Fill Paintball Nitro Tanks

Fill Paintball Nitro Tanks

Paintballing is a fun and exciting game. It allows you to safely shoot your friends while still practicing survival tactics in a fast-paced environment. The only downside to the sport, besides the welts, would perhaps be the expense incurred with constantly buying new paintballs and reloading your paintball gun’s nitro tanks. Both, however, are necessary to enjoy the sport. Filling the nitrogen tanks on your gun can be an easy task, but one that should be handled with care and safety.


1. Stand the SCUBA tank upright, with its base on the floor. Make sure that the tank’s nozzle is completely shut off and turned tight.

2. Thread your nitrogen tank fill station’s male (threaded) end into the female hole of the SCUBA tank’s nozzle. A fill station is a device that should come with a gauge and outputs that allow you to connect the SCUBA tank with your gun’s smaller nitrogen tank. While screwing the device into place, make sure that you thread carefully and smoothly. If you have to force it, there is a chance that some threading has gone bad, or that there is something blocking the threads. Wipe down both pieces’ threads with a wet rag, removing any debris, and try again.

3. Make sure the bleed valve on the fill station is closed, then attach the paintball gun’s tank to the fill station. The gun’s tank should simply be a nipple-like extension that you can slide into the fill station‘s female quick-disconnect slot. Depending on the type of the station, you may have to pull back a metal covering on the female disconnect slot to allow the tank’s nipple to slide in. Do so if need be, and then slide the metal covering back into place.

4. Determine the pressure rating of the gun’s nitrogen tank. This will be written on the side of the tank, and is very important to not exceed. Problems of overfilling range from simple jams in the gun, to more serious popping and exploding of parts. Always be wary of the gun’s nitrogen tank’s pressure rating.

5. Slowly open the SCUBA tank’s pressure valve, keeping an eye on the gun tank’s pressure gauge. The gun tank’s pressure rating will determine how much nitrogen to put into the tank. If both the SCUBA tank and the gun tank rate at 3K, then slowly open the SCUBA tank’s valve and listen for the hissing to stop. If the tank on the gun is rated lower (as will be likely) than the SCUBA tank, then shut off the SCUBA tank‘s valve as soon as the gun-tank’s pressure has reached its recommended level.

6. Close the SCUBA tank’s pressure valve completely when the gun’s pressure has been reached. Make sure that the hissing has stopped before moving on. If you still hear hissing, feel free to use the wrench to tighten the valve as necessary (never over tighten, though).

7. Open the fill station‘s “bleed valve,” usually located on the underside of the device. This will get rid of excess pressure that has built up inside the device, and anywhere else. It is a safety measure that should always be followed.

8. Disconnect the gun from the fill station (possibly by sliding the metal covering mentioned in step 3 back, depending on the type of fill station). The nipple of the gun tank should slide out.

9. Cap the nipple with the attached plastic covering to keep it dirt and dust free, and set the tank and gun aside.

10. Disconnect the fill station from the SCUBA tank, and set both of them in a safe area. SCUBA tanks should be chained to the wall if possible, to keep them from falling over. Once everything is secure and in a safe area, you are ready to play.
