Hey guys today I talk a little bit about diving with vintage Scuba tanks. I get questions from time to time about older tanks and whether they’re dangerous or not. Most aluminum Scuba tanks manufactured before 1989 were made with 6351 alloy that is known for developing SLC, or sustained load cracking. Its a condition that most dive shops do no want to deal with as it has potentially deadly consequences and should be a serious consideration when buying used Scuba tanks. A good read:

Cool look inside a tank don't think i would like the idea of a 1975 bomb on me back 🙂
I have two 80 AL's pre 90 that have been sitting full for 15 years…what do you recommend ? is the air usable ? I have 5 tanksgoing in , and would like to use these…. maybe run them at 2700 ??
my old steel tank has a coating since manufacturing. The Hydro test shop refuses to test it because of the coating. Based on your video the valve joint is the most dangerous area but not tank itself. correct?
Wait so it was manufactured in 93 but hydro tested in 89?
Video idea, knock the valve off the one under pressure and skip it across the lake. Mythbusters made a rig to do it u could make.
The only video of an exploding scuba tank i've found so far was a containment device demo. Are they too dangerous to film? <searches more> Apparently so. https://www.youtube.com/watch?v=W1nrFLj-SJ8
Those yellow double 50 alumininiums look REALLY familiar..
Hi whats your email address ?? Can i send u some pics of a tank i might be buying
I'll buy that full one right now if you want to sell. It will be great for my pcp air pellet shooter.
I dive with my all vintage tanks ,steel or AL..No problem..
Out of all the aluminum tanks I've have had tested, only 2 have failed the eddy current test. Both were Aluminum 50's. I've also had two steel tanks fail hydro. I would say at least for me with the number of tanks I have, actually more steel tanks have failed than aluminum if you look at the total number of aluminum vs steel tanks I have.
Have fun down south
