Dual hose System PFA/PVC - ultra flexible with corrugated PFA tubing

The perfect combination of ultra-flexible PFA corrugated tubing and protective PVC hose for double containment.


  • Minimum bending radius
  • High flexibility can replace rigid piping
  • More stable compared to usual corrugated PFA tubing due to inwards corrugation
  • Different ultra pure PFA qualities available on request
  • Reliable sealing from Flare and anti-kink nut and outside hose; thus provides safety even in case of a leak on the PFA core hose
  • Possible to fit sensors, e.g. capacitive sensors, temperature sensor or conductivity sensor
  • Perfect in combination with the QC-System

Core hose made of PFA:

The chemical and physical properties of PFA tubes are largely identical to those made of PTFE.
They have an outstanding and almost universal resistance against most chemicals, are ultra-pure and can be used for pharmaceutical applications. The key differences to PTFE are: lowercold flow, improved mechanical properties, lower diffusion, higher purity and better translucency. PFA can be welded.
