[CO2 Tank Problem]

Thank you all.  Looks like i wi be calling my nearest Airgas supplier.

[CO2 Tank Problem]

I was hoping someone may have had a similar problem and hopefully came to a resolution that did not involve buying a new CO2 tank.  Recently I purchased a CO2 kit that came with a refillable tank.  Now that the tank has run dry I am having a problem finding a place that can refill it.  The thread on the tank is CGA320 and I can only assume the painball places use 5/8-18 standard.  The problem is when i search for an adapter so they can refill my tank all I can find is the inverse of what I need since most people need to convert their 5/8-18 standard painball tank to a CGA320 solenoid valve. What I need is a female CGA320 to male 5/8-18 adapter.  Anyone have experience with this or can point me to the right product?
