Fittings for large metal AIR tank one used for breathing air.

first you do not describe it properly and then again come at me like you already know it all... I am done... good luck...

I changed the post to AIR tank, I meant it looked like an acetylene tank.   Its not,  I changed the heading to prevent further confusion.   I did not come at you like I know it all, just letting you know that there was not an issue filling it, they are the ones giving it to me and already said they would fill it.   From my point of view was "how does he know if these people would fill it or not"   But I think you were coming from the view point of "If its a real acetylene tank no one will fill that with air.

So no hard feelings please, just confusion on what type of tank it really was.

If I had the chance I know what I would do...
I'd set up my own cascade system and feed an Altaros booster at 125 psi in and 4500 psi out. You could probably supply the Altaros until they were down to around 500 psi. I would use a carbon fiber 4500 psi tank as a reservoir. Dry air in, dry air out.
Might cost a bit initially but think of the savings and convenience.

You are a Mad Scientist, I like that!

I could get 4 of them.   Have to ask if all the cascade lines are included.    One is scary enough, they can weight from 150 to 290 depending on size and I am not sure on the size yet.

Just to expand a bit here...
At $72 a year lease and $18 replace/refill delivered including all inspections, regs and gauges. ( if included ) I'm pretty sure one guy using from it would be very happy for quite some time.

I think that is a very good deal you have there.   They test, fill, deliver and you just shoot.  I like it.   Saves on gas and driving time.

For the record my little sis became a firefighter in 1980... was on the bomb squad and then became a fire investigator... in a major city... My youngest daughter is a certified welder and I have learned from others over the years by staying as humble as possible...

What I was trying to get to is you need to know exactly what tanks they are and how old even their position in the chain and how exactly they where cared for before you know if they are worth it...and that was after you cleared up describing them as being acetylene tanks... It all gave me a feeling of a laissez faire attitude about safety...

I have heard of tanks exploding but not here yet... or even valves getting knocked off..but watching the full auto BB vid is the kind of thing that I think is reckless and prevalent... I just does seem like a matter of time...wish there was a free training course for everyone and enough humility to go thru it for many here... I would take it if I was getting tanks... and I do know just a bit...

I feel it would be wrong to advise anything before knowing exactly what the tanks are and more about them... could guess instead of knowing tho... not my life or even near me or my loved ones...

So yeah your tone could be much much more about learning and trying to understand others points... tank corrosion and transport are  my main worries...

but hey your tone towards me makes me  think I am dumb or something...so I feel dumb posting this...

Hey I liked that link you gave me, lots of good information I did not know on these tanks. 

My uncle was a fire chief in Chicago in charge of  3 stations also have cousins and nephews that are firefighters.
But I don't know anything about their tanks or equipment.   So I appreciate the information.   

This tank "if I get it" won't be moved much, only once per year.   From the information you gave it does sound like they need hydro if you move them.     I think the scuba shop will use for breathing air and use their own compressors.

I do appreciate the safety information, I don't want to get blown up.   I'll have to check when they were last hydroed.   Just don't have enough information on them yet.

I may have missed it but, why are they getting rid of these tanks in the first place?

Your guess is as good as mine on that.   I doubt because they are ready to blow up or the scuba shop would not want them.

I will find out soon.

[avator]

LOL..... I wasn't suggesting that at all.... just curious.

[KnifeMaker]

Wow!!!

Must be that time of month for many here.  With all the expert advice, I find it odd that no one ask the simple question--What color code are they?

And Fire Dept's are well versed and tested on filling. No way they would be, in the recent past use "ANYTHING" but high pressure AIR tanks for cascade, nor would they offer to give, much less offer to fill anything else. If they did, they would fail State and Dot certification with the first inspection.

This should have been obvious from the start. Particularly from the Experts!  And Yes, I am an X LEO/Firefighter. 

This post has far too much hateful post in it to pass muster. Just because the man doesn't know bottle colors, should not the Experts at least know enough to ask the proper questions before running someone else down? 

I find this thread disappointing, and mean spirited.

I think rather than giving advice coming from an mixture of ignorance and arrogance, or simply trying to be helpful, perhaps a simple suggestion would be to look at the markings on the bottles, and color, and ask both the designated station Safety officer, and also to take the info to the local, or nearest commercial/officially certified fill station, and get the true info rather than wild speculation.

It is not mean spirtited to suggest he learn what he is doing before he starts messing with a large volume of 4500 psi....Me I did not claim to be an expert in fact I said I know  A little... must be your time eh...

[K.O.]

oops 6000 psi my admitted concentration probs showing again...

Yea I don't know a thing about those bottles and I can't get over there for a few days to check it out.    I don't know if they are safer than carbon fiber, or if they have to be hydroed etc.    My concern was just over the sheer weight of them.    I did see one at the PCP gun shop but he had his own compressor.   He had it out next to the range inside and well he did not seem to concerned that it would blow up so that part did not really enter my my mind.    Then a day later I find I can get a similar tank for free.   Thought hmm maybe I can find out more on the forum.     

I'll just ask them when I have time, they will have all the answers.
