So this is what I have, but I have to manually loosen the large brass but every time I disconnect my disco. I'd like a regulator with a built in bleed. What do I need to get and how would it be set up? I'm clueless, so don't worry about talking down to me, literally any information would be helpful. Thanks!

before we get to what it needs, please tell us what kind of tank that is ?
PLEASE TELL ME that is NOT an oxygen bottle for a welding setup !
if it is, do NOT use it.

Ha! That's exactly what it is, filled with air to 4500psi. Again, ignorant here. Why shouldn't I use it?

My steel oxygen tank gets filled to 2250psi, and (without hitting the shop to check the cylinder markings) I'm guessing its maximum working pressure to be close to that mark. You can confirm your tank's rating by checking its markings online, and if it is similar to mine a 4500psi fill is a real threat to your safety.

and if it has Oxy in it, you are seriously asking for trouble.
DO NOT USE OXYGEN IN A PCP !

beyond that,...
where did you get that hose ? fittings ? etc.
Do you know what they are actually rated for ? is it MARKED on the hose ?
and what about a fill gauge, regulator or flow restrictor, bleed-off valve ?

so many things bad here.

I don't know what your experience or knowledge with HPA is... but from what I am looking at in your pic, I suspect there are some SERIOUS dangers going on here.

HPA is noting to take lightly or be negligent, careless, or lackadaisical about.

I've not seen a welding oxy bottle rated at 4500 psi before so I strongly suggest you vent that bottle asap and have it tested before using it again and only for its intended use. Welding.

High pressure air is no joke, use only proper cylinders designed for high pressure air. You need a SCBA carbon tank for 4500 PSI. There are many to choose from, make sure they are not expired (good for 15 years from manufactured date) and have a current hydrotest. (required ever 5 years)

The fill system is not the place to make due with inappropriate hardware.

I suggest contacting Joe Broncto at www.airtanksforesale.com to get propperly educated.

I trust these guys and they told me more than once it was a 4500 psi tank. It is filled with air, not straight oxygen. I told them it needed to be air. They are firearms guys and have been in the business for 30+ years. They know How dangerous oxygen is and know it was absolutely not what unwanted. The tank has been bled, but I don't have a gauge, so I don't know where it's at. The hose is a 10k psi hose.

There are 4.5k nitrogen tanks. Hopefully that's what it is not a oxy tank.

It should have a big label on it. Can you post a picture of it? I have never seen a 4500 tank without a guage, but it's possible they are out there. I would not trust "firearms" people. Airgun people more, but you should take it to a Dive shop to have it inspected and determine what it really is.

What every one here has said is sound advice under no circumstances use an Oxygen tank for HP air and get the proper valves and gauges for your fill station saving a couple bucks at the cost of being maimed or worse just is not worth it . Better to hand pump than cut corners with a used tank with questionable pedigree

CptMoonlight · « **Reply #10 on:** August 17, 2015, 12:24:06 PM »

I completely agree that this is sound advice. I won't touch it until I confirm that it is safe. If it isn't safe, it will be returned. Thanks for everyone's input.

CptMoonlight · « **Reply #11 on:** August 17, 2015, 02:46:23 PM »

I checked, it is compressed air and the tank is rated at 4500 PSI in good working condition.

I followed your advice and looked at Joe's air tank website. It looks like the appropriate rig I'm looking for is $190. It's the section that talks about nitrogen welding tanks and looks like it's a 6k psi rig. Do you know of anywhere else I might be able to find one of these? I've heard Joe is a fast talker and I would rather not have to deal with that.

QVTom · « **Reply #12 on:** August 17, 2015, 04:34:28 PM »

Good deal. That is not an oxy tank so all is good.

Joe is knowledgeable and friendly, his products are first rate and service is good too. You can try Airhog products but I think Joe is a better deal and has more to offer. Don't believe everything you read....... just about half

Thank you sir! I appreciate all of your advice, and believe me, I felt the headshaking and incredulity transported from all of the computers screens across GTA. I will continue to be careful concerning my air guns and equipment.

So now that we got it straight that your equipment is safe, here is what you need to bleed your line, instead of having to loose your brass nut.

From you pick it looks like you have 1/4" nPT fitting? If so this bleed will fit right in line. This company has all sorts of stuff so you could add a "T" with a gauge if you wanted.

I'm going to get a "Y" setup from the guys who own the tank. I'm leasing it. I'll be able to bleed it through the second tube. But that certainly looks easier! Thank you!

It will also waste less air - the longer your fill hose, and bleed hose are the more air wasted each fill.

Glad that you are on the right track with pressure rated equipment.
it is highly recommended that you use a GOOD quality gauge on your fill set up. The mini gauge on your disco is not accurate. They are known to be off by quite a bit. I have a couple that are off by 300 to 400 psi.

Well, dang. That's good to know. I've read a ton about the disco and haven't read that.
