Anyone know if the carbon fiber bottle has a shorter lifespan than the metal one? Just wondering if I can expect a long safe lifespan out of it. Couldn't find anything on the internet. Figured some of you guys might know.
Life span of Texan CF tank vs standard metal version

It probably depends on the process used for the carbon fiber. If they used prepress CF sheeting that is thermally set, it will have a much longer life than carbon fiber set with resin/catalyst type. I have no idea how you would find out though.
I would bet that you could find someone knowledgeable about such things at a dive shop.

As long as both receive only dry air I would see no difference. Corrosion would be the death for each. Fatigue is not the failure mode from what I have seen.

One cant out live the majority of HPA vessels.
The internet fear instilled in many is
.
One cant find 5 legit failures in the last 5yrs amongest millions of used SCBA vessels.
7000psi just never seems to register in folks minds.
Only the extremely rare "possible" fear factor.
Sounds familiar.......

The Specified lifetime is 15 years for carbon fiber wound aluminum tanks. Are there some in service longer. Likely. How many people have their CF bottle gun tank hydro tested every 3 to 5 years? Few I would guess.

I am not really too afraid if it. I was just wondering if the metal bottle would last longer. I have an excellent set up to make clean dry air so that's not a problem.

CF does not fatigue like metals. A long time ago I use to repair simi trailers. I use to see fatigue cracks all over the roofs of trailers from flexing. I spent 30+ years working with CF for aerospace. Did a cycling test on some MTB handlebars that one of the engineers was developing for Easton. They tested it in a test machine that flexed the bar in up and down cycle. The machine broke at a million and a half cycles but the bars were just fine. In fact I installed them on my mountain bike and they're still on it. My middle daughter rides the bike now. That was back in 1994.
