Questions and Answers for ScubaPro MK25 / S600 Black Tech DIN Regulator System:
Im looking for Regulators that are tested to over 4500PSI(300BAR) because im looking to do 88CU FT tanks and i need a regulator set which can handle this. I have yet to see a regulator listing it self up to this PSI.

Technically speaking the cubic foot rating of your tank has no bearing what so ever on the psi rating of your 1st stage. That in mind, there are currently no regulators specifically tested and labeled for that PSI. Basically they all test them that high but none will specifically label it for use. Unfortunately it's a lawsuit happy world and we're all too aware of that in Scuba.
