I have experienced this problem a couple of times from different manufacturers, so I do not think it is brand specific.
This involves a DIN nipple. There is the large 112 oring on the valve side and frequently, but not always a smaller oring 008 to 011 or so on the opposite end. The smaller oring seals against the regulator body.
What I have seen a couple of times is a malfunction where the smaller sealing oring somehow becomes deformed and enters the regulator HP area.
Sometimes this interfers with the internal components causing the regulator to fail in some manner. In one case, this happened to a new first stage that worked properly for a week and then suddenly started discharging hp air thru the low pressure ports. The oring was found in the regulator body preventing the diaphram regulator from functioning properly.
Just recently, I encountered a similar issue with a piston regulator. Only this time the malfunction was that the dislodged oring inside the regulator body blocked one of the high pressure ports from receiving air. This regulator had been functioning perfectly for 9 months prior to the problem.
I am curious, if anyone else has ever seen this?
