3fit Press Fittings T-stück

Want to know more about our plastic fittings & multi-layer pipes?

Our 3fit®-Press system press fittings are made of a special lead-free copper alloy called silicon bronze (or CuSi in short). This lead-free material makes them optimally suited for use in a system with MultiFit®-Flex and MultiFit®-PEX multi-layer plastic pipes in any drinking water system. The fittings are a WRAS approved product. 

What is more: 3fit®-Press fittings are also certified by all relevant international institutions such as DVGW, CSBT or KIWA. Of course, their use is not limited to drinking water. Please find out more about all possible applications further down below.

Did you know about our Tool compatibility?

  • 3fit®-Press fittings can be pressed with all jaws and slings with an original TH, B, F, H and U contour up to and including 63 mm

So you want an easy installation? 

  • The Push & Stay function allows you to do just that. Without help, in tight spaces and with two hands instead of three - for a 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 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
