In all my years of diving and servicing regulators I have never seen that happen! I sure most of us have been in dive situations where that would have put the old heart rate into the danger zone.

I can imagine the possible cause being the diaphragm retaining device not being sufficiently tightened. Maybe would hold for a good while, but after the rubber was compressed for a long time it just may not have been enough to hold it in place against the intermediate pressure it confined. I suppose a flaw in the internal reinforcing layer could also cause one to split with similar results. Or maybe that diaphragm series did not even have reinforcement in the rubber. I seem to remember them being a little softer that some. Could be mixed up about that.
The older I get the better I was.

Interesting that both incidents discussed involved Zeagle regulators.
