The design flaw is why you should always use two spanners when removing the hose. One to hold the heat exchanger and one to turn the hose fitting. When tightening the heat exchanger on do so with the diaphragm and cover off, press and hold the lever down onto the spindle to prevent it rotating as you tighten.
That's exact what I mean, if for a recommended torque for the heat exchanger of 45 inch-libs (5 Nm) I have to fix the spindle with my hand 'to prevent it rotating', this is a pretty unique design.
I don't know exact what you would have to do to make the spindle in a G250 or a Legend to rotate, but you would need a lot of force.
I know here are lots of APEKS fans in the forum and as I wrote before that I think that APEKS regulators are good regulators, but concerning this 'design aspect' I don't see any benefits for the users in comparison to similar 2nd stages. This little aspect is for me simply substandard, even if you could pretty easily avoid problems with it.
