If the HP seat in your Aquarius is working with no IP creep, then it doesn't need to be replaced. When you do need to replace it, it is reversible. Just push it out of the piston and check the reverse side. If the other side of seat hasn't been used before, just flip it over and use the fresh side. Those seats last for years and really don't need to be changed at every service. The HP seat on the Aquarius I bought in 1978 is the original and has never been flipped. I've only encountered a couple Aquarius first stages that needed a new seat. As long as the IP locks and doesn't creep, the seat is still good to go.
The LP seat in the second stage is the same one that is used by Aqua-Lung for virtually all their second stages. Conshelf, Aquarius, Calypso and Titan second stages use the same LP seat.
PM me with your address and I can send you a set of O-rings. I may even have a HP seat lying around somewhere, if I can find it.
