This quick connector features a supporting thread to ease the press in process of the PTFE tube.
The tube will be hold in place by the 2 holding rings on top.
Put some painters tape around the tube (leave >2cm free) to get a better grip.
start screwing 10mm in.
wait for 5min so the PTFE will deform and adapt the thread.
screw into final position by pressing and screwing until a tiny end protrudes.
press the protruding rim outwards by putting in some filament and bending out wiggling around to ensure smooth passage.
remove the tape and let it rest a day.
If you need a more secure connection you can add a drop superglue (CA) from the bottom - it will soak the thread and increase the form fit but keep in mind PTFE can't be glued.
