Is this a "defective O-ring" issue, or could it be the parts where the O-ring creates a seal in between are connected to different "fixed" parts, which in turn can move (as designed) relative to each other ?

Or so to say, is this a design issue ? O-rings normally don't structurally fail, unless something is overseen in the design (IE moving parts, over pressure, temperature range or housing expansion effects, etc).

Not a word about this aspect in the FAA instruction. Worrying.
