I have an MK2 that is used on a deco bottle and was looking for a source for the HP seat. The Scubapro O2 kit for this reg is stupid money, something like $60 so I would rather find another source. Viton O-rings are easy to come by but I just don't know about the seat. Yes the seat has been flipped once so that is not an option.
