Major leak thru tank connection

[Lobos]

Hey,

Just got a brand new Pro/Classic from airgun.com. It got here exactly on time and I'm happy with the customer support and all.

But, when I connect a tank to it, it just starts dumping all the CO2 thru the tank connection. I mean, it behaves as if I had no oring on the tank. I know its not the tank or the oring because I put it on my 'other' gun, a spyder, and it works just fine. Any thoughts on how to remedy this?

are you saying that it leaks around your tank/asa ??

[Lobos]

Basically, it leaks as if I had no oring on the tank itself.

Ok, you know where the tank is screwed in right? (I don't know what its called, might be ASA). It leaks thru there. Not thru the hose or anything, but the leak is in between the tank and the female connection. Again, as if the tank had no oring on it.

[Lobos]

I thought maybe the tank had to be all the way in to seal, but no luck, I screwed it in as far as it went and it still keeps leaking.

A couple of things to try.
Take some fine sandpaper and lightly sand the top of the threads in the asa. All you want to do is remove the sharp edge on the threads, a light three times around should do it. Clean any debris out of the asa after and lightly lube the threads.
Replace the tank oring and lube it also. (You could try lubing the oring first and trying that before any sanding).

[Lobos]

Hmm, I'll try that.

But it seems to me that the threads of the ASA were extended too far in so the tank valve actually opens up before a seal is made with the oring. I compared the spyder's ASA with the mags and there is quite a bit of difference there.

[kevdupuis]

AGD's asa are fine, they've just been known to have sharp threads, very sharp threads.

[Lobos]

Ok,

I tried sanding and lubing, no luck. Should I try teflon?

[kevdupuis]

The oring is ok, the tank works fine in another asa?
What you can do is put an asa oring in the bottom of the asa and use that to seal the tank when you screw it in, Ive done this a few times on problem asa's and it works.
Just remember you have it there whenever you unscrew the tank.

[Lobos]

Ah, that one helped.

Guess I'll have to use this quick fix until I get a dropforward or something.

Thanks for the help.

the problem occurs when the nub inside the ASA is a bit long for the tank you are using and activates the pin valve on your tank before everything is sealed up properly. You should be fine with another ASA, but the o-ring will work as a fix for now, just remember to to either have some extras on hand or carefully remove the tank so it doesn't fall out.

Another remedy is to grind down the nub inside a little, butjust be VERY careful as not to mess up the inside or go too far

Question

Great, got to play with it today. Played 'scenario' on some abandoned buildings and in the jungles sourrounding it (yes real jungle, not woodsball). So it had some harsh treatment, high temperatures, high humidity and even dirt and rain.

Must say, great gun. Other than that ASA problem that was easily fixed I had no problems at all. I didn't have to do anything other than clean and oil it at the end of the day. I put about 400 rounds thru it, with only 1 break since I got a bit eager on the trigger as I gave some suppressive fire as one of my guys moved up on an opponent, not bad for a gravity fed VL200

Just ONE question:
The manual says to put oil in the inlet closest to the valve? Where is this inlet? Is it in the ASA, where the CO2 goes into the gun?

Found the 2 -OIL- Holes in the valve body.

Now saving up my paychecks to get a 12v Revvy and some miscellaneous stuff I need.

I call the AGD Tech guy about this. Yes, the oil goes into the ASA. The manual said 3 drops after each usage, but the Tech guy said 1 -2 drops once a month would suffice. Since I don't like to take off my tank, the Tech guy said that I could remove the macro line at the X-valve and put the oil there. That seems to work fine.
