Subject: Re: o-rings for poseidon cyclon 300

     That's consistent with what I learned from US Divers re: their 
     Conshelf series; that the O rings (and HP seat) need to replaced with 
     viton, but the original diaphragm can be used with oxygen.  I don't 
     understand the difference, but if it works, great!  As I indicated 
     before, I use an O2 cleaned conshelf with my O2, with viton o rings 
     and the new HP seat, and the original diaphragm.  I haven't barbecued 
     myself, however I can't help but flinch when I turn that valve...

. The diaphragm is the same as in the standard non-O2 cyclon 300, and that they 
never had any problems with this diaphragm  in the oxygen rebreather. They won't
sell parts to the end user, especially no parts which are used in the military 
unit.
