Allow for the easy removal of AMS hub PTFE tubes without the need for tools or frustration. I've tried several PTFE release buttons, and none would stay in place reliably. This design features three evenly spaced clips to hold the buttons in place, regardless of their rotation. Works with both for P1 and X1series.
To install, remove each PTFE tube, snap the buttons into the hub, and then reinstall the tubes.
