How to Properly Remove Your Co2 Tank

This Side Up I recently had a question asking if it was OK to remove your Co2 tank if there was still Co2 in the tank. The answer is yes; but the question reminded me how often players at the field brake their tank's o-rings over and over again due to improperly unscrewing them from the gun. Ever have this problem? Here's why it happens...

The problem resides in the way you remove the tank from your marker. The first tip that prevents most o-ring breaks is to unscrew the Co2 tank face up. Why? The Co2 in you tank is in two forms: Gas and liquid. The liquid rests at the bottom of the tank since it's heavier, and the gas lays at the top. The reason why your o-rings break is because you have your tank face down, causing the extremely cold liquid Co2 to expel through the nossle while unscrewing the tank, freezing the o-ring and breaking it. Urethane o-rings aren't meant to be that cold. That's how they get destroyed.

The second common reason why your o-rings are breaking is simply due to a lack of lubrication. You by no means need a hefty amount of oil to lube the o-ring. I'm talking less than a drop of oil. I usually just put a little oil on my fingertip or cotton swab and layer the o-ring lightly.

O-rings don't cost much at all. You can find 500 urethane o-rings for a few bucks on the internet. So it's no big loss breaking a few o-rings once and awhile, but it's definitely an inconvenience to keep having to change your o-rings over and over... especially if you don't have any spares.

Peace.

    500 for a ‘Few Bucks’ ????? Are You OUT OF YOURE MIND???

    Never Happen!! I have run a Paintball Field for over 13 years, and the CHEAPEST I found them and only buying 1000+ is .07 each!

    Check eBay noob. There are so many online o-ring wholesalers who are more than happy to cut retail consumers deals.

  4. carlos rivera says:

    is it normal for the tank to make a big pop just before you unscrew it and is it normal ?

  5. kyle says:

    Carlos,

    Yes it is normal. When you unscrew your tank from the gun, the pin valve closes its airflow very quickly. This is the sound you’re hearing - it is normal.

  6. Zack says:

    Can you use a tank more than once on one filling after you remove it from the gun?

  7. bob says:

    how loud is the sound when u take the co2 tank off the paint ball gun

  8. Eugene says:

    u said it must be Cylinder side up and the gun barrel facing up instead of down, right. well how r u going to put it on the gun when it would be easier to put it on upside down. same way when taking it off….i also want to know if the CO2 can freeze the part that holds the CO2 on ur gun when taking it off. cause one time as i was taking the CO2 off it started to spray and freeze the CO2 holder..it freaked me out

  9. eugene says:

    how exactly r u going to put it on and off. it is kinda difficult to do this

    Never pay for urethane. Use Buna N. They last about the same and are dirt cheap. tankorings.com is where I get mine. You can also find them on eBay and other paintball websites. Beware, though, sometimes they will try to charge you urethane prices for buna. Expect to pay less than a nickel each.

  11. matt says:

    co2 sprays when removing from my gun, and tired of wasting co2, any way to stop this?is it normal?

  12. Keviin says:

    get a remote line.

  13. ferah says:

    I have a beretta co2 pistol and was trying to find out , what happens if you use your gun and then want to stop and there is quite a bit of gas left in the capsule. Is it ok to leave the capsule in there. I was worried about the pressure it still releases would this damage the guns performance.

    I dont know if it is ok, or how long you can leave it in there till its next use.

    Thanks guys
