulded sealing rings!
Fast installation, no risk of fire
...the connection with multi-layer pipes by cold pressing enables a fast, time-saving installation and eliminates the risk of fire during the process. 3fit®-Press installation systems are therefore ideally suited for renovation work.
High corrosion resistance
...the extremely smooth surface of our system fittings leads to an exceptionally high corrosion resistance. No porosity of the casting due to high material density.
