Piston problem again

Alright, so I'm looking in my garage for some junk for my cannon and I see this box full of old plumbing supplies. I look in it and find this thick rubber toilet sealing thing covered with brown stuff lol, so I cleaned it up and put it on my piston and it works perfectly.
Here's the problem, I brought it outside and started filling it up . It took a few tries, but it finally filled up to 60 psi almost instantly. I removed the compressor hose from my gun, and when I open the valve, all of the air rushed through it instead of the barrel! The valve that I'm using is here:

It's 1/4 and I know you guys said at least 1/2 but I was at least expecting something to happen. Does anyone know whats going on? Thanks for your time.
Also: A little bit of air leaks through the bolts that I use to seal the end cap on, I used teflon tape but it still doesnt seal, Should I just seal them with epoxy after I fix the gun? I can probably find weak epoxy that I can break easily just incase I have to open it up again.
What else can I use to seal the bolts?
HELP!
EDIT: Ok now I'm really mad. 80% said the problem was the pilot valve, so Instead of the 1/4 ball, I added a sprinkler valve. I pressureizd it to 60 psi, and pull the blowgun and all the air comes out of the sprinkler valve, not even a little came out of the barrel. $40 later and no difference.
