HPA 98 custom

Im thinking of using HPA on my 98custom and I was wondering if this is even possible to do without the internals exploding because of pressure or something like that. Anybody who has done this explain how they got this to work.

Just make sure you buy a high output pressure tank. Because a low pressure tank probably would not work unless you get a low pressure kit.

All right. Get a high output tank to save you having to get a low-pressure kit. Good Luck

as long as you have a high pressure tank you are good.  Make sure it is high pressure becuase if it is a low pressure tank your gun will be hogged of air.

Like it makes much of a difference...

Just make sure your tank is regulated hahaha.

Yes. Way better.

Re: Using the A-5 Or 98 with nitrogen.

Ok, so you want to convert your 98 or A-5 to nitro (HPA), but don’t know what else you need. Here’s your guide to converting your 98 or A-5 to a nitrogen-operated paintball gun.


Firstly, if you want to, you can run a stock Tippmann off nitrogen.  All you need is a tank, and you can screw it in and go shoot people.

If this is what you want to do, you will need a tank with certain specifications.


1. High output: The output on the tank has to be preset to high. This is the pressure that comes out of the tank into the ASA, and into the gun. It has to be set at about 800 or 850 PSI, so that the gun will still recock and function correctly. The other kind of tank is a preset low output tank. These are set to 400 or so PSI of output, and that is too low to run a stock 98 or A-5.  Some examples of tanks that would work on a stock tippmann are this one, or this one. The internal pressure (4500 or 3000) doesn’t matter, just the output pressure.

2. Screw-in tank. The nitro tank has to have standard CO2-like threads to screw into a regular ASA. Both of those tanks ^^ also are like that. Most tanks are. Only specialty tanks for expensive guns and such are not screw-in.


 

Ok, about the LP kit.  The Low Pressure kit for the 98 or A-5 is completely optional. It will increase efficiency, lower re-coil, and some say it will improve the accuracy of the gun, but it is not needed if you get a nitro tank.

 

If you do want the LP kit, you will need:
1. The LP kit itself
2.  A nitro tank
3.  A secondary regulator like an AKA Sidewinder.


The LP kit makes the gun use about 300 or 350 PSI of pressure to run (this is why you need the regulator). Because of this, your nitro tank can be low or high output, but high output will work a lot better.

 
High output is more highly recommended for several reasons.

1. You can use it on other guns. Especially if you have a back-up gun like a spyder or have a friend that wants to use your tank. That way you will still be able to get some of the benefits of nitro, and can use it universally.

2. The gun will run a lot better overall. The reason has to do with the regulator setup.  If you have 800 PSI going into a regulator, the reg. is brings it down to about 300. This way, you can be sure that the difference from the input into the reg and the output into the gun will always be at least 200 PSI (which is ideal for the regulator to work).


But if you have a low out-put tank, and are only putting 400 PSI into the regulator, the reg will only need to bring the pressure down by 100 or 50 PSI. This small difference in PSI will cause problems, and the reg will not work as well at high rates or fire.

If you use a low output tank, you still need to use a secondary regulator. The 400 PSI from the tank is still too high for the LP kit and then your setup will not work as well because of the regulator problem above.

Also, if you run multiple regulators, like a female ASA-style palmer stabilizer, and then a Sidewinder, your consistency will increase even more.

So overall,    high output nitro + regulator(s) + LP kit = best setup.

And if you don’t like either of those options, you can run your A-5 or 98 with nitrogen, a regulator, and no LP kit.

 

Hope you get it! Any more questions are welcome.

 

P.S.  -- I’m not really a nitro-specialist, I just put this post together from what I’ve learned. So instead of PMing me with questions, post it in this thread so everybody can see it. Good luck!

here is how to PROPERLY get the HPA to work with the gun,

step one: screw it in
