Broken O-rings and expansion chambers on Classic Mag

[poolboy51]

Hi I recently bought a Automag Classic with a Kapp drop forward and an ACI expansion chamber on ebay. When I got it to test it out, the o-ring on the drop forward broke. This is my first gun and Im not sure what type of rings to get and where to get them. Could anyone here please point me in the right direction? I was using C02. I also am having trouble removing the tube that goes from the expansion chamber to the bolt so I can take it apart. Can anyone tell me how to remove the tube? Do I pull it out of do you screw it out? Thanks.

Ok I will have a go at this. I am going to assume the O-ring on the "Drop Foward" you are talking about is your "Tank O-ring".I assume you screw your tank into your drop. These are usually found at any paintball shop, scuba shop and even K-mart may have them in the sporting goods dept. This O-ring is very common to break especially when using CO2. So if you pick these up get a bunch. They are not that expensive. If I am way off I appologize. The tube that you refer to going from your chamber to the valve, I again assume you are talking about Micro or Macro line. If this is the case you will need to press down on the metal Fittings where the black tubing goes in and at the same time pull out on the tubing. If the tubing is Stainless steel mesh then yes you will need to take a wrench and screw it off.
I hope this helps you out some.

THANK YOU! that was exactly the kind of answer I was looking for. I will go try both things you mentioned.

No problem

I hope these were what you needed to know. Let me know if it helped.

[poolboy51]

well, the fittings didnt come off no matter how much pressure I put on it. If, you have one, how do you get yours off?

[poolboy51]

heres a picture if my gun but you cant see the hose I need to take off. The o-ring INSIDE the thing Im pointing at(the black part)is the one I broke. I can get more photos if it will help.

You need to push back the fittings and then you can pull out your line. Sometimes players puts an oring in the bottomline so that they can get a better seal when screwing in their bottles. Some bottomlines has pins that are alittle long and opens the valve to early which makes air vent out of the bleed holes. I had to do that with my setup.

Your macro hose may just be hard to come off. Where the hose enters the fitting there is what looks like a metal ring that goes around the hose. You need to push this metal ring down onto the rest of the metal fitting. You may need to use pliers. While this ring is down pull out your macro hose. Now this may be tight. Don't be afraid to pull hard.

Thanks guys I got some o-rings today and tested the gun out; it worked beautifuly. I'll try to take the hose off again but last time I made quite a few strips and scuffs (not to mention cuts in my hands) and it still didnt come out. I'll try again though.

Hey again. I tried pulling as hard as I could but it would not come out. I have one more question about the o-rings. If I were to switch to an HPA or N2 tank, would the number of times my o-ring breaks be reduced?

[pbzmag]

As for changed to HPA, you will break the same amount of orings. What I used to do was oil up the oring and make sure that the threads on both the bottle and bottomline were clean. As for taking out the macroline, are you sure that your holding back the ring in the fitting while pulling out the macroline? You shouldn't have any problems. Also make sure that you degass the system before pulling out the macroline.

o-rings

Now if you switch to HPA you may not break too many orings. When I used to use CO2, my orings froze alot. This was a cause for premature breakage. HPA dosn't freeze. I agree with Pbzmag, lightly oil the oring with Pneumatic oil. Also sold in paintball stores as "paintball oil".

As for your Macroline.. If you have extra length to spare as a last resort you could use an exacto-Knife or a sharp pair osf scissors and cut the hose close to the fitting Bout 1/4" and then take a needle nose plier to the hose and yank it out. (still pressing down on the ring. If you do this and you screw up the fitting let me know. I have plenty of these 90 degree fittings and can put a couple in the mail for you. Again as Pbzmag stated, make sure your tank is off and there is no residual gas in your hose.

I totally forgot about freezing. I've used HPA for about 3 years now and haven't dealt with co2 since then. I was thinking about when you screw in your tank. When there's dirt on your threads it can mix with the oil and grind away at the orings. I just got a Flatline and don't have to worry about bottle orings anymore!

[gadget68]

ME TOO

I hear you Pbzmag, I also have a flatline and no longer worry about o-rings. But I keep a bunch in my tool box for my fellow paintballers. Especially the ones who still use CO2.
