almitywife:is this the one???
I had one that looked like that. It separated and partially extruded the o-ring after a couple of dives. I'd give it away, but I think they are dangerous. I'm using a 135 degree fixed swivel now on a 5' hose. Maybe I should get a longer hose.
O.K., I just noticed it sitting on my desk and it looks exactly the same, down to the bevels on the backs of the nuts.
