CGA320-Paintball adapter issues.

I recently purchased a CGA320-paintball adapter, however having some issues of the extra hole on the side not being sealed. Threads have been Teflon taped and still having issues of CO2 coming out from the side.
Looks like hole was drilled a bit too high up...

Have you checked your paintball tank's o-ring for cracks/wear? Remove the tape. It's not going to do anything for you other than keep you from properly getting it screwed together.

O-ring looks to be in decent shape. Taping was just habit from a summers worth of being an apprentice plumber. I'll try screwing it on again and see if o-ring needs to be replaced.

If removing the tape and a new o-ring doesn't fix it, it could be defective. Pretty rare though.

Another thing I'm noticing is gas coming out of that top hole concurrently as the hole mentioned earlier (both circled)
Is that normal?
I had a 10lb cylinder before. But it is easier for me to deal with paintball cylinders. Hence the adapter.

What does the high pressure gauge on the regulator read?

I think it has a hole for pressure relief

I've completely emptied out 2 cylinders trying to figure this out.
Fresh o-rings, mineral oil lubrication. It's this adapter and the pressure relief hole that's doing a hole lot of negative.
I don't know where I should go from here.

Get some JB Weld and plug the whole if your not submerging the fitting. Make sure your using the right stuff for the type of metal the fitting is (probably aluminum) and make sure you remove the anodizing from it to prep the area. Oven cleaner works well in removing the anodizing from those types of parts.

Perhaps it's just a bad one.

Did you ever figure this out? I ordered one from toolmart750 on ebay that looks exactly the same. The hole on the side is so high that, if you look in it, you see above the washer.

That hole is definitely drilled too high. The hole is supposed to be in a position where it will be below the paintball tanks o-ring when it's screwed together. That hole is there to make it easier to unscrew a pressurized regulator from the tank. Once you unscrew it to the point where the hole moves above the o-ring, the hole will vent all the pressure still in the regulator. That hole should have been drilled in the last part of the inside threaded area.

Sorry for late reply. Yes i did get it from the toolmart seller. Yeah that hole is definitely drilled too high. Haven't had the opportunity to look at it since I posted that pic, i've been living overseas last few months, so care of has been under my dad... Would just soldering/welding that hole shut be good, but then again for $15 i can get another one like the one pictured:

On ebay has any had experience with this one? [ebay image attached since i think ebay links get taken down here]

the hole is sitting too low. I built a paintball reg using the same adapter. as you can see the hole on my adapter is toward the outter ring. make sure you use the cga320 nylon washer between the joint.
