Some advice/guidance please. I own a Titan LX Supreme (yoke). I'm considering purchasing a high pressure steel cylinder (3442 psi working pressure). The owner's manual for Titan LX Supreme indicates 3300 psi max for yoke. Would I still be able to use my regulator on a HP steel cylinder filled to its 3442 psi working pressure or am I risking damage to my 1st stage? How much wiggle room is there in the max pressure for a reg?
