Push to connect fitting for extruder on UM2?

[muttstang 8]

Has anyone tried using a push to connect type of tube on an extruder upgrade by chance?

I have a design and left provisions for a 1/8" NPT fitting and am trying to figure if a push to connect will work instead of a compression type of fitting.

A push to connect fitting will generally allow the tube to be pulled out slightly so I don't know if this would cause issues. A compression fitting will be more of a rigid connection.

I don't know if anyone has tried but if the bowden is allowed to move up and down it will affect retraction (it has to "take up the slack" before the actual retraction starts). You want the tube to be stuck in there without moving.

I have that kind of fitting on both my extruder and hot-end, after installation I checked if the bowden can move up and down , it doesn't.

Currently no picture of it by hand, but if you like I can make one this evening.
