O rings for co2 tanks
« on: July 18, 2015, 09:34:07 AM »
I got a 20 oz co2 tank that almost every time i take it off it breaks the o ring. What can i do to stop that from happening?

Never really dealt with co2 myself, but if I  remember right they tend to do that due to the cold temps they reach as the co2 expands.  The best fix, get a HPA tank. Best decision so long as the marker isn't one of the few that loves co2. Ninja makes some of the best regulators for them.

Orings are cheap. Really cheap. just throw a new one on there each time. have you looked in side the ASA of your gun to see if the threads are a bit messed up? that could be doing it.

If you are tearing orings every time then something is wrong with your ASA. Check the threads to see if there are no burrs or imperfections.

O-Rings for tanks are made from Bunanitrile, a material, that under cold temperatures becomes rsther constricted and weak. Combined with Carbon Dioxide(CO2) they become highly weak, and they swell when CO2 gets in them. This causes swelling, combined with sharp threads,  and small spaces, it causes breakage. Buy HPA :)

Don't worry about that. Like Alpha said, you can buy a lot of orings for the cost of an air tank -- especially if you buy a 50-100 pack from somewhere other than a paintball distributor. (I can't recall the exact size off the top of my head, anyone know?)

Definitely check the ASA for any burrs or sharp edges. You also can put a drop of oil on the tank o-ring to reduce wear.

Stock tank O-rings typically are urethane, but anyway you can get ancient O-rings at Scheels or Canfield's.  If you want newer, you can go to Swan engineering at 102nd J st. Be sure to take old o-ring with you, yes even if it is broken and they can hook you up. Madcow will have them as well.
When the going gets tough, stick to your Mud...
