A HPA Paintball tank provides compressed air to fire paintball rounds from a gas-powered paintball gun or rifle. You can fill an HPA tank at home, providing you’ve a source of gas to fill it with, for example, a scuba tank. You also will need a HPA valve adaptor, but no special mechanical or electronic skills. Filling a HPA paintball tank at home rather than at a HPA fill station at a hobby shop or gun store will save you money and time that could be better spent in playing paintball.
1. Stand the scuba tank next to a floor lamp. Turn on the floor lamp. Place the open mouth of the HPA valve adaptor against the nozzle at the top of the scuba tank.
2. Wrap duct tape around the HPA valve adaptor where it meets the sides of the nozzle.
3. Slowly turn the valve on the top of the scuba tank. Listen for the hissing sound of escaping gas. Wrap additional duct tape around the sides of the nozzle, if necessary, until no hissing can be heard. Turn the valve on the top of the scuba tank in the opposite direction to shut off the gas.
4. Place the nozzle of the HPA paintball tank onto the nipple of the HPA valve adaptor. Turn the valve on the top of the scuba tank to turn on the gas.
5. Push the nozzle of the HPA paintball tank against the nipple of the HPA valve adaptor. Hold the nozzle against the nipple until the sound of gas filling up the HPA paintball tank ceases. Turn off the valve of the scuba tank.
6. Slowly pull the nozzle of the HPA paintball tank off of the nipple of the HPA valve adaptor. The HPA paintball tank is now filled and can be reattached to the paintball gun or rifle that it is designed to power.
