I hadn't planned on posting about this until last night when I learned what caused the incident. Last weekend I had an o-ring blow out at depth, we weren't very deep, only 30 ft but it did force me into a shared air ascent. The cause of the problem was I put the wrong o-ring on my yoke valve. I bought an o-ring kit which has many different types of o-rings in it and there are two different o-rings in that kit that will fit the yoke valve, and they are very very similar. Well I put the wrong one on and it blew. The wrong size o-ring is every so slightly too large but it fits in well enough. The correct o-ring goes in a little more easily and is slightly smaller than the other nearly identical o-ring. I hope someone else can learn from my mistake and avoid this. I plan on picking up a set of just yoke o-rings so I can avoid doing this again in the future.
