Anyone got a 6000psi nitrogen bottle from Airgas lately?

[tworst]

I recently decided to get a 4600 CF tank but wanted to make sure I had a place to fill it first.  So, I contacted the local diving shop to inquire.  Get this, they will NOT fill CF tanks.  Why?  There insurance will not cover it!  I couldn't believe it.  I have seen so many videos with people using CF tanks, where in the world do they get them filled if you can't even get it done at a dive shop?

Now, I have contacted 3 fire departments, paint ball facility, Dick's sporting goods, Airgas and dive shop and nobody will fill a carbon fiber tank.  The best I can do is the dive shop, 4000 psi steel tanks.

 Try Placing a Want to buy add for a Freedom or Freedom 8 Compressor on the forums there is always someone looking or thinking about selling so they can upgrade their equipment. Then you can fill your tank at home at your leisure'

Wow.  I found several dive shops that would fill it but they could only get up to 4k psi.  I couldn't find a firehouse, but was directed to a company that fill the bottles for some fire departments.  They happily fill mines for about $12.  I took 2 today and they filled both for $12.

I don't have the actual numbers but for nitrogen to be liquid at normal room temperatures the pressure is probably easily 6000 psi that is why it is called a refrigerated liquid gas.

Excuse my ignorance, but I still don't get how it could be used.  Are you saying put it in a cylinder in liquid form and let it convert to gas in the cylinder or put it in the gun as liquid and let it convert to gas?

  When you regulate the nitrogen down to useable pressure ie: 3000 to 4500 psi it will be in a gaseous state at those pressures. You will normally want something lighter for portability than the 6000 psi nitrogen tank which is quite heavy along with the pressure reducing regulator so a more portable cf tank makes sense as a source for compressed gas to operate your rifle

I have a 305 cu ft cyl at 6000psi. Joe set me up with a regulator so I can teather or fill my tiger shark. Nitrogen is the way to go clean dry, guns should last a long time!

I fill my tiger shark carbon tank from the nitrogen tank. It is 71 cuft and about 20 lbs. many fills!

You and I have the same setup. I have the tiger shark CF tank as well and fill mine with my 444cf 6000psi nitrogen tank. However, I got my fill assembly from Airhog.

  If the 6000 psi nitrogen is available for a reasonable cost it is the better way to go no moving parts to break and no maintenance for the HPA compressor so less peripheral equipment

     Just put a 6K tank in the garage today. Called every welding supply in South Jersey. Fills ran from $120.00 to $180.00. One shop told me 30 dollars a fill. When I got there they said they quoted me on a 3K bottle. Only one shop stocked the 6K bottles. All others needed a 1 week turnaround time. Received the fill station from Joe Brancato last week. Good to go now. Next time we have a shoot there will be plenty of air. Now if I could only talk that palone guy into a PCP.

  Be patient I will bring the RS II .22 , AA S510 .177 and the Daystate Huntsman Regal XL .25 and I'm sure Grady will bring plenty of shark bait as well

Just refilled here in WI from Welders Supply, same $56 as always ...

How do you unsal and regulate 4500-5000 psi outflows?

I called Matheson Gas in Council Bluffs, IA.

$383 for a 300 cubic foot tank, and $35 for swaps. First fill free, no rentals.

I went with a Yong Heng/SCBA tank, but I thought I'd put this info out there for reference. If I was going to do it all over again, I might have gone the nitro route with a guppy tank for portability.

edit - I forgot to ask if that was for 3k or 6k nitrogen.

You need a regulator. Mine is a Matheson high pressure dual gauge regulator on mine. All my fittings are Micro-bore hoses and SS 1/8" NPT Foster quick connect fittings. Check out my other thread were I'm documenting my set-up to use a cheap YH compressor as a booster from my nitrogen tank once it drops pressure.

Seems Air Gas and Fasten All here are bound and determined to Not do business with mostlyh anyone. AirGas, either will not do business with anyone without a credit application. (Yet you pay up front) and Fastenall has closed its doors to any and all who do not have an open account billing. NO Non Contractors allowed, Perion. hey!, This is how we built America?


Now that I am Retired Medically, I no longer have a Tax #. So I'm screwed either place. GRRRRR!!!


If Mcmaster carr or the o ring store follows suite, we are all screwed. Nothing left but full retail prices. No bulk, no discount. Priches on such thing will go up in many cases 1000 or more percent. Double GRRRRR!!
