Maddog Paintball Compressed Air Tank 48/3000

What Is the Maddog 48/3000 Paintball Tank?

The Maddog 48/3000 compressed air paintball tank is a lightweight aluminum HPA tank built for paintball markers that use compressed air or nitrogen. It holds up to 48 cubic inches of air at a rated service pressure of 3000 PSI.

Aluminum paintball tanks are a popular option for players who want a durable, affordable compressed air tank without jumping into carbon fiber pricing.

How the Maddog 48/3000 Tank Works

The tank has two key airflow points:

• Inlet: Air enters through the fill nipple.
• Outlet: Air exits through the pin valve at the top of the regulator.

The pin valve opens when the tank is screwed into the air source adapter on the marker, or when the silver plunger is tightened on a remote coil.

Before You Fill the Tank

Before filling any compressed air paintball tank, inspect the tank, regulator, and fill nipple carefully.

• Remove the fill nipple cover if one is installed.
• Check the fill nipple and make sure it is clean and free of debris.
• Confirm the pressure rating of your tank and regulator.
• If you are unsure, only fill to 3000 PSI.
• Maddog tanks show the rated pressure on the regulator directly above the fill nipple.

How to Fill a Maddog 48/3000 Paintball Tank

1. Attach the tank to the fill station hose using the fill nipple.
2. Check both the fill station gauge and the tank gauge.
3. The fill station gauge shows the pressure available from the fill station.
4. The tank gauge shows the pressure currently inside the tank.
5. Press the fill station lever to equalize pressure between the fill station and the tank.
6. Once pressure is equalized, both gauges should read the same pressure.
7. Release the fill station lever.
8. Remove the hose from the tank fill nipple.
9. Reattach the fill nipple cover.

How to Use the Maddog 48/3000 Tank Safely

• Screw the top of the tank into the air source adapter at the bottom of your paintball marker.
• If using a remote coil, screw the tank into the female attachment point on the remote coil.
• The remote coil can act as an on/off connection for the air source adapter.
• Tightening the textured screw-down plunger activates the regulator pin valve and allows air to flow.
• Loosening the plunger should close the pin valve and stop air output.
• Be aware that residual compressed air may remain inside the remote coil after closing the pin valve.

Check the tank gauge before use. A reading of zero means the tank is empty. You can slowly release remaining air pressure by gently pressing the pin in the center of the regulator at the top of the tank.

Basic Paintball Tank Maintenance

Maintenance is simple, but a little attention goes a long way. Before and after use, check the fill nipple, threads, pin valve, and tank o-rings for dirt, debris, or visible wear.

• Wipe away debris from the fill nipple, threads, and pin valve.
• Replace worn o-rings when needed.
• Use a fill nipple cover to help protect the fill valve from dirt.
• Never lubricate the fill nipple or fill nipple o-ring.

If the fill nipple leaks or you suspect the fill nipple o-ring has failed, replace the fill nipple o-ring. Do not lubricate the internal o-ring. Petroleum-based lubricants can ignite under the extreme pressures regularly contained within paintball tanks.

48/3000 Tank Safety and Storage

Important: Contents are under pressure. Read the entire label before filling or using this cylinder.

• Only trained personnel may fill the cylinder or repair the valve.
• Never fill the cylinder if it has not been hydrostatically tested within the last 5 years.
• Cylinders must be hydro tested within 5 years of the date stamped on the cylinder.
• Never overfill this cylinder or fill beyond its rated service pressure.
• Only use this tank with equipment rated for the specified cylinder pressure.
• Never expose the cylinder to flames, ovens, dryers, or other heat sources.
• Never expose the cylinder to temperatures greater than 125°F.
• Never alter the cylinder or valve.
• Do not expose the cylinder or valve to corrosive materials, caustic strippers, or cleaners.
• Do not drop the cylinder.
• Keep out of reach of children.
• Avoid breathing cylinder contents.
• Store in a well-ventilated area.

Failure to read and understand warnings can result in expulsion of the product or cylinder valve, or rupture of the cylinder, which may cause property damage, serious injury, or death.

This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm.

Danger: The cylinder and valve can separate with enough force to maim or kill if the valve unscrews from the cylinder. Watch the valve when removing the tank from the marker. Stop immediately if the cylinder starts to unscrew from the valve. Screw the cylinder back on and contact the manufacturer for repair instructions.

For filling and repair information, see Compressed Gas Association publications P-1, C-6.1, G-6.8 and AV-1. Additional filling and repair information is available through this compressed gas information resource.

Troubleshooting: Why Is My Paintball Tank Leaking?

If your Maddog 48/3000 tank is leaking, use the location of the leak to narrow down the cause.

Leak From the Fill Nipple

• Clear the fill nipple of debris.
• Replace the o-ring with size 006. Most paintball fields can help with this service.
• If the tank is still under warranty, contact support with your order number and a description of the issue.

Leak From the Pin Valve

• Clear the pin valve of debris.
• Test the pin valve by depressing the pin. You should feel resistance, and the pin should rebound into a closed position once pressure is relieved.
• If the pin valve is jammed, gently agitating the pin may fix it.
• Check the o-ring around the threads for signs of wear or failure.
• Make sure the marker air source adapter is turned off when attaching the tank.
• Only activate the air source adapter after the tank is fully attached.
• Replace the size 015 o-ring that seals the tank threads to the air source adapter when needed.
• If the tank is still under warranty, contact support with your order number and issue description.

Leak From the Burst Disk

• If the burst disk ruptures while filling or while stored under pressure, the affected parts must be replaced.
• If the tank is still under warranty, contact support with your order number and a description of the issue.

Leak While Using a Remote Coil

If the leak is coming from the tank attachment point, inspect the plunger, tank threads, remote coil attachment point, and tank o-ring.

• Make sure the tank o-ring is in good condition.
• Make sure the threads are clear of debris.
• Turn the textured plunger clockwise to activate the pin valve.
• If the plunger spins without moving up or down, use an Allen wrench to tighten the fastening screw recessed within the textured tank attachment point.
• If you lose air pressure when the remote coil is attached, finger-tighten the plunger clockwise as far as it will go, then turn it counter-clockwise 1/2 rotation. This should allow the plunger to activate the pin valve without blocking airflow to the marker.

Leak From the Marker Nipple Attachment

• If you hear a leak at the quick disconnect, turn the textured knob controlling the tank attachment plunger counterclockwise.
• Remove the quick disconnect the same way you would remove the tank fill nipple.
• Be careful: compressed air may remain in the remote coil and marker.
• Release compressed air before reattaching the quick disconnect.
• Make sure no debris is interfering with the quick disconnect.
• Reattach the quick disconnect, then turn the textured plunger clockwise to activate the pin valve and allow air into the marker.
• If the leak is between the marker and quick disconnect attachment point, make sure the marker air source adapter is activated and fully screwed into the back of the marker.
• You may need to replace the size 015 o-ring on the adapter if it shows wear or leakage.
