Help with oldish centerflag inline reg.

I have a centerflag hyper regulator on my ans autococker. When I air the gun up it reads about 700 psi. The marker cycles fine. When I shoot, the needle drops to ~550psi and then goes right back to 700. I've cleaned the entire reg with rubbing alcohol, no oil. I understand oil with cause it to creep.

Has anyone experienced this and what was the fix?

Oil will cause it to explode, meaning you would basically have a timebomb on your hands. If you introduce any oil in a high pressure air reg and fill the bottle to the point where it heats up (what happens on a fast fill), that little amount of heat, compressed air, and oil is enough to cause an explosion. You did the right thing by NOT using oil. Always use the recommended lube from the manufacturer.

After you cleaned the entire regulator with rubbing alcohol, did you lube the orings?

Just to clarify, this is an inline reg. Not on a tank.

From what I can gather, the only oring you want to lube is the piston oring. I used dow33 there.

Never heard of an inline reg exploding due to oil...I followed the instructions here

The reg looks like this one

How are your chrono speeds? Is it shooting down during high ROF?

Prior to taking it apart to clean it, I could not get it to shoot over 200fps, and it was very inconsistent. That is probably a spring problem though. I built this gun from accumulated parts.

Next time I am near a chrono I will put the reg on another gun and see what it does, and put a known good reg on the gun in question and see what i come up with.

For now, I just want to know the proper way to service this thing, and what I should be looking for to get it working right.

Thanks for the responses so far guys

it sounds like you're doing everything correctly. I would also agree low velocity was probably a spring issue.

I used to have an old CP reg on an autococker of mine, and the gauge readings would drop 80psi+ when shooting. To watch just the gauge, it seemed horrible - but when chrono-ing, it was very consistent. So, that is what I was fishing around with my previous question - your PSI drop may be a non-issue.

I say get it chrono'd first, because at this point, it may be working perfectly, we just don't know yet.

I see what you're saying. I'm not really concerned with recharge rate. What I'm confused about is why I can't seem to get it to adjust. When i was chronoing it, adjustments made no difference. That's when I decided to put the gauge on there. I can turn the adjuster from all the way in to all the way out, and it will stay at about 700psi regardless, which I suspect is tank pressure which would mean that either

A) it isn't regulating jack ****
B) I have the gauge in the wrong port.

There are three ports. One is labeled "HP IN" which is the input, one that says "200-700psi," and one labeled "LP GAGE." I put the gauge in the port labeled gauge, I think the other port is a burst disk or something.

Rob mentioned lubing o-rings, so I'm wondering if he knows something I don't (high probability). I'm out of ideas :/
