Question

On a dive have you ever blown an O-ring?

Answer 1

I have, and it can be a little scary, as the gas escapes at a pretty rapid rate. My personal note is to always use Viton o rings, and I replace them every year, or when they show signs of wear (whichever comes first). When I am on a trip, I take that extra minute do give it a good check!

Answer 2

I have not, but now that you say that I may have to add some more to my kit, think the ones in there are a few years old!
