I'm going to throw this out there in order to understand why??
I have a small Argon gas cylinder that I no longer use. I went over all the numbers on the cylinder and I believe it is tested for 2015psi.
The weight of this steel tank appears to indicate that it will hold much more psi then marked. It is a small #1 size sold by TSC under the Throughbred brand name.
This would be a great tank to use to refill my Outlaw at my home shooting range. The price of a "Guppy" tank is way to high for me.
I wonder if someone tests these tanks for a small fee?
-
Are you thinking about running for a Darwin award? If the cylinder is rated for2015 psi, don't try to push it to a higher pressure!!!! There's also the issue of different fittings.

LOL... I agree... don't fill past stated cap. I have a nice little (red) extinguisher tank. It's cap. is 1800 psi. Wouldn't even consider exceeding it.
-
I don't plan on exceeding the stamped psi unless it was approved by a testing facility or the manufacturer. Since I didn't have any luck there I have it up for sale right now.
-
Are you sure 2015 isn't the hydro test date?
typically industrial gases are nice round numbers.
Argon cylinders have a nominal fill capacity of 2000 - 2250 psi
-
Well I am not sure, here are the numbers that are printed on the cyl.

thanks for asking Hoosier Daddy
Well Mr Doug Wall I don't know what a Darwin award is. I have learned one thing by asking questions on this forum, DON'T.
Good Bye

Hello Wade, that was a friendly joke about the Darwin award, do check out the Darwin awards, it's fascinating. High pressure scares me, but I am cheap. I have a scuba tank with adaptor for my airgun. It's 3000 psi.
I saw a high pressure tank in the bargain gate. Perhaps you can find a welder who needs an argon tank. Maybe you can recover some of the value from your tank to apply towards the one that you need. I think that these tanks are color coded, I don't feel comfortable with mislabeled tanks.
Good luck.

Is it possible to use an SCBA tank rated at 4500 psi to fill my PCP?
They list the size by 30 min or 60 min, anyway to determine what cu ft that is?
Very good prices on ebay with current hydro.
-
Yes you can. But be more concerned with the manufacture date. Scba cylinders are only good for 15 years from the manufacture date. It doesn't matter if the hydro date goes beyond the end of life of the cylinder. No scuba shop or other fill place will touch after the 15 years are up.
30 minute cylinder = 45 cu ft
45 minute cylinder = 66 cu ft
60 minute cylinder = 88 cu ft
Thanks,
Taso

You can get a regulator for the SCBA tank. Set the regulated pressure for the rifle that you have. Some use 1000, some 2000, some from 3000, and some use 3600 psi. If you don't use a regulator then you must be very careful that you don't overfill your rifle.
-
Thanks Guys,
OK I should look for a tank that has a current hydro, and that has several years of life left (not 15 years old) .
The 30 min size should work for filling my DAQ Outlaw.
I will be filling the tank with my Yong Heng compressor so it should never have go to a place for filling.
I guess I will have to wait until I get the tank to determine what fittings I need to fill the tank.
-
Wade,
From what I've read it is not recommended to fill a 4500 psi tank with the Yong Heng compressors. They aren't designed to handle that type of stress. It's seems they are better utilized to fill rifles directly. A $500 Shoebox compressor can fill scba cylinders to 4500 psi no problem.

I just went thru this, here is some info that may help you,
There are 2 basic fittings for SCBA tanks, they are called CGA 346 or 347,
both come in either wrench or hand tighten models.
The 346 has a shorter nipple/probe that fit the tank fill nozzle, = 2-1/2" long,
the 347 has a longer nipple/probe at 3" long.
I have 2-347 and the hose hangs off/out from the tank sides about 2 to 2 1/2", depending on tank size.
Here is the 347 I got, all SS and works very well, gauge seems accurate when compared with my accurate test gauge.

Wade and Don,
CGA 346 is only rated to 3000 psi. CGA 347 is rated to at least 4500 psi. I may have jumped the gun on this. I'm doing more research. Sorry.
Thanks,
Taso
-
Ok, CGA 346 is only rated to 3000 psi. CGA 347 is the fitting you need for the majority of firefighter 4500 psi scba tanks.
Sorry for the confusion.

If you want to use one of those big ole tanks then I suggest you get a booster pump like the Altaros and feed it with that tank. Regulate the input to the booster and you'll be set up much like the local FD.
-
Thanks Guys, that info will help a lot.
I read somewhere that some people are trying to get the 15 year life of an scba cylinder changed to 30 years.
-
Have you looked at the "airtanksfotsale" website?
It's through the vendor gate. I think that there could be other vendors linked from the GTA.

This is true.

That's true, but I think it costs about $300 to get the testing and certification done (only one company doing it), and you have to get it retested by them periodically.

It's tough on small town Fire Departments to come up with that kind of money to keep their equipment up to date. If they re-hydro and it passes but they have to scrap it because it's 15 years old.
Imagine the cost for just 10 bottles for a FD that works on a Volunteer basis with limited funds, asking for donations with a boot at a stoplight.... and people look the other way.
Doubling the lifetime would certainly help them out as long as it is safe.
-
Yes I did see that site and the $300.00 cost, I have to keep reading and decide which tank to purchase. My Yong Heng can fill my LA Outlaw for now, it will just be a lot of trips from my shooting bench to the work shop and back.
A small CF or SCBA tank that I could fill with the Yong Heng to say 4000 psi should give me 4 or 5 fills for the Outlaw.
Thanks for the info.
-
Wade.... not to be the neigh sayer here but...
It's one thing to fill a gun to 3k, or even 4.5k for that matter, with a YH. It's done in a matter of minutes. It's a completely different beast to fill even a small (30 minute) scba tank to 4k or 4.5k. You're now talking about 20 minutes or so of that little compressor pushing those kinds of pressures. If it were me, I think I would stick to filling guns and stop at the paintball field or FD to have my tank filled for a road trip.
-
Good advice Avator,
I was worried about running the YH for an extended period of time. I will forget about trying to fill a tank myself for the time being. I will still check on getting a small tank and look for a fill station in my area. I live in the hills of Northern Pa. it will probably take at least an hour drive in any direction to find a fill station.
Thanks

FWIW,
There is 5 and 10 minute survival CF tanks also, (unknown CF size), I have seen several for sale, kinda expensive, IMHO, they might be a help to you,
I have been looking at them, as a small tethered tank for sniping the starlings etc, from my starling shooting hole, inside the house,
instead of using the bigger CF tanks.

Don,
This is interesting. Do you have any links? Do they use the CGA 347 fitting? If the price is reasonable I'd rather tether off this versus my 30 minute cylinder.
Thanks,

Let me dig up some info on them,
I know the SCUBA diver also have, what they call "PONY" tanks,
that provide a few extra minutes of air for an emergency etc.
Here is one type of the PONY tanks,
