I've a new Aqualung Legend Regulator. On my 1st stage it is stamped 3000 psi. I'm planning on purchasing a HP steel tank. The psi is 3442, will this harm my 1st Stage? Thanks for any help!

jonahfab:High pressure tanks all of din valves on them, thats why they can be rated usually to 3500 psi. Your legend's rating of 3000 psi is because of the yoke. To use the high pressure tanks you will need to convert your reg over to a din style connection. The din adapters are relatively cheap and easy to install, or just take it to your LDS and let them set you up. I converted over my apek and have never looked back.
Ontario Diver:You already know the anwer.
You have a 3000 PSI rated yoke and you are asking if you can put it on a tank holding 3442 PSI.
It is similar to putting 4000 psi of air in your 3442 psi tank.
jhelmuth:If you say so...
All yokes are rated to 3000 PSI - its a function of the o-ring seal (not the strength of the yoke).
jhelmuth:. If you tell your reg tech that you are using HP tanks, he should be able to tell you if he can make and mods to the internal o-rings (maybe even the HP seat) to make it more reliable. .
LUBOLD8431:Not true. Some yokes are rated to 3500 psi (Oceanic for example, however DOT may have just changed that ruling). It has little to do with the oring seal.
