    First off before my question I've seen a lot of post/searching also about Nitrogen.  Maybe a sub category would be beneficial.

     

    My question is what fitting, hoses, or regulators are needed to fill from a Nitrogen tank?  I seen some folks filling straight from a tank, this makes me a little nervous.  I understand it's like filling from your scuba tank to the rifle but you should of seen the pile of kittens I had the first time I cracked my scuba tank to fill the rifle.

     

    Any photo's thoughts or set ups would be great.  Just thought of something else if filling straight from tank to tank you'll need a bleeder valve also right.  I'd hate to have hose slap me in the face.  It'd probably be worse than a bad night at the bar.

     

    Some folks might be wondering why I going with the nitrogen set up.  As always cost.  At this point in time I can not afford afford the out of pocket expense of a compressor.  I've seen to many horror stories about the Chinese compressors.  I'd buy one, like I'd own a Ford.  Something I might have to work on every time I started it.  With nitrogen in a tank it's dry nothing to go wrong, I'm still shooting and saving some money for a reliable air compressor and a dryer.

    Oh side note I live in the part of the country where to actually own a bottle is unheard of with the gas suppliers.  Our gas our way.  I've got propane tanks for my grill nobody will touch.

    Thanks

    Very simple. Contact Joe Brancato at Airtanksforsale and he will sell you the complete setup.All you need to give him is the code number for the type of tank and pressure and that you get from the vendor thatvsels the tank.

    This is exactly what you need for a 4500 psi nitrogen tank and this was supplied to me by Joe Brancato.

    I personally like a regulator between the 6000 PSI tank and the 4500 PSI SCBA tank.

    If filling a gun straight from any tank takes a lot of care to be sure you don't over fill the gun.

    I agree Joe is a great source for solid information/ assistance.

    If you are going the nitrogen tank route its worth getting a 6000 PSI tank and the appropriate connectors and regulators. For most PCPs once a tank drops below 3000 PSI its 'dead air' and no longer useful for filling PCPs. A 6000 PSI tank will give you lots more fills than 4500.

    Yep, talk to Joe and he'll set you up. You can get a regulated valve (approx $479) or an unregulated valve (approx. $189) I've got the unregulated one and have zero problems filling my 97 cu ft tank from the 6000psi nitrogen tank. If filling a rifle straight from a 6000psi nitrogen tank, it would be a good idea to have the regulated valve.

    I would reccomend looking into getting a breathing air cascade bottle and then getting it filled at scuba shop. Then you could find a place that just charges you to top it off.

    I looked into getting a 6,000 psi nitrogen bottle, but found a lot of negatives;  first, they weigh a ton…you can not lift one by yourself; they have inch thick steel walls.  probably over 300-400 pounds.  second, you have to rent/lease them, at least in my state and get them refilled on a contracted schedule…you can not buy/own them like my Argon, CO2 or Oxygen bottles and if you could, they would cost more than a compressor..  So I bought a 300$ Yong Heng compressor and a cheap dryer… The system will pay for itself on my 6th bottle fill, if I count the fuel cost for the trips to the dive shop…that's probably less than a years use.  So after that, it's free and convenient 4500 psi air, not to mention that I can fill free-to-dirt cheap out-of-date bottles if I want, and can fill my friends bottles free, which should make me somewhat popular….theoretically:-)
