Unfortunately, you can’t thread the Talon P valve onto the larger bottles because it has odd threading. I saw someone selling an adapter out there, but I don’t remember where.
Pcp tunes sell the adapter for the talon p 5/8 valve tread to m18x1.5 tread in the bigger bottles .. but since shipping is expensive be sure to ad a few more things on your order... or you could buy a paint ball bottle with 5/8 tread that would be a direct fit..
I bought a 350cc paintball bottle and used an adapter from PCP Tunes to fit that bottle to my TalonP. If I would have known that Talon Tunes had the adapter, I would have bought it from Tony.
