Co2 bottle filling

Does anyone have any links to a set up to fill your own bottles? I have a couple people locally that run bottles and would like to find a turn key set up that I could buy to get a mother bottle from a welding shop and fill all of our bottles for the local guys. Also some filling instructions would be great. Want to fill them correctly and I have seen the set ups at local places that don’t look like they are very involved and could be affordable. Thanks!

I bought 2 cga320 nut and nipple assemblies, 2 npt to an adapters and a 2ft crimped an line. As for filling I know it's not the proper way but I don't even take mine out of the cars I just open the bottle and crack the valve on the mother bottle 3-4 times. Not sure what I actually get for volume but I get 1000-1500 psi.

don't have mother bottle setup YET. I went to local paintball store and had mine filled for 4 bucks. Cheap but still PIA.

I am working on a set up like A.R.P sated and appreciate the info on nut PN.

30 seconds later update.Just found a adapter on ebay for 13 bucks. Punch in cga 320 adapter. Alllow direct connection to argon bottle or a regulator could be used I guess.

Guy at paint ball store said he could get more info a chilled bottle.

My buddy gave me a full 20lb co2 bottle. I just make sure it's warm, I freeze my small one. I have two bottle nuts, one for each, and a hose. I just attach the two and open the valves, mother bottle first then small one. Wait for the flow to stop then close both valves and disconnect hose. Works like a champ.

Simple – Go to a beverage store that fills co2 tanks for fountain beverages. Buy a 20 lb bottle with a bottom pick up – Then go to a welding store and get an adapter from the co2 beverage bottle to the car bottle (make sure you get extra gaskets) – simple, easy, and you are set for a few years and you can fill a bottle in about 20 seconds. Cheap also.

Been using this method for 20+ years. C02 is very cheap at a welding supply store. A big bottle seems like it lasts forever. Hardest part is finding the transfer hose (and not losing the gasket when other people use it)

I use a -4 Teflon nitrous hose I had laying around. It's rated at 10,000 psi so it should be good!

I did the same, a couple of cga320 fittings, a 3000 psi hydraulic hose from TSC and a 20 lb bottle with a dip tube.

here's the thing about the 20 lb bottle, it has the be hydro tested every 5 years and the co2 lasted 6 years before i had to spend another $20 to fill it up.

PS if your going to buy a tank, get a few "Perma-Seals" the best thing ever!

this is what i use, large mother bottle with dip tube.

i dont bother to freeze the small bottle, i will put alittle co2 into the small bottle, close the valve at the mother bottle, vent out the bottom valve and it will cool the small bottle quick, close the bottom valve, open the mother bottle valve and fill

I ran a bottle for years and was always against installing a K&R onboard compressor because filling the bottles was not a big deal to me. Finally broke down and installed one after switching to TD and to be honest, its nice having 1 less thing to worry about and glad I did plus have used it more than a few times to top off the tires in the lanes after a delay. Just food for thought.
