No, that is just the cheap gauge. The YH is supposed to handle 4500 psi, and burst disk around 5k.
I've heard the burst disk lets go right around 4200-4500, so I've always been wary to go much more past 4100? I'd love to be able to put 4500 into my SCBA tanks but I don't hear a lot of good stories about people who do that.
Thank you JimNM. Any source for the correct gauge? Or will the cheap gauge be adequate?
What you have installed is the correct gauge. It's the same as mine. It works fine. Up to you if you want to drop the $$ on something else.
