System description

Practical Push-fit system with a safe and innovative lock function made using a copper alloy, similar to that used in the SANHA MultiFit®-Flex and MultiFit®-PEX multilayer composite pipes. All 3fit® components from SANHA are made in accordance to DVGW W 542 for heating installations, especially underfloor heating systems or other surface heating systems.

3fit®-Push system fittings offer a safe and reliable connection like the SANHA 3fit®-Press fittings (lock function) due to their ingenious design. The plug-in connection can be made quickly and requires no tools. This means that when 3fit®-Push  fittings are used, no costs are incurred for the purchase, maintenance or repair of  machine tools.

3fit®-Push plug-in fittings are ideal for applications where space is at a premium, such as building refurbishment, and ideal for instant repairs on older systems that require maintenance. 

The 3fit®-Push system has been tested in accordance with DVGW Code of Practice W 534.

Operating conditions 3fit®-Push with MultiFit®-Flex multi-layered plastic pipes d ≤ 20 mm

Features of the 3fit®-Push fittings

  • Practical handling: With 3fit®-Push system fittings, connections can be made quickly, flexibly and permanently by simply plugging in
  • No tools required: The innovative plug-in connection means that no tools are required, there is no wear and tear and there are no special costs for tool maintenance
  • Small footprint: The 3fit-Push system is ideal for tight environments, such as refurbishment, due to the small footprint required when making the connection
  • Protection against corrosion: The system is extremely resistant to  dezincification and stress corrosion cracking (e.g. in drinking water installations). The extremely clean surface of the system fittings also contributes to this.
  • Secure connection: Permanently tight connection with the following pipe types:
    • MultiFit®-Flex multi-layer composite pipes PE-RT/Al/PE-RT with hygienic inner jacket, hermetically sealed aluminium layer and robust outer jacket. Higher temperature stability according to DIN 16833.
    • MultiFit®-PEX multi-layer composite pipes made of PE-Xc 16 and 20 mm, oxygen-tight 5-layer pipes with a special plastic oxygen barrier EVOH (not for drinking water pipes)
    • MultiFit® PE-RT multi-layer composite pipes made of PE-RT 16 mm, roll 400 m, oxygen-tight 5-layer pipes with a special plastic oxygen barrier EVOH (not for drinking water pipes)
  • Suitable for panel heating systems up to a maximum of 6 bar
  • Available in the dimensions 16 to 20 mm
  • Transition thread to EN 10226 or ISO7/1 Type R and Rp
