Replacing Your Kegerator Gas Tank

Step-by-step instructions for safely swapping out your gas tank for cold brew, kombucha, beer, and more.

What is a gas tank?

The gas tank powers your kegerator, pushing liquid from the keg to the tap using CO₂ or nitrogen. Without gas, your taps won’t pour—so when you’re out, it’s time for a quick swap.

How does replacing the gas tank create a better pantry experience?

Changing the tank yourself minimizes downtime and keeps your beverages flowing without waiting for a tech visit. It’s quick, easy, and satisfying—no service request required.

How do I replace my kegerator gas tank?

Here’s everything you need to do the swap:

You’ll need:

  • Wrench

Step-by-step:

office keg terminology

  1. Close the gas tank
    Turn the Gas Tank Valve clockwise until it’s fully closed.

  2. Turn off the shut-off valve(s)
    Flip the shut-off valve(s) so they’re perpendicular to the tubing. Most setups have one or two.

  3. Disconnect the regulator
    Use your wrench to loosen the hex nut by turning it counterclockwise. This will detach the regulator from the tank.

  4. Attach the new tank
    Remove the orange safety cap from your new gas tank. Tighten the regulator onto the new tank by turning the hex nut clockwise.

  5. Open the gas tank
    Turn the Gas Tank Valve counterclockwise. If you hear a hissing sound, tighten the connection at the hex nut—this indicates a leak.

  6. Adjust PSI and reopen the shut-off valve(s)
    Set the desired PSI using the Pressure Adjustment Knob. Then flip the shut-off valve(s) back so they’re parallel to the tubing.

  7. You're done!
    Great job. Enjoy your beverages—you're keeping the good times flowing.

Scenarios where gas tank replacement is most helpful

  • Your tap suddenly stops dispensing (usually mid-pour).

  • PSI gauge reads zero or below recommended levels.

  • You want to avoid waiting for a technician.

FAQs

What if I hear gas hissing after replacing the tank?
That usually means the regulator isn’t tight enough. Turn off the tank, re-tighten the hex nut with your wrench, then try again.

Do I need any tools besides a wrench?
Nope! Just a standard wrench is all you need for this job.

How do I know when it’s time to change the tank?
Check your pressure gauge—if it’s near zero or your beverages aren’t dispensing, it's time for a swap.
