Leaky A-5.....

[nu cidd]

Alright, my A-5 is leaking from the tombstone/power tube area. Its done this once before, and to fix it, I oiled up the o-ring on the thing that goes into the tombstone. But the threads in the tombstone are kind of messed up, there are very small sharp pieces of the treads comming off, and in general the inside of the tombstone isnt in the greatest shape. But the gun is not even a year old, and im not sure its the threads in the tombstone, because we put some teflon tape on the threads that go into the tombstone and it still leaked, and the o-ring was also replaced. Im thinking that the problem is in the power tube, because i can also hear it comming out of the barrel also. So its very confusing... Any help would be greatly appreciated.

U checked the powertube for any cracks? worst case scenario everything should be under warranty at Tippmann.

what tank are you using (co2 or hpa) and how much is left in the tank?

sometimes on low tanks, they leak from these areas... also, is the marker cocked before you air it up?

I've found that some tombstones fit loosely into the valve and can leak on occasion. If this is the problem, there is an easy fix:

Take the tombstone out. Borrow some clear (doesn't really have to be clear) nail polish from your girlfriend, family member, secret stash of drag queen outfits, or neighbor. Paint the back side of the tombstone with the nail polish. This is the side with the hole in it, through which air enters the valve. WAIT FOR IT TO DRY. Stick it back in and air it up. If it still leaks, you either didn't paint enough layers on or this isn't the problem.

It could also be:
cracked power tube, bad cup seal, bad valve o-ring, powertube o-ring, bad bottle o-ring, trying to air up the marker without cocking it first, cracked valve (rare, yes, but I've seen it), low tank pressure, misshapen tombstone, misshapen valve, or debris in any number of sealing locations.

If you want to replace that Tombstone, you can either try and see it Tippmann will replace it, or you can just go get one from Tippmannparts.com.

Well after I let it sit for awhile, I decided to cock it before I gassed it up, and there were no leaks. The power tube isnt cracked, and the o-rings are in great shape. When I gassed it up after it sat for awhile, I completely stripped the gun, wipped down everything, re-oiled, and put it back together. Im going to play some woodsball today, and the field owner has spare parts that may help, and alot of the guys there may help me out, but i'll try the nail polish when I get back, so thanks corrupted.

if it didnt leak, you dont need any parts...

[Corrupted355]

Yeah, if it doesn't leak when you cock it before you gas it, there's nothing wrong with your A-5. All that means is that the hammer was holding the valve open while you were attaching the bottle. The air pressure was not enough to overcome the drive spring pressure, and you had a leak. As Noely said, you need no parts or modification.

Well when I played, I cocked it before I aired it up, and it started to leak again, but it was a very quiet and slow leak. So I took it to the chrono, got it set to aroung 270, and the leak got a tiny bit quieter, so I let it sit while we went over the field rules, and while other people were setting up. I came back, and the leak was gone I was a little confused but I said what ever, re-chronoed, and started a game. It didnt leak once, even with all the heavy firing I was doing. So I used up the tank, and switched to my VS3 for the rest of the day, cause I didnt want to risk anything going horribly wrong. After the day was over, I still had some CO2 and paint, so I shot it at home, and still no leak:eek: . I havent taken it apart yet, cause I've been at school and doing homework. The thing is a tank though...

Where exactly is the leak coming from?

This is fairly common. Mine does it from time to time. It happens because the marker's been sitting for a little while, and the valve O-ring is dry. It's easy to prevent. Before you start playing, assemble the marker without the barrel and put a few drops of oil on the ASA. Dry fire a few times. By then it'll stop, and you can put your barrel on and go play.

I did that after playing, and no leak, so i guess before I play, I will oil up the gun the night before, and then put some drops in the asa the day of play. We were going to send it to Tippmann to see if they could fix it, because its still under warranty. Thanks for all of the help.
