Hose failure- A little concerned

[ChrisEdwards]

This hose failure happened to me as I was rinsing my gear. It is the LP BC inflator hose that came with my ScubaPro Knighthawk BC, that I purchased about a year ago.

It has about 25 dives on it. This has never been dropped or abuse,d from my knowledge, and has always travelled in a regulator bag, when not in use.

I'm just a bit surprised.

It really looks like someone or some thing got to it without your knowledge. Did you get any "help" from a boat hand just before you were using a rinse tank? They can be a little rough.

 

[ChrisEdwards]

I rinse off at home, usually a couple of hours after a dive.

I have three sets of gear to do normally, my Son, Daughter and mine, so I find it easier to just do it all at once at home, rather than with the hoards of folks getting off the boat.

It looks like it was over-tightened and just failed. Brutal, but at least it happened during the rinse time and not in dive time. Contact ScubaPro and maybe they will send you out a new one.. They are SUPER easy to self-install, but be careful of over-tightening...

I'm just curious as to how much time I would have had, had it happened under water.

I'm going to rent a full tank, connect it up and time how quickly it empties.

Agreed. But, a word of caution in this situation. First, you'll need an "easyout" to remove the broken piece still in the first stage. More importantly, there is risk that some fragments of metal have entered the first stage. Personally, I'd have the first stage checked out, even if you install the hose yourself.

That fitting has obviously been sheared off. It did not just happen - it had to have been broken by some force. Keeping a regulator in a bag does not necessarily protect against such damage. The good news is that a new hose is not all that expensive.

The point of failure shown is not effectec by tightening torque. I doubt if SP will cover it. A failure like that should be expected to empty a tank quite quickly. Under 2 minutes with a full S80. I'm pretty sure that damage ocurred between your last dive and the rinsing.

Or if the easy-out sounds to complicated, just use a wrench on the hex nut that is still in the port. Are we not all looking at the same picture?

An "easy-out" is not needed to get the fitting out and the break was not caused by "overtightening." The piece of fitting that connects to the regulator first stage is still threaded into the first stage. It can be removed with a wrench, just as it was installed. When a fitting fails because of overtightening, it fails at the threads, which are stripped. The threaded connection in the picture appears to be just fine. The end fitting itself failed at the connection with the hose. This is most likely the result of a sideways force having been applied to the hose near the connection. The damage would have been hidden by the hose protector. - One of the reasons I don't like hose protectors.
