Once things are back together, dry fire a couple of dozen shots with no barrel on the marker (just to keep oil out of the barrel) to distribute the oil.

Do the oil-in-the-ASA thing after every case of paint, or so, through the marker.

If it is true that FA22 sometimes fills his HPA tank with oxygen, we will be reading about him in the Darwin Awards one of these days. Cylinders that are used for high pressure oxygen have to be to be specifically designated for that service. There is just a bit of extra effort to make sure there is no oil or grease remaining from the manufacturing process.

I own several welding gas cylinders. If one needs to, an oxygen cylinder can be converted to hold other gasses. But, no other cylinder that has ever been filled with any other gas can be converted to an oxygen cylinder. There is just too much possibility that the tank could have become contaminated with oil, grease or other flammable material. The tank cannot be cleaned well enough to be returned to oxygen service, a federal regulatory law.

If there is oil, even the smallest amount, inside a cylinder being filled with pressurized oxygen spontaneous combustion will occur converting the bottle into a shrapnel bomb. A cylinder that has been filled several times with compressed air may well have become contaminated with oil residue from the compressor. Not likely, but paintball field compressors are not maintained as well as a scuba shop compressor is.

When at home, testing changes I have made in my marker, I will sometimes fill my tank from my argon cylinder (a non-flammable and non-combustion supporting gas). Filling with oxygen is like playing Russian Roulette  with a bullets in all chambers. Deadly dangerous and extremely foolhardy.

As for putting oil in the ASA: If you are using compressed air or nitrogen (sometimes you'll actually find a field using nitrogen) there is no danger  created by getting oil contamination in the tank. In fact the regulator used in the neck valves on these tanks need lubrication just like the secondary regulators need on occasion. I actually put a drop or two of oil in the quick connect fitting before attaching the hose to fill my tank. If your tank valve leaks, then just like the marker's power valve, that drop or two of oil may fix it.

Now another bit of information that FA22 doesn't appear to have. The pin valves on HPA tanks are one way valves. You cannot fill the bottle through the valve, like you do on a CO2 bottle, even if you wanted to. Since there is no back flow through the HPA valve, oil in the ASA cannot get pushed back into the tank. And as I said, with compressed air or nitrogen, even if there were oil back flow, it would make no difference.

i wanna see you shoot 36 with paint and then watch u clean your gun for 30 min

Now on the other hand,  Yes using o2 is like asking for problem....but when used in the proper fashion such as making sure no oil is present and filling slowly to avoid heat, then you're fine.

You said it yourself.

.  I love o2 because you can get much higher volumes of it at lower pressures, it is dead silent to shoot with it.  Put some in a stock 98c and the gun sounded like it had a silencer. (then again regulated down a little)  And o2 can get back into the reg of the tank.  Get this, if stuff can come out of the tank, stuff can go in at the same time.  And yes i know of one way valves and such.  My tank is a dye which of course for the technical record, is a shrader valve.  Take this example.  A bike tire (which uses these valves) You push the pin in while there is gas in it.  What happens?  Air comes out.  Just so happens that you fill it from the same port.  Air goes both ways simultaneously.

You have no clue, first off O2 is heaver than air , air=1 , O2=1.1, Nitrogen=.8..... Now what weighs more a ton of feathers or a ton of bricks. It takes the work of a compressed gas , de-compressing to shoot a paintball . if it takes 500psi of HPA to move a paintball in specific marker at a specific velocity , it will take the same using the very dangerous O2 . Your examples above are wrong.

Your advocacy of O2 is ludicrous, and so dangerous I wouldn't let you play on any paintball field and if anyone knows him, turn him in for your safety and his.

As for layout of my marker, the placement of the Volumizer required an extended fitting to reach through to the power valve. The "T" fitting was only slightly longer and it is aluminum.  I actually like the blue anodized color of the Earl's racing fittings.

You will note that my pressure gauge is installed in the bottom of the Volumizer in a drilled and tapped hole. On my son's 98C, we did drill and tap a hole in the side of the chamber for the hose connection.(old picture)

Back to this oxygen thing. I have been a welder, machinist, welding supply salesman, college welding instructor and have worked in gas cylinder filling facilities. If you are actually filling a paintball HPA tank with oxygen, you are walking the ragged edge of the potential for serious injury.

Now, as to the absurd statement that oxygen is heavier and thus quieter to shoot than compressed air is about a bogus as it gets. Air is composed of about 80% nitrogen and 20% oxygen. On the Periodic chart Ni and O are virtually next to each other (atomic weight). The argon that I use on occasion for testing is much heavier than either and there is no difference in the loudness of the report from the marker. You are advocating, using oxygen, something that is potentially an extreme danger for a player to do and you are making it even more enticing by stating that it has some advantage over compressed air or nitrogen.

just a little correction: N=Nitrogen. Ni=Nickel

Sorry! I doubt if that typo would have been detected by or made any difference to FA22. But, I do try to keep it accurate, thank you!
