Can it be safely done?
« on: June 21, 2017, 12:49:57 PM »
Guys

Being new to AR's, Co2/Hpa etc,
I have a question, that has been floating around my head.

I have 55+ cylinders of Co2 in the 88 & 90 gram sizes,
I have a Co2 bottle that came with the QB 79 package,
it is a 9oz and rated for 1800 psi.

Can some of these cylinders be used to fill this 9 oz, Co2 bottle,
meaning transferring the co2 into the bigger bottle?

If it can be done SAFELY, how would it be accomplished?

Or would it be better just to use each cylinder, as needed?

So far I have over 250+ shots from the first cyl, from my stock QB 22 caliber, and it still has co2 left,
I don't know how much co2 is left as there is no gauges to check etc.

For me, it's a 200 mile drive for any type of refilling Co2 or HPA,
I will have a hand pump for filling, to get by,
until the funds in the Rat Hole are enough to get a compressor for refilling etc.

Thoughts, suggestions?

Tia,
Don

Wished I could help you but I don't know anything about CO2.  Hopefully someone with some experience will chime in soon. The post hasn't got allot of views yet so give it a little more time. 

Sorry I couldn't help,

In the years I shot Paintball owned a 20# "Siphon" Co2 tank.  Setting normally it has a dip tube that when valve opened delivers LIQUID not gas. 
Co2 is calibrated within a containment vessel by WEIGHT not volume meaning that to safely fill empty Co2 cartridges they would need to be done on a scale to prevent overfilling and burst hazard if left in the sun or warm place once filled.
Pre-chilling of Cartridge or Bottle to be filled aids greatly in getting a good fill. ( Emptys in freezer prior to filling )

Now the $1000 question .... Are these empties designed to be refilled having any sort of internal check valve ?

Here is the info that is on the bottle and site info,
it's about all the info I can tell you about the bottle,
the 88/90 grm cylinders are JT, Brass Eagle etc, just normal cylinders,
from what little bit I know.

This is the co2 tank, I am thinking about filling,
With this AR package deal,
I also received a Valken brand name Co2, 9 oz bottle that states,
CO2 ONLY, NO HPA on it's label??
2-1/16" dia by 10" long, and has a 3K burst disc installed.

Here is the web site for this bottle,
http://www.valken.com/Tank-Valken-CO2-Alum-High-Pressure-DOT-TC-stamp-9oz

Here is the info that is stamped into this tank, I have no clue what it means etc,
if you can understand what the below info means, can you inform me, what it means,
it would be greatly appreciated. I am new to this stuff and AR's etc.

Top line = DOT - 3 (triangle?) L- 1800- P846120 . . M4625
Bottom line = TC - 3 ALM - 12 (triangle?) - 11 C 16 - 09 OZ CO2

The spelling in these marks ( ?) is my best guess, as these stamping are very hard to read,
and filled with paint etc.

I have advised to NOT USE HPA in this tank.


Thank you,
Don

Link shows as a dead end to a valid picture.
If the 9 oz bottles use a BRASS valve / ASA threaded attachment with a burst disk and check valve your good to go !!
Just do some searches on PAINT BALL Co2 tank filling parts / pieces and you should be fine.

As Motorhead stated, if they are Valkins, with their signature brass valve, they are refillable. Information is on their web site, even though the link you provided doesn't work.

I have an Omega compressor. If you're a fellow Guild member, and you pass through Roswell, NM, I'll fill your portable tank as a courtesy.

Guys
Sorry for the link mistake, redone it with a new one,
http://www.valken.com/Tank-Valken-CO2-Alum-High-Pressure-DOT-TC-stamp-9oz

What has me buggered is the 3k burst disc instead of a 1.5K,

Here is some info I got when I sent an email to them about the 3k burst disc,
Subject: RE: Co2 bottle PSI ratings
 
The tank service pressure is 1800psi.  The burst disc rating always higher. 
For CO2 tank, we use 3K burst disc. 
For 3000psi HPA tank, we use 5K burst disc and for 4500psi HPA tank, we use 7.5K burst disc. 
 
Here with the standard from ASTM.

Service pressure 1800 psi
Minimum Burst Disc Burst Pressure @ SAT 2700 PSI
Maximum Burst Disc Burst Pressure @ SAT 3000 PSI
Burst Disc Marking (Fig.1) 3K

Tia,
Don
