If you need more grip on the PTFE tubing on your Tough Extruder you can print a small clip that will apply more pressure on the fitting to grip the tubing. This may be needed for slicker PTFE tubes like our Tough Tube or Capricorn type tubes.
See attached ZIP files for various PTFE clips that have been verified by us to fit the fitting on the Tough Extruder.
Files are download from Thingiverse. Source links are in the ZIP files and here:
