PCP on other then air or co2?

[snowwalker]

OK shot springer for a long time, now need to get PCP (.25). Since I am new here I think I should be allow at least "one" dumb question so here it is.

Can I charge a PCP with a compressed gas other then air or CO2?

I know that I would have to regulate the pressure from my bottles, but I have that covered.

You can use Nitrogen (a good choice), or Argon (although the performance will be less than air).... or Helium.... On NO condition use Oxygen, any small remnant of any lubricant inside the gun can explode violently....

I was thinking of Nitrogen or helium, I can get them in tanks with a 6000 psi limit. The PCPs I have been looking at are 3000 PSI max so I will have to step it down. If I can't find a way then I'll just get a scuba Tank and use air for now... thanks.

You already know that filling from a 6000 psi tank into a 3000 psi gun is dangerous if not done carefully.... Most in that situation would either get the appropriate regulator (about $400).... or a "slow-fill" valve that has a restrictor upstream of the valve and gauge so that you have very fine control over the fill rate, and just watch the gauge like a hawk.... Most 4500 psi fill setups use the latter....

I can get the regulator off the shelf, and the bottle are already hanging around the shop. I am leaning toward the scuba Tank, as it will be easier and less headaches.

I've been using nitrogen in my HW110 from day one. When I researched filling, it became obvious that air was not an option. So I picked up a 6000 psi tank of nitrogen and the appropriate fittings. I know a regulator is recommended but they were fairly expensive , so I just picked up a T handled valve to help adjust the rate of fill and it works great. I am able to easily throttle the fill rate with the tank valve and there is no moisture to worry about.

You may have inadvertently avoided alot of issues- I did the same thing years ago, got a regulator and then tried to find proper connections to fit the regulator to a fill hose for the 1/4" QD connector on the rifles- never did sort it out, so that was $400.00 (at the time) in wasted regulator expense.
