The O-ring sits against the tube flange, the tube flange contacts the CNC'd flange metal to metal, just as the stock parts do. The silver ring inside the O-ring contains the O-ring in its cavity when it's compressed to provide the proper degree of squish.

You can rotate the tube with some force when the bolts are tightened down.
That is excellent design work!!! That allows for a tiny bit if head motion and still retain o-ring sealing. A few more hours on my bird and it is on the list for upgrade when the parts are off.

Keep up the good work, Team-Ross, kudos to Mike for initiative in action.
