HP Hoses Blown . . .

[Bigbella]

I have had two of those thinner, “Kevlar” HP hoses blow, in the last couple of months — both of which showed no prior or obvious signs of wear and tear; and were all less than a year old. Has anyone else had these issues? Conventional HP hoses, in my experience, have typically lasted for several years.

This morning, one managed to blow in a couple of spots; and, damn, when they go, they really go . . .

Scary! I can't tell from the picture, that's not a flex hose, is it? I have flex hoses for the LP but I think I have a traditional rubber one for the HP. Were you underwater at the time?

No, it's not the braided variety -- it was simply referred to, in a German catalogue, as a 300 bar "Kevlar Schlauch," or "hose."

Thankfully, it happened between dives, upon pressurization of a second tank, and the rapid loss of about 400 psi, before the valve was closed. A spare blind screw; some startled beachgoers, and some incidental swearing salvaged the dive . . .

Wow, very disappointing that a 300 bar hose would fail in a year. I assume you're not running it much above 238 bar. Thank goodness you weren't at depth, but even a small leak is startlingly loud.
