Push fit fitting not sealing?

[Fred Trevvett]

Hello,

Any suggestions on how to help a 6mm push fit compressed air fitting seal? It's inside one of the machines at work, bit of a poor design but every time the machine moves (it's a heat press, swings from one plate to another) it causes the pipe to rotate in the fitting, which I'm sure can't be doing it any good for context, it's swinging probably an average of 600-800 times a day, turning the pipe back and forth 90° each time. Any suggestions will be considered, but I would like to keep it looking as original as possible as I don't want to void the warranty. (Yes I know we could just get the air leak fixed under warranty but we've already tried that and it's started leaking again so it's clear it's a bad design rather than faulty parts)

It won't as that's not what they are supposed to do.

Fit a longer length of tubing, re-routed and clamped down so it doesn't move in the fitting, make the pipe roll/flex (but not twist) to take the movement.

Or fit a proper rotary union or rotary joint (and not simply a fitting that will allow you rotate into position)
