Your cart is empty.If your screw-in co2 tank is leaking from the pin at the top of the valve, the most likely culprit is a worn/damaged pin valve seal. Captain O-Ring offers replacement pin valve seals to get your tank back in the game without the need for replacing the entire valve.
Note: These pin valve seals are designed for the pin within screw-in style paintball co2 tank valves. They are not the same as the puncture seal used for smaller 12 gram co2 cartridges in pellet/bb guns.
What to expect: This item includes five (5) CO2 Pin Valve Seals in a resealable zip-top poly bag with "Captain O-Ring" branded packaging. Manufactured and warrantied against defect for one year by Captain O-Ring LLC. "Captain O-Ring" is a registered trademark of Captain O-Ring LLC.

I had a paintball tank that wouldn't seal to matter how much I jiggled the pin. You need to be careful removing the valve from a paintball tank as any pressure still in the take will turn it into a projectile. I used a strap wrench to turn the tank and my vise to hold the valve. It took some force but wasn't too bad. Taking apart the valve and replacing the seal was a piece of cake. Putting back to together was also easy. So far (it has been over a month) the new seal is hold up fine. Much cheaper then buying a new valve. Good luck with your repait.

I bought these for a co2 powered bb gun. They are too small a diameter and too thick--I should have know better

Solved a leak due to damaged pin valve O ring in JT tank. Seems identical to the original. Beware that removing the original valve may be challenging.
