Tool compatibility

  • 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.

Greater flexibility

  • MultiFit® pipes are easy to bend and to install and absolutely safe to use. They are optimised for the distribution of water on the respective floors

Greater safety

  • These SANHA fittings have two sealing rings for additional safety!

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.

Exceptional flexibility

  • All dimensions from 16 to 63 mm
  • Safe, permanent connection with:

    • MultiFit-Flex® multi-layer composite pipe from PE-RT/Al/PE-RT with hygienic inner layer, hermetically sealed aluminium layer and robust outer casing. Higher temperature stability.
