I have a US Divers Conshelf SEA regulator, and Conshelf Octopus, which I bought new in Sept of 1992. It's been stored a LONG time, but I just got it out and took it to my local dive shop. They checked it out and said it work fine!

My question is, what are the service kits (stage 1 and stage 2) that would go with this regulator and octopus?

Thanks!!
