D_B:Thanks for pointing out that burst disc consideration
just a note for anyone checking .. I think OMS has redesigned there manifolds and now have three O rings per side ... http://www.omsdive.com/valves.html
Except that the three O rings per side is nothing more than a marketing gimmick.
In any manifold it is the first O ring that that "seals" the thing and the second one does nothing unless the first one fails.
