Any feedback on using this? It seems viable - the PTFE should glide well. Lack of a debris gasket might end up being an issue. Not sure how well the PTFE tubing would handle whatever forces are applied. My search doesn't seem to show anything equivalent - as in, using PTFE.

This has already been published a few times. Never got any feedback about its use though. Quite normal as it is unsuitable.

why is it unsuitable?

Do a search for the same designs, it is explained there. People here keep reinventing the wheel, yet they often fail.
