When I was trying to put in my new power tube, I stripped my valve, and the hose won't screw back into my valve. I don't know what to do, I don't really want to fork out the cash for a new one, becuase I live in canada, and after shpping, taxes and everything , it comes to about $80 for one, and I bought my gun for $120,,, so I can't really justify the price. if anyone has any suggestions on what I can do,,, and how,, would be awsome,,, like what is hte size of tap I would need to rethread the valve. or how to take apart and put back together the vavle... please, help,
help!

You can chase the threads with a tap and they may clean up enough to allow the hose to screw in properly. You will have to disassemble the valve. Rather than going into the description of the process again check "active topics" about leaking and leaking valves and you'll find a couple of explanations on how to take it apart.
The thread is 1/8" NPT (tapered pipe thread) do not take the threads deeper as the hose fitting may then go in too far and interfere with the function of the valve. Just clean the treads up with the tap entering the hole at the correct angle.
Be sure to use thread sealant when you re-assemble. Be conservative with the sealant, you don't want a gob to enter the valve and gum up the works. When you re-assemble, give the sealant time to dry before pressurizing the valve. You could use Teflon ribbon dope (tape) but that is not really intended to seal the threads like some of the liquid dope available. With the threads slightly messed up the liquid sealants will do a better job (Loc-Tite blue is one I like).

if using liquid sealants (pipe dope or loctite) do not pressurize right away let it stand at least 6 hrs. i believe teflon tape is better just my opinion though.

Teflon tape IS better.
I stripped out the SS line threads on the body before. I cross threaded it. It leaked with teflon tape, so I took out the line again, and tried to re-tap the threads. It "rejuvenated" the threads so they looked mormal, but there was still slits and extra room from where I cross threaded. Tried three layers of T.T., leaked, tried six, leaked, also tried Loctite, filled most of what I destroyed, but it still would hold the pressure completely.
So I bought a new valve body (may bolt threads were stripped too) and transplanted the valve internals.
Im sure Tippmann can send parts up to Canada. Call them and ask for a new valve or valve body. Warrenty will cover it if its active, if not a new valve (with internals) is $30, the body is $16+ shipping.

well, I gave up buying it new when they shipping company phoned me and asked for another 20 some
odd bucks. I got my gun used, and I found out that it is around 5 years
old. so,, do you think I should just buy an new valve? or how long do
they last, becuase then I would just buy a valve shell, or whatever it
is called. I am just thinking maybe the a new valve would work better in the gun.

It would be better to buy a new valve altogether. CVX valve can last a while, but your seals may soon go bad just from age. It would be a lot better to just replace it than ordering specific parts and taking it apart which is hard.
If you order it, buy from Tippmann.

I'm thinking about re-tapping mine and screwing cut off screws into it and then the tube just lifts out when I field strip the gun but the valve won't slide forward when I shoot.

i don't know if that's a good idea any play at all with that valve would cause inconcistant shooting, not to mention slop will only get worse over time the, valve hammering back and forth will elongate the holes very quickly. if you do try it keep a very close eye on the holes.

Are you forgetting about the line? Youll need to unscrew the line every time you want to "slide out the powertube". If you do find a way (you wont) to get around this, you will have a ton of problems because your valve body isnt secure. If its not secure, the rear bolt and blowback will pull the valve back, then it will smash forward when you fire again. Just like when your missing your valve bolts.

Come on! Suck it up! This is not rocket science, it's plumbing. If you cannot get the fitting on the end of the braided hose to start into the valve because it is damaged from the previous cross-threading, then pull the hose and swap ends. If you think yourself incapable of getting the damaged end to fit into the ASA (or worried about damage to the ASA) go buy another hose so it will have NEW fittings on both ends. You seem to have little mechanical inclination, this is the chance to learn...you will be better for it. If you intend to advance in paintball, such as attending tournaments, you need to learn your marker inside and out...be able to take it apart and fix it on the spot during that South American International Invitational with the top prize of $200,000, that you'll attend in a couple of years!

TIPPMANN IS AWSOME. They provided me with great customer service, and I should be able to get my problem fixed really soon. I just need to figure out, how do you install the vavle the best. I am trying to figure out, is there a trick on how you get your valve into the gun. thank you for your help, and you are all wonderful.
