Standard bottle oring for the tops of CO2 and HPA bottles. These are high quality urethane orings. Urethane orings last much longer under pressure and are ideal for bottle orings.
These orings are used on the top of the CO2 tank that threads in to your gun.
One of the most common replacement items, this oring screws in over threads every time the tank is installed or removed. Easy to cut or nick. Extras are always handy to have. They are easy to replace and a must have to attach your air source.
It's a good idea to put a drop of oil on this oring everytime you screw your tank in. The oring will last a lot longer.
The easiest paintball problem to fix and the most common problem to have. The orings on the top of your tank wear out. They fall off. They get ripped, gouged, dried out, twisted dirty, etc. A bad oring causes leaks that affect your performance. Keep plenty on hand so your day isn't ruined by what should be an easy fix. BEST IDEA EVER?!: Use a twist tie to put several extra orings around your tank valve. You'll always have them when you need them.
