You have the newer style end cap much easier to swap out the o-ring

BNR (nitrile) O-rings will absorb CO2. They last for a while then swell and perhaps will blister like what you got. My QBs came with a chalky brittle white O-ring that leaked within weeks of service.
If you use a material safe for CO2, your seals will last a long time. I have been using EPDM O-rings in my QB rifles without any problems for 2 yrs. Urethane can also be used, the O-rings on the paintball tank is usually Urethane.

Ace?
Did I send you something not too long ago? Some sort of 2240 part? Could you do the same for me and send me three of those O-rings? Also with the PM where you ordered them in Canada?

Thanks!!!

Badlands Paintball out of Calgary have a web site. Contact them. Or make a trip to Wekend Warriors. They will get you set up with urethane orings. Co2 in liquid form. Is not only a cryogenic liquid it also is corrosive. Hence the absorbtion into buna and nitrile materials.

My dad is going to see what he has at work
He knows he has some but not sure about the urethane
We will also cheak a few local places
The seal shrunk back down enough that i could use it :)
Its doing 1 ish groupings at 50 yards with the QB :twisted: (not accurate enough :rolleyes: )

Your dad will probably have nitrile rings at work. They will work well if your not constantly wanting change back and forth from caplets to bulk. I had a pistol on bulk that retained liquid CO2 for over 10yrs. So nitrile will work but urethane is better especially for abraision purposes.(on off)
