Paintball Co2 Venting Problems


Hi everyone.

Today I purchased a Titan Controls Co2 Regulator.

For space issues I decided to purchase a 20oz Paintball Co2 tank.
I then of course purchased an adapter to connect the paintball tank to the regulator. The Co-2-Go to be specific.

The problem I'm having is that when I screw everything together, all of the co2 will start venting out of the hole of the adapter.

A few curious things I've been able to replicate.
When I screw it on initially, I will get pressure readings, but as soon as I open up the flow valve, it will instantly start venting through the adapter again. But I can only replicate that if I completely separate the tank from the adapter and try and screw it back together.

Thank you in advance for the help.

Are you putting the crush washer between the adapter and the regulator? Does your paintball tank have a clear oring on the end of it? Are there any weird burrs on the inside threads of the adapter that could be interfering with the paintball oring? Post pictures if you can, it will help.

There is definitely an O ring on the Paintball canister. And the Crush ring is between the regulator and the adapter.

Here are pictures as well.

Thank you again. I sincerely appreciate it.

Simple and common mistake. Take off that pipe tape on the adapter. The seal is made by the crush washer alone. Tighten that adapter on to your regulator pretty tight, not like lugnut on a car tight but maybe half of that. The crush washer needs to get deformed in order to seal.

Edit: half the torque of a lug nut might be a little much, I found a safety pdf that calls out 20 ft/lbs for a cga320, with a max torque of 30 ft/lbs.

Depending on the adapter, it can have a vent for when you unscrew the tank. (the theory is as you unseal the tank the pin seals the bulk of the co2 and the excess left in the system vents from the hole.) The o-ring is seal above that hole (in theory). I've had some cheap co2 adapters where the feature that depress the pin is too long and the vent location be incorrect.

So, ive taken the tape off. Used two wrenches for leverage to tighten the adapter to the regulator and still the same problem. Granted I'm not very strong. 120lbs of pure scrawny here. So I'll keep trying.

Check to see if the oring on the paintball tank is torn or cracked. Also, make sure you're getting it screwed on all the way.

I think I fixed it. Replaced the regulator washer with a Nylon one and a new O-ring on the Co2 tank seemed to do the trick.
