I am a bit late with this reply, but using glue to hold the O-rings is not a good idea. As the mating surfaces come together, the O-ring is supposed to move as necessary to fill in any gaps. Coating the o-rings with grease makes them sticky enough to adhere to the metal, but also allows them to move as necessary. (I used to work with high-vacuum systems for testing satellite systems and this is what everyone did. The requirements there were rather more severe than in a JH, but I think that adding rigid glue is making the possibility of a small leak all too likely).
