My hose exploded. Has anyone experienced this?

A first stage can supply full tank pressure it it fails and at some conditions the second may not be able to relieve fast enough to prevent a pressure build up in the hose and it will go kaboom.

Regulators, even todays unreliable plastic fantasitcs, rarely fail in this way unless they have been dorked up by some shop monkey with pliers and a hammer. I have seen new regulators fail however but genrrally not in this fashion.

It happened to me on a set of rental regs, shortly before getting ready to descend on my second dive.

I heard a BOOM...and felt like I bumped into something.

That's the day I decided to buy my own gear.....

There is a great deal of harm done to a scuba hose by oxidization, use of ntrox speeds this up.....

I was not aware nitrox was any more damaging to my equipment. What other parts are more prone to this damage. I am assuming the more dives done, the faster the damage is done.

the more exposure(dives done) and the % of O2 in the nitrox (36% EAN will do more damage than 28% EAN)

The HP swivel is one I always see as a Nitrox issue, it has a very high PPO2 as it is at 3000 psi, the orings turn to dust in a short time.
HO seats are also an issue

I'd get a new reg repair shop!!

Years ago the LP and HP ports were the same thread size. I believe this changed around 1990. Anyhow, I got those reversed on my 1977 regulator once, and it did not blow anything up. Yours must have seen real high pressure, like the 1st stage wasn't regulating.

I did this with my old Sherwood Blizzard. The LP hose on the HP port poped as soon as I opened the tank. The funny part was not the new hose poping, but the reaction by the Vietnam vet that was overseeing the check out dive we were going to do.

I have seen more complete HP seat failures than I can count. It doesn't take a hammer and pliers to do the damage; just an improperly molded HP soft seat. I remember that Apeks had a batch number of defective seats about four years ago. During that time, I saw dozens of comlete failures.

Like you said, when there is a complete HP seat failure, tank pressure is everywhere. In many cases, the initial slam of high pressure into the hose is all it takes to begin the hose failure.
