Ever seen an O-Ring blow?

[mannydib]

I had the o-ring on the hp hose go on me at the begining of a dive at around 20'.
I heard a roaring behind my head that I knew couldnt be the boat.
I was pretty calm about going up, inflating my wing enough to be positive.
When I hit the cloud of bubbles that had formed above me my vis dropped to near nothing and i remember feeling alittle panicky wondering how far I was from the surface.

Maybe I am doing something wrong but I have never had a O ring blow in 30 years.
Or it could be I maintain my own equiptment.

Yeah happened to a friend of mine. Woke up choking while doing a long deco. But then I have seen him take unusually long blinks while driving too. Scary stuff.

Must be jon-lined to the upline...?

i guess they dont make the gear like they used to!

i was actually at fault in the above mentioned incident.
i had re-attached the hp hose and only hand tightened it.
this happened 6 months later, so i imagine it was lose enough to unscrew enough to let the o-ring extrude. now i know better!

I've never had one blow either, in my barely wet scuba experience time compared to yours. Your statement is comforting.

Has anyone blown a well maintained O ring known to be in good condition, inspected before the dive, and properly connected, if applicable?

I've seen quite a few in rental tanks, seems like the high traffic these tanks receive wears them faster than those of owned tanks.

I make a note to replace the Oring on rental tanks every time I use them, cost next to nothing and saves a dive.

It's more expensive to sit out or abort a dive than to take a few seconds and replace the rental Oring.

Not me - statistically it can happen, but as a practical factor, it would be most rare.
